Description

Technical Field

[0001] The present invention relates to the field of industrial automation, and in particular to a configuration method and device for field equipment, a networking method and a PLC controller. Background Art

[0002] Figure 1A The traditional industrial automation project deployment process is shown. To complete the configuration in advance using configuration software, it is necessary to clarify the type, role and device capabilities of each device in the industrial automation network. When configuring based on configuration software, it is necessary to import the device description information files of all devices supported by the project in advance so that the configuration software can obtain the device list in advance and have clear definitions and presets for the basic parameters and data range of each device. When performing configuration operations, it is necessary to select and confirm in advance according to the imported device list. During the configuration operation, all devices required for importing the configuration will be selected one by one or in batches, and the relevant settings will be made before compiling and downloading to the controller. After the controller is connected to the field equipment and a communication connection is established, the configured terminal equipment completes industrial production and business processing according to the predetermined logic program.

[0003] This traditional configuration process requires the import of description files of all devices required for project deployment in advance. When the project is complex and has a large number of devices, not only is the workload cumbersome, but the operation of each device is also prone to configuration errors, resulting in recompilation and implementation. For system integrators or engineering design deployers, not only is work efficiency not improved, but errors are also easily introduced. In addition, for industrial automation production lines with intelligent upgrades, when the engineering configuration needs to be adjusted to switch production lines or process flows, traditional configuration methods usually require cold start and reconfiguration compilation and downloading to complete the new process flow configuration, which cannot achieve flexible production process deployment.

[0004] When performing configuration or engineering deployment based on traditional fieldbus, due to low bandwidth and poor real-time performance, it is impossible to obtain a large amount of device description information during device operation, which may affect the normal operation of the production line. Summary of the invention

[0005] In view of this, an embodiment of the present invention provides a configuration method and device for field equipment, a networking method and a PLC controller. The technical solution of the embodiment of the present invention completes the field equipment configuration based on the device description template of the field equipment type, and downloads the configured project file to the PLC controller; after the configured field equipment is online, the device description information is obtained, the device is initialized, and then the device is started according to the startup instruction issued by the PLC controller. When the project is configured for the first time, it is only necessary to import the device description template of the device type required by the project, instead of importing the description information files of all devices. This not only greatly reduces the difficulty of configuration operation and maintenance work, but also provides the necessary conditions for flexible production of the project.

[0006] In a first aspect, an embodiment of the present invention provides a method for configuring a field device, comprising: configuring the field device according to a device description template corresponding to the type of field device to be configured; compiling the configuration result, and instantiating the used device description template to obtain a project file of the configuration; and downloading the project file to a PLC controller.

[0007] From the above, by importing only the device description template of the device type required by the project when configuring the project for the first time, instead of importing the description information files of all devices of the required device type, not only the difficulty of configuration operation and maintenance work is greatly reduced, but also the necessary conditions for flexible production of the project are provided.

[0008] In a possible implementation manner of the first aspect, the device description template of each type of field device includes the following information set of the field device of this type: device class information, parameter class information, real-time data class information, and alarm data class information.

[0018] In a possible implementation of the second aspect, it also includes: when a new field device is added after the networking is completed, when there is no instantiation template of the device in the running configuration, the instantiation template of the device is obtained from the backup instantiation template library; when there is an instantiation template of the device in the running configuration, the device starts running directly.

[0019] From the above, the dynamic devices can be synchronized to the network without configuration through the backup instantiation template.

[0021] From the above, by importing only the device description template of the device type required by the project when configuring the project for the first time, instead of importing the description information files of all devices of the required device type, not only the difficulty of configuration operation and maintenance work is greatly reduced, but also the necessary conditions for flexible production of the project are provided.

[0022] In a possible implementation manner of the third aspect, the device description template of each type of field device includes the following information set of the field device of this type: device class information, parameter class information, real-time data class information, and alarm data class information.

[0023] As described above, the device description template includes the device class information, parameter class information, real-time data class information and alarm data class information of the field device of this type, so as to achieve full coverage of the device information data of this type to support any device of this type.

