Description

Technical Field

[0001] This invention belongs to the field of industrial automation technology, and in particular relates to a hardware module configuration method, apparatus, device and storage medium based on ECN bus. Background Technology

[0002] The ECN (Equipment Common Net) bus was developed based on the existing international standard EPA, specifically for the application characteristics of special equipment. The ECN bus is also developed based on the mature and reliable ZC series PLC bus, specifically for different application scenarios. The ECN bus is used not only for data communication between different PLC racks, but also for data communication between other types of equipment.

[0003] Currently, PLC systems based on the ECN bus include not only hardware modules and embedded software, but also PLC programming and configuration software, PLC monitoring software, PLC hardware configuration software, and the ECN bus itself. The PLC hardware configuration software primarily configures the current module topology, allocates addresses, and generates resource files. The PLC programming and configuration software mainly provides program editing, compilation, configuration, debugging, monitoring, and fault diagnosis services for PLC control devices. The PLC monitoring software mainly configures and monitors the monitoring screen. The ECN bus primarily enables communication between modules and racks. The variables used in the PLC programming and configuration software must match the channel locations in the hardware modules. Currently, the method used is for PLC programming and configuration engineers to determine the module's location information based on the manufacturer's instructions, and then define and use variables in the program accordingly. This process is labor-intensive and prone to errors. For third-party devices, the difference between the hardware module's design concept and the documentation makes determining the location locations more difficult.

[0004] To address these issues as much as possible, the existing solution involves embedded software matching the current hardware module configuration information with predefined module model information according to the module name, calculating the module's starting address based on certain rules, and fixing the point information in the software. However, this approach not only increases PLC startup time, wasting CPU, memory, and computer resources, but also leads to repeated software modifications due to hardware module changes, increasing software maintenance costs. Summary of the Invention

[0005] To address the aforementioned issues, the present invention aims to provide a hardware module configuration method and apparatus based on the ECN bus. This method and apparatus, by achieving hierarchical and low-coupling management of PLC programming software, embedded software, communication bus, and hardware modules, realizes the function of defining hardware modules once and making them universally applicable throughout the entire system, reducing the workload of engineering configuration and effectively improving work efficiency and accuracy.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a hardware module configuration method based on ECN bus, comprising the following steps: scanning all hardware modules in the current hardware configuration using hardware configuration software, parsing and configuring all hardware modules to obtain configuration information; mapping the configuration information to the CPU memory address of the PLC module to establish communication with all the hardware modules; downloading the programming software to execute the program based on the configuration information to realize the configuration of the PLC system based on trusted hardware module information.

[0007] In one embodiment of the present invention, the step of scanning all hardware modules in the current hardware configuration through hardware configuration software, parsing and configuring all hardware modules to obtain configuration information includes: calculating the configuration information and allocating resources based on the configuration information of the PLC module's CPU.

[0008] In one embodiment of the present invention, the step of obtaining the configuration information mapped to the CPU memory address of the PLC module to establish communication with all the hardware modules further includes: sending the allocated configuration information to the host computer; and updating the program based on the allocated configuration information.

[0009] In one embodiment of the present invention, the hardware module configuration method further includes, when updating or adding hardware in the current hardware configuration, the hardware configuration software rescans the current hardware configuration.

[0010] In one embodiment of the present invention, after parsing, all hardware modules are configured to obtain configuration information, wherein the configuration information includes: description information, resource information, and channel parameter information; the description information includes module name ID, board type, module alias, and module length description; the resource information includes channel name, address definition, channel type, channel variable type, and channel variable description; the channel parameter information includes hardware module type, channel name, channel type, default value, and parameter definition method.

[0011] In one embodiment of the present invention, the module length description further includes the number of DI channels, the number of AI channels, the number of RI channels, the number of PI channels, the number of DO channels, the number of AO channels, and the number of custom types.

[0012] In one embodiment of the present invention, the configuration information further includes basic hardware module information consisting of ModuleTypeID / SizeInfo, communication information starting address, configuration method, data link method, and parameter information.

