Multi-bus PLC configuration method and system, electronic equipment and storage medium

Abstract

The invention provides a multi-bus PLC configuration method and system, an electronic device and a storage medium, relates to the technical field of PLCs, and is used for controlling logic programming software of a master PLC to add management objects corresponding to the types of buses, and aiming at slave PLCs connected through a target bus, the management objects corresponding to the types of the buses are added in the logic programming software of the master PLC. The master PLC performs data interaction with the slave PLC through the following steps: a management object corresponding to a target bus forms task information matched with the master PLC in format based on received task information and stores the task information in a PLC memory bus cache space corresponding to the target bus; and when the PLC runs, the software carries the I / O data in the PLC memory bus cache space and the PLC memory I / O data cache space corresponding to the target bus according to a task period and a task rule, so that data interaction between the master PLC and the slave PLC is realized. The method and the device are used for realizing integration of different bus devices and are high in efficiency and low in development difficulty.