[0024] In a fourth aspect, an embodiment of the present invention provides a PLC controller, comprising: a configuration and operation module, used to run the engineering file obtained according to any implementation method of the first aspect; an information acquisition module, used to receive the device description information reported by each field device after each field device is online; a device initialization module, used by the PLC controller to instantiate the device description information of the field device according to the device description information of the field device to complete the initialization of the device; and a device operation module, used by the PLC controller to start and run each initialized field device to complete networking.

[0025] From the above, by importing only the device description template of the device type required by the project when configuring the project for the first time, instead of importing the description information files of all devices, it not only greatly reduces the difficulty of configuration operation and maintenance work, but also provides the necessary conditions for flexible production of the project.

[0027] In a possible implementation manner of the fourth aspect, the device initialization module is further configured to obtain device description information of each field device from the device through a broadband industrial bus after the device is online.

[0028] From the above, by utilizing the high bandwidth, high real-time and multi-node characteristics of the broadband industrial bus, detailed device description information of each field device can be obtained from multiple field devices to realize the initialization of the field devices in real time, so as to quickly start the network.

[0029] In a possible implementation manner of the fourth aspect, the device description information of each field device is generated according to a device description template of the device type and is written into the device in the form of firmware.

[0030] As described above, the device description information generated based on the device description template can be used to instantiate the device information. By writing the device description information into the device in a firmware manner, there is no need to provide a separate device description information file.

[0057] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0058] In the following description, the terms "first\second\third, etc." or module A, module B, module C, etc. are only used to distinguish similar objects, or to distinguish different embodiments, and do not represent a specific ordering of the objects. It can be understood that the specific order or sequence can be interchanged where permitted, so that the embodiments of the present invention described here can be implemented in an order other than that illustrated or described here.

[0059] In the following description, the numbers representing the steps, such as S110, S120, etc., do not necessarily mean that the steps must be executed in this manner. If permitted, the order of the previous and next steps can be interchanged, or they can be executed simultaneously.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein are only for the purpose of describing the embodiments of the present invention and are not intended to limit the present invention.

[0061] The embodiment of the present invention provides a configuration method and device for field equipment, a networking method and a PLC controller. During configuration, the field equipment is configured according to the device description template corresponding to the field equipment type to be configured; the configuration result is compiled, and the used device description template is instantiated to obtain the project file of the configuration; the project file is downloaded to the PLC controller. During networking, the PLC controller runs the project file; after each field equipment is online, the PLC controller receives the device description information reported by each field equipment; the PLC controller instantiates the device information of the field equipment according to the device description information of the field equipment to complete the initialization of the equipment; the PLC controller starts running each initialized field equipment to complete the networking.

[0062] The technical solution of the embodiment of the present invention is used for the networking of field equipment of industrial automation production lines. When configuring the field equipment project, it is not necessary to import the device description information files of all field equipment. It is only necessary to import the device description template files of the corresponding device types according to the equipment types required by the project, thereby reducing the difficulty of configuration operations and maintenance work. When the field equipment is powered on, the device information is instantiated according to the obtained device description information of the field equipment, so that the field equipment can solidify its device properties without relying on the production line, and can dynamically adjust the device properties and capabilities according to the actual production needs, which also provides the necessary conditions for the flexible production of the project.

[0063] The following describes various embodiments of the present invention in conjunction with the accompanying drawings. Figure 1B The application scenarios of the embodiments of the present invention are introduced.

[0064] The embodiments of the present invention are applied to Figure 1B The control system shown includes: a host computer, a PLC controller, a step redundancy device and a broadband industrial bus.

[0065] Among them, there is configuration software on the host computer, which is used to configure the field equipment to be configured. The host computer and PLC controller are independent computer devices; the PLC controller is used for application-level networking of field equipment and logical control of field equipment. The industrial bus is used to realize the physical connection between field equipment and PLC controller. The PLC controller sets the master station module of the industrial bus, and the field equipment is connected to the industrial bus through the slave station of the industrial bus.

[0066] In some embodiments, the industrial bus is a broadband industrial bus (AUTBUS).

