[0002] With the rapid development of industrial automation technology, remote IO plays an increasingly important role in industrial control systems and is widely used in data acquisition, equipment monitoring, and automation control. Remote IO connects sensors, actuators and other devices to the control system, realizing real-time collection and transmission of industrial field data, greatly improving production efficiency and system reliability.

[0003] However, in the existing technology, remote IO is mainly divided into two forms: blade type and integrated type. Blade type remote IO meets customer needs by combining different blade modules, while integrated remote IO adapts to different sensor types by producing different models of products. Although these two forms meet the diverse needs to a certain extent, the following problems still exist in the research and development and production process: Hardware design redundancy: For different functional combinations, a large number of PCBs with duplicated functions need to be designed, resulting in a waste of circuit design resources. In addition, the arrangement and combination of different functional units produces a large number of circuit board models, which increases the design complexity.

[0004] Production and inventory pressure: Various circuit board models need to be produced and maintained separately, which brings many inconveniences to inventory management, material preparation and production processes, and increases production costs and management difficulties.

[0005] Complex software adaptation: Each circuit board requires independent firmware for adaptation, resulting in a large number of firmware, high maintenance costs, and unnecessary trouble for R&D and production.

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] At present, the functional modules of remote IO are widely used in the field of industrial automation, but the existing technology has the following problems: the hardware design is complex and the modularization is low, resulting in a long R&D cycle and high production costs; the software firmware needs to be developed separately for different functional modules, resulting in high maintenance costs. The module combination flexibility is poor and it is difficult to meet the diverse market needs; the resource utilization rate is low and the module function cannot be dynamically adjusted according to actual needs.

[0036] Based on the problems existing in the existing technology, Figure 1 is a flow chart of a component-based implementation method of a remote IO functional module provided by an embodiment of the present disclosure, such as Figure 1 As shown, the specific process of the component implementation method of the remote IO functional module includes: S110 , splitting the original remote IO functional module into multiple minimum functional units according to preset rules.

[0037] In a specific implementation, the preset rule is, for example, splitting by sensor type, functional independence or performance requirements; the sensor type is, for example, digital input (DI), digital output (DO), analog input (AI), etc.

[0038] For different types of sensors, the original remote IO functional modules are split into independent minimum functional units; For the functional groups that can work independently in the same type of sensor, the minimum number of groups is directly taken to split into multiple minimum functional units. For example, every 8 of the 16DI can work independently, so the minimum number of groups is directly taken to split into 2 8DI units.

[0039] S120, designing an independent hardware circuit (sub-PCB) for each of the minimum functional units, wherein the minimum functional unit includes a shift register for generating a hardware ID for identifying a function of the minimum functional unit.

[0040] In a specific implementation manner, each minimum functional unit has a built-in 74HC165D serial-input and parallel-output 8-bit shift register, and the input is a hardware ID, which represents the ID of the minimum functional unit.

[0041] S130, combining the plurality of minimum functional units into a new remote IO functional module according to a target form, and generating a unique identifier including the hardware IDs of all the minimum functional units in the new remote IO functional module by cascading the shift registers.

[0042] Optionally, the target form includes a blade form or an integrated form.

[0043] Optionally, each new remote IO function module can accommodate 2 to 6 minimum function units, with a maximum of 6 minimum function units. For example, after 4 minimum function units are combined, the shift registers are connected together, and the 32-bit unique identifier UniqueID of the combination of the 4 minimum function units is read out through software shifting.

[0044] The ID length of each minimum functional unit is 8 bits. Excluding the default state of all 0s, there can be 255 types of minimum functional units.

[0045] The structural diagram of the connection of the four minimum functional units is as follows Figure 2 shown.

[0046] In a specific implementation, the functional module of the remote IO of the target form is combined into multiple minimum functional units according to preset rules, and the structural layout follows the hierarchical rules of input priority and digital quantity priority, specifically including: In the physical arrangement, the minimum functional unit of the input function is placed first, and the minimum functional unit of the output function is placed second; the physical arrangement, for example, the input functional unit is placed on the left, and the output functional unit is placed on the right; the minimum functional unit of the digital quantity function is placed next, and the minimum functional unit of the analog quantity function is placed, and finally the minimum functional units of other functions are placed; The power supply and communication interface of each minimum functional unit are uniformly connected through the combined motherboard, and the minimum functional units are fixed by a card slot type plug-in structure; the "card slot type plug-in structure" is specifically described, such as a guide rail type, a snap-on type, and the like.

[0047] Optionally, the shift registers are cascaded in the following manner: Connecting the shift register serial output terminal (Q7) of the first minimum functional unit to the shift register serial input terminal (DS) of the next minimum functional unit to form a chain cascade structure; The shift registers of all the minimum functional units share the same set of control signals, wherein the control signals include a clock signal CLK, an enable signal CE and a parallel load signal PL; The shift register output terminal (Q7) of the minimum functional unit at the final stage is used as a reading point of the unique identifier.

