RESEARCH ON DUAL PLC SIMULATION TECHNOLOGY BASED ON MODBUS TCP COMMUNICATION
View through CrossRef
With the rapid development of industrial automation technology, efficient communication between PLCs has become the key to realizing complex control systems. Based on the MODBUS TCP protocol, this paper studies the simulation method of dual PLC communication, aiming to improve the reliability and real-time performance of industrial control networks. By constructing a dual PLC communication simulation platform based on MODBUS TCP, the data frame structure and communication mechanism of the protocol are analyzed. The logic design and communication configuration of the PLC program are implemented using TIA Portal software, and the simulation platform adopts S7-PLCSIM Advanced. The experimental results show that the simulation system can stably realize data exchange between dual PLCs, providing a reference for multi-PLC collaborative control in industrial fields. This research provides theoretical support and practical basis for the application of MODBUS TCP in industrial automation.