[0067] Combine the following Figure 2A An embodiment of a configuration method for a field device according to the present invention is introduced. Figure 2AThe flow of an embodiment of a configuration method for field equipment is shown, including steps S1110 to S1130. This embodiment is run on the configuration software of the host computer.

[0068] S1110: Configure the field device according to the device description template of the field device type to be configured.

[0069] The configuration result is used to configure the field devices therein in an industrial automation process.

[0070] Among them, there are many types of field devices on the industrial automation production line, each type includes multiple devices from different manufacturers and different versions of the same manufacturer. The device description information files describing their specific attributes (such as roles and capabilities) may have differences in names, data types, etc. Configuration based on device description information not only requires a large amount of data to be imported, but is also difficult to maintain.

[0071] In some embodiments, the device description template of each field device type includes the following information sets of the field device of this type: device class information, parameter class information, real-time data class information, and alarm data class information, wherein each data item in each type of information is configured with the standard name and data type of the data item. In order to facilitate all types of device description templates to accurately and uniformly describe information, a basic information template is first defined, which defines basic information such as data types of various basic data items, and the device description template uses these basic data items to define its own data items.

[0072] From the above, configuration is performed based on the device description template defined based on the device type. There is no need to enter the device description information of each field device, which makes configuration convenient. At the same time, the device description template is used to standardize the same type of equipment, avoiding duplication of labor and R&D investment in adapting the same type of equipment from different equipment manufacturers to different industrial automation production processes.

[0073] S1120: Compile the configuration result, and instantiate the used device description template to obtain a configured engineering file.

[0074] The device description template used for configuration is instantiated, and the obtained instantiation module reserves a position for the data item of each specific device of the corresponding type. The reserved position can be realized by a structure, a pointer or a table, and the table can be a two-dimensional table, a linked list, etc. The device description template includes a complete set of information items of each specific device of the corresponding type, and the instantiation module reserves a position for each specific device of the corresponding type, so that the PLC controller can run the project file and support various field devices of each type to access the network.

[0075] Table 1 shows the device description template instantiation of a pressure transmitter using a two-dimensional table as an example. In the instantiation template, the data items reserved for both the device of manufacturer A and the device of manufacturer B are reserved. The device description template of the pressure transmitter has 13 items. Because the description information of the device of manufacturer A and the device of manufacturer B is not imported at this time, the actual number of data items of the device description information is unknown. The instantiation template reserves 13 items for the device of manufacturer A and the device of manufacturer B respectively. In the future, no matter what data items the device of manufacturer A and the device of manufacturer B have, they can be imported in the device information instantiation.

[0076] Table 1

[0077]

[0078] S1130: Download the configured project file to the PLC controller.

[0079] Among them, the PLC controller can not only realize the logic of industrial control, but also run the configured engineering files to network the field equipment.

[0080] In some embodiments, the engineering file includes control logic of the PLC controller over the field device.

[0081] In summary, a configuration method embodiment of field equipment facilitates configuration when configuring a project for the first time because only the device description template of the device type required by the project needs to be imported instead of the description information files of all devices, which greatly reduces the difficulty of configuration operation and maintenance work.

[0082] According to the following Figure 2B An embodiment of a method for networking field devices according to the present invention is introduced.

[0083] Figure 2B The flow of an embodiment of a method for networking field devices is shown, including steps S1210 to S1240. This embodiment is run on a field PLC controller and is used to network field devices on an industrial automatic production line to form an application layer network on the industrial automatic production line.

[0084] S1210: The PLC controller runs the engineering file for field device configuration.

[0085] The engineering file is obtained through an implementation of a configuration method for field equipment and downloaded to a PLC controller.

[0086] S1220: After each field device comes online, the PLC controller receives the device description information reported by each field device.

[0087] In some embodiments, the PLC controller obtains the device description information of the device from the online field device through the broadband industrial bus (AUTBUS). The AUTBUS bus has a large bandwidth and can transmit device description information files with large amounts of data; the AUTBUS bus has more than 200 nodes and can connect many field devices.

[0088] The PLC controller is equipped with a master module of a broadband industrial bus, and a slave module of a field device is connected to the broadband industrial bus. The slave module can be on the field device or an independent device.

