interlock
Member
Dear All,
Consider a selector switch is located at the electrical panel and it is wired to the PLC at I0.5 (When I0.5 is low = Manual , when I0.5= high = Auto).
Also, WinCC has configured the touch panel with a button authorizing selection of Manual and Automatic.
How to make sure the safety? Just by providing interlocks in the program???
What is normally done or what is the normal practice when programming such applications?
PLease bear with these "low-level" questions .... I'm still getting on with WinCC Flex.
Regards
