Hello everyone, I am Liu Lu. Today we will discuss the multi-machine coordinated control of S7-1500 PLCs. This technology allows multiple PLCs to work together, just like a group of friends working together to complete a big project. Whether you want to enhance your factory’s automation level or want to explore advanced techniques, this technology can make your system more powerful and flexible.
1. What is Multi-Machine Coordination?
Imagine you and a friend are cleaning a room. You are responsible for sweeping the floor, while your friend is in charge of wiping the table, but you need to communicate to ensure that the work is not duplicated or missed. Multi-machine coordination in PLCs works on the same principle. Multiple PLCs have their specific roles but can communicate with each other to coordinate actions.
In industry, this approach can:
-
Handle complex large-scale systems -
Improve system reliability (one failure won’t cause the entire system to crash) -
Facilitate system expansion and maintenance
Note: Multi-machine coordination is not simply about connecting several PLCs together; it requires careful planning of each PLC’s tasks and communication methods.
2. Hardware Connection: Let the PLCs Hold Hands
To achieve multi-machine coordination, the PLCs must be able to