[0089] In some embodiments, the terminal manufacturer of the field device generates device description information for each field device according to the device description template of the device type, and writes it into the device in the form of firmware. When developing the device, the terminal manufacturer edits the device description template file of the corresponding device type or generates device description information firmware matching the actual terminal device attributes through software, and writes the firmware to provide it to the integrator or other terminal device party together with the device, without having to export the device description information file separately as a file to provide to the system integrator and the end user.

[0090] S1230: The PLC controller instantiates the device information of the field device according to the acquired device description information of the field device, and completes the initialization of the device.

[0091] Among them, the device information instantiation process is actually to associate and concretize the information of an actual device with the instantiation template based on the specified type, and associate the device description information of the actual device at the position reserved for the actual device in the instantiation template of the specified type, so as to achieve the correspondence between the device description information of the actual device and the data items in the device description template. Because the execution logic in the configured engineering file is based on the data items in the device description template, the description information of the actual device is corresponded to the data items in the device description template through the device information instantiation, so that the data of the actual device can be used to perform correct processing in the actual business data collection and control process.

[0092] Continuing with the two-dimensional table as an example, Table 2 shows the instantiation of the device information of the pressure transmitter. The device description information of manufacturer A has 6 items, and the device description information of manufacturer B has 8 items. During the device information instantiation process, in the instantiation template of the pressure transmitter, the corresponding data items in the device description information of manufacturer A are associated with the position reserved for the device of manufacturer A, and the corresponding data items in the device description information of manufacturer B are associated with the position reserved for the device of manufacturer B, so that the device description information of manufacturers A and manufacturer B corresponds to the data items in the device description template, so that the data of manufacturers A and manufacturer B can be used to perform correct processing in the actual business data collection and control process.

[0093] Table 2

[0094]

[0095] In some embodiments, when each field device is initialized, a redundancy check and a redundancy backup are performed on the instantiation template of the device based on the device description information reported by the device. In the initialization phase of the network composed of field devices, the device goes online in a static or dynamic manner, and a redundancy check is performed on the device description template based on the device description information reported by the device after it goes online, confirming that the device description information matches the instantiation template, and completing the redundancy backup of the instantiation template of the device. In other embodiments, an alarm may be issued when an inaccuracy occurs during the check, allowing the user to replace the device or import the device description information in other ways.

[0096] S1240: The PLC controller starts running each initialized field device to complete the networking.

[0097] Among them, the networking is based on the network initialization after the configuration engineering. After the field equipment is running, the PLC controller performs industrial control on the field equipment and completes related industrial operations.

[0098] In some embodiments, when each field device is running, the integrity and correctness of the instantiation template of the device is checked based on the operating data of the field device. This check will not affect the normal operation of the PLC controller or the network. In other embodiments, when an inaccuracy occurs during the check, an alarm can be issued to allow the user to replace the device or otherwise import the device description information in order to re-enter the network.

[0099] In some embodiments, when a new field device is added after the networking is completed, if there is no instantiation template for the device in the running configuration, the instantiation template for the device is obtained from the backup instantiation template library. Among them, when another device of the same type is added after some devices dynamically leave, its instantiation template can be obtained from the backup instantiation template library, so that the device is configured in the configuration. In other embodiments, when a new field device is added after the networking is completed, if there is an instantiation template for the device in the running configuration, the device starts running directly. For example, when some devices are added again after leaving dynamically, their instantiation templates and device information instantiation data are already in the running configuration, and can start running directly. From the above, the dynamic addition and departure of some field devices during the operation of the automated production line will not affect the production process, and there is no need to power off, restart or reconfigure, which greatly improves production efficiency.

[0100] In summary, an embodiment of a method for networking field equipment obtains a project file completed by a device description template based on a field device type, obtains device description information after the configured field device is online, completes the device initialization, and implements field device networking. By using a project file configured by a device description template based on a field device type for networking, dynamic changes of field devices are facilitated, providing necessary conditions for flexible production of engineering.

[0101] An embodiment of a dynamic networking method for field devices is described below in conjunction with the accompanying drawings.