[0013] Based on the same concept, the present invention also provides a hardware module identification device based on an ECN bus, and a method for implementing the hardware module identification based on the ECN bus, comprising: an information acquisition module, used to scan all hardware modules in the current hardware configuration through hardware configuration software, and configure all hardware modules after parsing to obtain configuration information; a synchronization module, used to obtain the configuration information and map it to the CPU memory address of the PLC module to establish communication with all the hardware modules; and a configuration module, used to download the execution program of the programming software based on the configuration information to realize the configuration of the PLC system based on the trusted hardware module information.

[0014] Based on the same concept, the present invention also provides an electronic device, comprising: a memory for storing a processing program; and a processor for implementing the ECN bus-based hardware module configuration method when executing the processing program.

[0015] Based on the same concept, the present invention also provides a readable storage medium storing a processing program, which, when executed by a processor, implements the hardware module configuration method based on the ECN bus.

[0016] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0017] 1. The ECN bus transmission messages of this invention contain device definition information on the communication link, which can be directly acquired and identified by embedded software. The embedded software uses this information to complete data acquisition, redirection, and data value conversion within the module channel. When hardware developers modify the device information, they only need to reassign the device model information; the ECN communication bus will still transmit data to the embedded software through the device model. The embedded software can then complete data acquisition, redirection, and data value conversion within the module without requiring program modifications.

[0018] 2. In this invention, when a new module is added to the hardware configuration or a third-party device is connected to the PLC system, it is only necessary to scan the hardware configuration via the ECN bus to obtain information on all modules in the current configuration. This information is then sent to the logic programming software via ECN messages. The logic programming software parses the message information according to the hardware module's definition model, obtaining the module's starting address, mapping method, channel parameter settings, etc., and generates the module's resource file, which is then sent to the embedded software. This completes the identification and information interaction between the embedded software and the hardware module.

[0019] 3. If hardware modules are added or module information is modified, this invention can complete the definition, control and communication of hardware modules normally without notifying embedded software developers and ECN communication bus developers to modify the program.

The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0030] The ECN bus transmission messages of this invention contain device definition information on the communication link, which can be directly acquired and identified by embedded software. The embedded software uses this information to complete data acquisition, redirection, and data value conversion within the module channel. When hardware developers modify the device information, they only need to reassign the device model information; the ECN communication bus will still transmit data to the embedded software through the device model. The embedded software can then complete data acquisition, redirection, and data value conversion within the module without requiring program modifications.

[0031] Preferably, the step of scanning all hardware modules in the current hardware configuration through hardware configuration software, parsing and configuring all hardware modules to obtain configuration information includes: calculating the configuration information and allocating resources based on the configuration information of the PLC module's CPU.

[0032] Preferably, after obtaining the configuration information mapped to the CPU memory address of the PLC module to establish communication with all the hardware modules, the process further includes: sending the allocated configuration information to the host computer; and updating the program based on the allocated configuration information.

[0033] Preferably, the hardware module configuration method further includes, when updating or adding hardware in the current hardware configuration, the hardware configuration software rescans the current hardware configuration.

[0034] When a new module is added to the hardware configuration or a third-party device is connected to the PLC system, the system only needs to scan the hardware configuration via the ECN bus to obtain information on all modules within the current configuration. This information is then sent to the logic programming software via ECN messages. The logic programming software parses the message information according to the hardware module's definition model, obtaining the module's starting address, mapping method, channel parameter settings, etc., and generates the module's resource file, which is then sent to the embedded software. This completes the identification and information exchange between the embedded software and the hardware module. If a hardware module is added or its information is modified, there is no need to notify the embedded software developer or the ECN communication bus developer to modify the program; the definition, control, and communication of the hardware module can be completed normally.

[0035] Preferably, after parsing, all hardware modules are configured to obtain configuration information, wherein the configuration information includes: description information, resource information, and channel parameter information; the description information includes module name ID, board type, module alias, and module length description; the resource information includes channel name, address definition, channel type, channel variable type, and channel variable description; the channel parameter information includes hardware module type, channel name, channel type, default value, and parameter definition method.
