[?]:s5-90U "Function identifier in IF unknown"

Post by kriztof » Wed Apr 22, 2009 10:24 am

Hello
When I try to force outputs in my s5-90U I get message
"Function identifier in IF unknown".
What does it mean?
I follow instructions from manual.

It looks that S5-90U doesn't support force outputs function. Perhaps when Step5 calls force function, PLC can't recognize this command and returns error. Well, I'd like to know it for sure.