[0048] S140: The software system reads the unique identifier UniqueID and analyzes the function type and quantity of each of the minimum functional units.

[0049] In a specific implementation, it specifically includes: 1. Hardware triggers reading of UniqueID: The system triggers the shift register through control signals (CE, PL, CP) to read the cascaded 32-bit UniqueID. The specific process is as follows: In a specific implementation, the step of cascading shift registers includes: Pull down the shift register enable signal (CE) of all minimum functional units and activate the clock signal (CLK); Pull down the shift register load signal (PL) of all minimum functional units, then pull up the shift register load signal (PL) of all minimum functional units, and write the hardware ID of each minimum functional unit into the corresponding shift register through the parallel load signal (PL); Input continuous clock pulses (input 32 CP rising edges) to the CP pin of the shift register, read the combined 32-bit UniqueID, read the output of the last group of Q7 pins (i.e., ID_DO) from the output end (Q7) of the final shift register, and obtain the combined 32-bit unique identifier UniqueID; UniqueID example: If Slot1=8DI(ID=0x0), Slot2=8DO(ID=0x02), then UniqueID=0x00000102.

[0050] If Slot3=8AI(ID=0x03), Slot4=Counter(ID=0x0), then UniqueID=0x03040102.

[0051] 2. Parsing UniqueID Byte splitting: Split the 32-bit UniqueID into four 8-bit sub-IDs (Byte1-Byte4) by byte. A non-zero sub-ID represents the functional type of the valid minimum functional unit. For example: UniqueID=0x03040102 → Byte1=0x03, Byte2=0x04, Byte3=0x01, Byte4=0x02.

[0052] Function type identification: Look up the predefined hardware ID mapping table based on the sub-ID value to identify the type of the smallest functional unit. For example: 0x01 → 8DI 0x02 → 8DO 0x03 → 8AI 0x04 → Counter If the sub-ID = 0x00, it means that the slot is vacant.

[0053] Quantity Statistics: Count the number of non-zero sub-IDs to determine the total number of enabled minimum functional units. For example: UniqueID = 0x03040102 → 4 minimum functional units (8AI, counter, 8DI, 8DO).

[0054] UniqueID=0x00000101 → 2 minimum functional units (8DI, 8DO).

[0055] S150 . Adapt the modular configuration structure of the industrial communication protocol according to the analysis result, and map the minimum functional unit into a protocol submodule.

[0056] For the remote IO communication function, the software combines the combined module or integrated product with the remote IO communication protocol stack function and presents it to the user in a componentized form. The user can enable or disable each component individually.

[0057] In a specific implementation: 1. Profinet protocol adaptation: The concepts of Slot and Subslot exist in the Profinet protocol, and the corresponding Profinet modules can be represented by Module and SubModule.

[0058] In the componentization solution of the present application, the function module represented by the read UniqueID may correspond to the Module concept of Profinet, and the minimum functional unit may correspond to the SubModule concept. The software may be configured according to the configuration rules of Profinet.

[0059] Map the function module corresponding to the UniqueID to the Profinet module. For example, UniqueID = 0x00000101 (two 8DO minimum function units) is mapped to 1 module (Slot 1).

[0060] Map each minimum functional unit to a SubModule under the Module. For example: SubModule 1: 8DO minimum functional unit (Slot 1), data address 0x1000-0x1001.

[0061] SubModule 2: 8DO minimum functional unit (Slot2), data address 0x2000-0x2001.

[0062] In the Profinet protocol, each SubModule has a corresponding parameter configuration (called Record). Through Record, each minimum functional unit can be easily parameterized, including enabling or disabling the minimum functional unit module.

[0063] Through Record configuration parameters, including: Enable status: The enable / disable status of the SubModule is configured through Record 0x8000:01.

[0064] Function parameters: such as sampling rate (Record 0x8000:02), de-jitter time (Record 0x8000:03).

[0065] Configuration process: The user modifies the Record value through the TIA Portal, and the system synchronizes the value to the remote IO module and updates the hardware configuration.

[0066] 2. EtherCAT protocol adaptation: The concepts of Slot and Module exist in the EtherCAT protocol. In the componentized solution of the present application, the function module represented by the read UniqueID can correspond to the Module concept of EtherCAT, and a corresponding data entity is created and configured according to the configuration rules of EtherCAT.

[0067] In the EtherCAT protocol, each module also has its own parameter configuration, which is stored in the CoE (CANopen over EtherCAT) dictionary object. When the EtherCAT master is connected to the slave, it can parameterize the module by reading and writing the CoE dictionary object of the module, including enabling or disabling the corresponding minimum functional unit.

[0068] Map the function module corresponding to the UniqueID to the EtherCAT module. For example, UniqueID = 0x03040102 (8DI + 8AI + 8AO + counter) is mapped to 4 independent modules.

