Added current communication for Siemens PLC200
Thread Content
There is a set of PLC 200s, and the communication has been established. But there is no current; I want to add current communication on this basis. How should I do this? I’m not very familiar with PLCs; I hope everyone can provide a detailed set of steps
What does it mean to have no current? I don’t understand
What systems does the 200PLC communicate with? What does adding a current communication mean? Poor description
Sigh, I guess guys from science and engineering fields often fail in language courses; their expression skills are really poor. Are you acting as a master or a slave with 200? Is it about adding a current communication to the DCS over a distance of 200? In this communication system, the communication points are stored in area V; projects generally have a backup storage area as well. You just need to assign a value to VW or VD for the corresponding area.
Haha, the senior’s advice is correct. It’s a communication to the DCS; since it’s communicating with the DCS, then the DCS must be the master. Just assign it directly within the program to a vm or vd, right?
