AI Technical Summary

Technical Problem

In existing technologies, the main controller in a PLC system cannot be directly debugged through configuration applications during the field installation and maintenance of the communication module, resulting in low installation and maintenance efficiency.

Method used

By configuring an Ethernet communication channel for the configuration application and the target from the communication module, the target from the communication module receives IP request messages and encapsulates them into asynchronous communication data. The main communication module and the main controller notify the asynchronous communication data through the inter-board bus flag, enabling the configuration application to remotely access the main controller.

Benefits of technology

It improves the efficiency of on-site installation and maintenance of communication modules, reduces communication costs, and enables remote data interaction between configuration applications and the main controller.

Abstract

The application relates to the technical field of the industrial internet, and provides a message transmission method and device between a configuration application and a master controller, equipment and a medium. The method configures an Ethernet communication channel for the configuration application and a target slave communication module, receives an IP request message sent by the configuration application through the target slave communication module, encapsulates interaction data in the IP request message into asynchronous communication data, and informs a master communication module that there is asynchronous communication data through a periodically transmitted data message, the master communication module acquires the asynchronous communication data and informs the master controller that there is asynchronous communication data by setting a bus flag bit, so that the master controller acquires the asynchronous communication data from the master communication module, and the configuration application remotely accesses the master controller through a slave communication module at a remote end, thereby improving the efficiency of field operation.