[0069] Dynamically adjust the PDO entries based on the smallest functional unit enabled. For example: Enable the 8DI minimum functional unit: add RxPDO 0x1600 to map 8-channel input status.

[0070] Enable 8AO minimum functional unit: add TxPDO 0x1A00 and map 8-way output control.

[0071] The minimum functional unit parameters, including enable / disable status, are configured through the CoE dictionary object. The user modifies the CoE dictionary object through the EtherCAT master tool, and the system updates the hardware configuration.

[0072] 3Optional, user scenario examples are as follows: Profinet scenario: Configuration: Enable the 8DI minimum functional unit and set the de-bounce time to 10ms.

[0073] Process: Modify the value of Record 0x8000:03 to 10. The system updates the GPIO configuration and filters the jitter signal.

[0074] EtherCAT Scenario: Configuration: Enable the 8AO minimum functional unit and set the output voltage range to 0-10V.

[0075] Process: Modify the value of CoE 0x8000:02 to 0-10V, and the system updates the DAC chip configuration.

[0076] By mapping the smallest functional unit into a protocol submodule and combining Profinet's Record with EtherCAT's CoE configuration mechanism, efficient adaptation of remote IO modules and industrial communication protocols is achieved, significantly improving the flexibility, real-time performance and maintainability of the system.

[0077] For the Profinet protocol, map the function module corresponding to the UniqueID to the Profinet Module. For example, UniqueID = 0x00000101 (two 8DO minimum function units) is mapped to one Module (Slot 1). Map each minimum function unit to a SubModule under the Module. For example: SubModule 1: 8DO minimum function unit (Slot 1), data address 0x1000-0x1001. SubModule 2: 8DO minimum function unit (Slot 2), data address 0x2000-0x2001. And configure the parameters through Record, parameter type: Enable status: The enable / disable status of the SubModule is configured through Record 0x8000:01.

[0078] Function parameters: such as sampling rate (Record 0x8000:02), de-jitter time (Record 0x8000:03).

[0079] Configuration process: The user modifies the Record value through the TIA Portal, and the system synchronizes it to the function module of the remote IO and updates the hardware configuration.

[0080] In a specific embodiment, it includes: For the EtherCAT protocol, the function module corresponding to the UniqueID is mapped to the EtherCAT module. For example, UniqueID = 0x03040102 (8DI + 8AI + 8AO + counter) is mapped to 4 independent modules. Dynamically adjust the PDO entry according to the enabled minimum functional unit. For example: Enable the 8DI minimum functional unit: add RxPDO 0x1600 to map the 8-way input status. Enable the 8AO minimum functional unit: add TxPDO 0x1A00 to map the 8-way output control. And configure the minimum functional unit parameters through the CoE dictionary object, that is, configure the enable / disable status of the module. The user modifies the CoE dictionary object through the EtherCAT master tool, and the system updates the minimum functional unit hardware configuration.

[0081] Optional, user scenario example: 1. Profinet scenario Configuration: Enable the 8DI minimum functional unit and set the de-bounce time to 10ms.

[0082] Process: Modify the value of Record 0x8000:03 to 10. The system updates the GPIO configuration and filters the jitter signal.

[0083] 2. EtherCAT Scenario Configuration: Enable the 8AO minimum functional unit and set the output voltage range to 0-10V.

[0084] Process: Modify the value of CoE 0x8000:02 to 0-10V, and the system updates the DAC chip configuration.

[0085] By mapping the smallest functional unit into a protocol submodule and combining Profinet's Record with EtherCAT's CoE configuration mechanism, efficient adaptation of remote IO's functional modules and industrial communication protocols is achieved, significantly improving the system's flexibility, real-time performance, and maintainability.

[0086] S160: Receive a configuration instruction input by a user, and dynamically enable or disable a specified minimum functional unit.

[0087] In a specific embodiment, it includes: Providing a visual configuration interface, the user selects the minimum functional unit by checking or dragging; Generate the configuration instruction according to the user selection, the configuration instruction including the hardware ID and the enabled or disabled state of the minimum functional unit; Writing the configuration instruction into a parameter storage area corresponding to the industrial communication protocol; Write the configuration instructions into the parameter storage area corresponding to the industrial protocol (Record for Profinet or CoE dictionary for EtherCAT).

[0088] Optionally, the configuration instructions include but are not limited to various instruction forms such as parameterized configuration and interface operation.

[0089] Optionally, develop a visual configuration interface based on Web or desktop applications to support users to manage the functions of the smallest functional unit through graphical operations. The interface mainly includes the following elements: Module topology diagram: Displays the hardware composition of the current remote IO function module in a tree structure or grid layout (such as Slot1: 8DI, Slot2: 8DO).

[0090] Function list: Lists the function types (such as digital input, analog output, counter, etc.) and current status (enabled / disabled) of all minimum functional units.

[0091] Operation controls: Provide interactive components such as check boxes, drag areas, and slide switches to enable users to intuitively select the smallest functional unit to enable.