[0102] An implementation method of a dynamic networking method for field equipment is a detailed implementation method that combines an implementation method of a configuration method for field equipment and an implementation method of a networking method for field equipment. It has all the advantages of an implementation method of a configuration method for field equipment and an implementation method of a networking method for field equipment, and performs redundancy checks and backups on the instantiation templates of the equipment, dynamically adds field equipment to obtain the instantiation templates that need to be updated from the backup, so that the equipment can instantiate the equipment information and start running without reconfiguring.

[0103] First, a control system for running an embodiment of a dynamic networking method for field devices is introduced.

[0104] Figure 3A The structure of the control system is shown, including: a host computer, a PLC controller, a synchronous redundant device and a broadband industrial bus.

[0105] The control system is Figure 1B The control system shown adds a synchronous redundancy device, which performs synchronous redundancy management on field equipment. The synchronous redundancy device can be a module independent of the PLC controller on the computing system where the PLC controller is located, or it can be a module on another computing system that shares the same site with the PLC controller and is deployed synchronously. Figure 3B The flowchart of an embodiment of a method for dynamic networking of field devices is shown, which includes steps S3010 to S3130.

[0106] Among them, steps S3010 to S3050 and step S3130 are run on the host computer where the configuration tool is installed to obtain the configured project files; steps S3060 to S3110 are run on the PLC controller to perform networking based on the project files; step S3120 is run on the synchronous redundant device to perform redundancy check and backup on the instantiated templates in the configuration.

[0107] S3010: Import the device description template, that is, use the configuration tool to import the device description template on the host computer.

[0108] Among them, the device description template of each field device type to be configured is imported. The device description template of each field device type includes the following information sets of the field device of this type: device class information, parameter class information, real-time data class information and alarm data class information. These information are defined based on the corresponding standard format with standard names, data types and information lengths. There can be several field devices of each field device type, but there is only one device description template imported for this type. Figure 4A An example of a device description template for a field device type is shown, in which the name, data type, and length of each data item in the device class information, parameter class information, real-time data class information, and alarm data class information are defined, and some data items also include range information.

[0109] Figure 4B The relevant work of the device description template based on the field device type before engineering configuration is shown, including: editing the device description template AX of each field device type according to the basic information template, and importing the basic information template and the device description template AX of each field device type together when importing.

[0110] Figure 4C The main purpose of the device description template in the present invention is shown.

[0111] For system integrators, during engineering configuration, do not import the device description information files of all field devices involved in the project. You only need to import the device description template files of the field device types related to the project. The device type template instantiation is completed during configuration compilation.

[0112] For the terminal party, when developing the equipment, the device description template file corresponding to the field device type is edited or the firmware of the device description information matching the actual terminal device attributes is generated through software, and the firmware is written and provided to the integrator or other terminal device parties together with the field device. There is no need to export the device description information file separately as a file to provide to the system integrator and the project user. For the project user, there is no need to maintain and manage the device description information file of each device on the production line, which reduces the construction cost and improves the efficiency of operation and maintenance.

[0113] S3020: Create a new project, that is, create a new configuration project on the host computer through the configuration software to obtain the configuration project file.

[0114] Among them, the project configures the field equipment, obtains the engineering files to network the field equipment for industrial control.

[0115] S3030: Device configuration, i.e. configuring the field devices to be configured through configuration software on the host computer.

[0116] The imported device description templates of various types of field devices are used for configuration, and there is no need to configure according to the device description information of the actual field devices.

[0117] S3040: Configuration compilation, that is, compiling the configuration code through the configuration software on the host computer to obtain the configuration project file.

[0118] In the compilation process, the device description template of each configured designated field device is instantiated to obtain the instantiation template of the field device, and the basis is provided for the instantiation of the device information of the corresponding type of device according to the instantiation template of the type of device.

[0119] S3050: Configuration download, that is, the host computer downloads the configuration project file to the PLC controller for configuring and connecting the field equipment to the network.

[0120] S3060: Configuration startup, that is, the PLC controller runs the configured project file and waits for the device to go online and access the network.

