Hello guys, I'm learning to work with WinCC SCADA. I manage to enable communication
between WinCC and PLCSIM and I can display PLC inputs and outputs in WinCC project.
However, I want to allow operator to shut down some PLC output. For example PLC program
is a single rung
I can use bit memory M3.0 for example since I can change that value directly from
WinCC project. So when operator on PC click on appropriate button value of M3.0
is changed to 1 and output is forced to zero. I tested this and it works.
Hiwever I'm interested to know if a "real life" problem would be solved in that way?
How thisis done in reality?
Thanks for answer
