The PLC is SIemens Series 414. I have aproblen in forcing some vaiables.
In order to force the variable I make a Vat,then entering the variable address and new/modifid value but the Force option is not active.for example I have a variable suchas
B3.DBW12 and I want to assaign a value to it.
It is noted that when I enter the address, it will bocome red,indicating that the address is not correct.
I would greatly appreciate if someone can help me.

Vahid