[0121] Wherein, step S3090 is also called at startup to perform redundancy check and redundant backup on the instantiated templates of each field device.

[0122] S3070: Device initialization, that is, the PLC controller obtains the device description information of the field device through the wide industrial bus, and initializes the online field device accordingly.

[0123] Among them, after the field device is online, the field device uploads its device description information to the PLC controller through the broadband industrial bus (the broadband industrial bus is AUTBUS). The device description information reflects the role and production capacity of the device in the industrial automation production process. This information is used to instantiate the device information of the instantiation template of the field device, that is, to confirm the actual capacity of the device in the current project. After the PLC controller confirms that the device description information instantiation is completed, it notifies the device to start running.

[0124] Figure 5A The structure of the broadband industrial bus network is shown. The PLC controller is the master station of the broadband industrial bus, the field equipment is the slave station of the broadband industrial bus, and the master station of the broadband industrial bus allocates bandwidth to each slave station.

[0125] When initializing the field device, step S3090 is also called to perform redundancy check and redundancy backup on the instantiation template of each field device based on the device description information.

[0126] S3080: Equipment operation, that is, the PLC controller starts the field equipment to start running according to the real-time cycle.

[0127] When the field device is running, step S3090 is also called to confirm the integrity and correctness of the instantiation template of the field device based on the operation data of the field device.

[0128] Figure 5B The process of automated production operation based on broadband industrial bus is shown. In the equipment initialization stage, the master station of broadband industrial bus broadcasts information such as bus cycle and bus working mode, and the slave station of broadband industrial bus corresponding to the online field equipment establishes communication with the master station of broadband industrial bus according to the information; the online field equipment reports the device description information of each field equipment through broadband industrial bus, which is used for PLC controller to instantiate the device information. The PLC controller instantiates the device information of the field equipment, and then broadcasts and synchronizes and starts the online field equipment through broadband industrial bus; in the startup stage, the PLC controller completes the device information confirmation, and notifies the online field equipment to start running through the broadband industrial bus; in the operation stage, the field equipment reports real-time operation data to the PLC controller through broadband industrial bus. In the process of realizing flexible production or dynamic networking, the industrial automation production line needs sufficient bandwidth to complete the timely and accurate dynamic reporting of field equipment information, and it cannot affect the normal industrial automation production. The low bandwidth and poor real-time performance of traditional field bus make it difficult to meet the needs of flexible production, and the complex networking caused by the need for switches of real-time Ethernet cannot meet the flexible needs of flexible production for network equipment and networking. Broadband industrial buses provide a communication method with large enough bandwidth and good enough real-time performance, and network field devices can be plug-and-play, which can meet this demand.

[0129] Among them, up to this step, the on-site equipment has completed networking.

[0130] S3090: Confirm that a field device has left or joined, that is, the redundant synchronization device confirms that a field device has dynamically left or joined.

[0131] Among them, there is no need to rebuild the configuration after some non-critical field devices dynamically leave or join, and the PLC controller can complete industrial control in terms of control logic.

[0132] Some of these devices have their data deleted from the currently used configuration when they are dynamically left.

[0133] S3100: Configuration reconstruction check, that is, the redundant synchronization device confirms and checks whether reconfiguration is required.

[0134] Among them, critical field devices are not allowed to leave, and their departure will cause the control logic of the PLC controller to fail to work, requiring reconfiguration; the departure of non-critical field devices does not affect the control logic of the PLC controller (the logic has multiple branches to continue working by running different branches when non-critical devices leave), so no reconfiguration is required.

[0135] S3120: Determine whether recompilation is required, that is, the redundant synchronization device determines whether reconfiguration is required. If recompilation is required, step S3130 is executed, and if not, step S3120 is executed, and the redundant synchronization process is performed online.

[0136] S3120: Redundant synchronization processing, that is, the redundant synchronization device performs redundant synchronization processing.

