Hello, recently some people in our plant bought a machine with a S7 300 PLC, we are not familiar with Siemens since our standard is AB, when we have problems with this machine is painful to diagnose, even move between blocks into the program, specifically I would like to know two things, first, how to force signals in the STEP 7 program and second, how to find in the program the objects with a "#" at the begining, for example, we have a contact called #stop, but when trying to find its coil I can not because there is a message that says "can not show cross reference for this object" it is frustrating, for me, any help would be apreciated.
P.S. I can not consider a STEP 7 training due costs, so I will have to learn on the hard way.
