Hello
One more quick question. I am using FB to program my PLC. On the first FB "EN" pin on the left hand side of the FBD I currently have a switch wired in with a constant logic 1 so that the FB's in series are Enabled.
is there any way of specify a logic 1 constantly instead of having to wire a 1 signal. I have tried typing "True" on the EN but the plc wont accept it. From using a S7 200 I remember there was a contact called "SM" something that always closed when the PLC was put into run mode. I cannot remember the exact address if anyone can tell me it would be useful
thanks