[0137] Among them, this step is called when the configuration is started to complete the redundancy check and backup of the instantiation template of the field equipment; it is called when the device information is instantiated, and the redundancy check and backup of the instantiation template are performed based on the device description information; it is called when the field device is running, and the integrity and correctness of the instantiation template are confirmed based on the operating data of the field device; when the field device is dynamically connected to the network and there is no reconstruction of the configuration compilation, the instantiation template is synchronized, and the device initialization is notified to allow the dynamically added device to connect to the network.

[0138] For a detailed description of this step, please refer to the redundant synchronization method in an embodiment of a dynamic networking method for field devices.

[0139] S3130: Open the project, that is, open the original configuration project file through the configuration software on the host computer and reconfigure it.

[0140] Combine the following Figure 5C A redundant synchronization method of an embodiment of a dynamic networking method for field devices is introduced. The redundant synchronization method is a detailed implementation of step S3120 of an embodiment of a dynamic networking method for field devices.

[0141] Figure 5C The flowchart of a redundant synchronization method of an embodiment of a dynamic networking method of field devices is shown, including steps S510 to S560.

[0142] S510: Template instantiation redundant processing.

[0143] When the PLC controller runs the downloaded configuration project file, the template instantiation redundancy processing of this step is performed, and step S520 is called to perform redundancy check on the instantiated template data and step S530 is called to perform redundant backup on the instantiated template data.

[0144] S520: Instantiated template redundancy check.

[0145] When the PLC controller runs the downloaded configuration project file, this step is called by the template instantiation redundancy processing of step S510 to perform a redundancy check on the instantiated template, mainly to check the definition attributes of the data items themselves.

[0146] Among them, in the network initialization stage (also the device initialization stage), the field equipment goes online in a static or dynamic manner, and the PLC controller completes the device information instantiation based on the device description information reported by the field equipment after going online, and performs a redundancy check on the instantiation template based on the device description information to confirm the matching of the instantiation template.

[0147] S530: Template instantiation redundant backup.

[0148] When the PLC controller runs the downloaded configuration project file, this step is called by the template instantiation redundancy processing of step S510 to perform redundant backup of the instantiated template.

[0149] Among them, in the network initialization stage (also the device initialization stage), the field equipment goes online in a static or dynamic manner, and after the PLC controller confirms that the instantiated template matches the reported device description information, it performs redundant backup of the instantiated template.

[0150] When the network field equipment changes dynamically, the instantiation template and other processing can be restored based on the backup information.

[0151] S540: Runtime synchronization processing.

[0152] Among them, when the field equipment is running, the template instantiation redundancy check and backup processing based on the field equipment type will not affect the normal operation of PLC control or broadband industrial bus network. After the device information is instantiated, it will be processed in real-time cycle operation. It is necessary to confirm the integrity and correctness of the instantiated template based on the operating data of the field equipment. The integrity and correctness of the instantiated template are confirmed by calling step S520.

[0153] Among them, when the network field device is dynamically added and there is no need to update the instantiation template, this step notifies the PLC controller to synchronously delete the device information instantiation data, and also calls step S3080 of an embodiment of a dynamic networking method for field devices to start the operation of the field device.

[0154] S550: Determine whether the instantiation template needs to be updated.

[0155] Among them, the network field equipment changes dynamically, and the instantiated template in the networking is checked. If there is no update of the instantiated template, step S540 is executed, and the PLC controller synchronously deletes the device information instantiation data and starts the operation of the field equipment; if there is no update of the instantiated template, step S560 is executed, then the backup instantiated template is obtained, and the device information instantiation of the device is completed, and then the device is started.

[0156] S560: Obtain the backup instantiation template, and call step S3070 of an implementation method of a dynamic networking method for field devices, obtain device description information from the field device to instantiate the device information, and then start running the device through step S3080 of an implementation method of a dynamic networking method for field devices.

[0157] In summary, an embodiment of a dynamic networking method for field equipment is based on device description template configuration. When the dynamic field equipment is running, the instantiation template of the device is backed up. The field equipment is dynamically added to obtain the instantiation template that needs to be updated from the backup, so that the device information can be instantiated and started without reconfiguration. The dynamic addition and departure of some field equipment during the operation of the automated production line will not affect the production process, and there is no need to power off, restart or reconfigure, which greatly improves production efficiency.
