Hello all.
I have just recently got a S7-1200 F CPU and safety licence and I am trying different things. So far I've tried monitoring of emergency stop and safety doors. Today I have tried to implement a two hand control function, but I have some problems.
This is the wiring that I have done between the two hand station and the PLC(see the attached picture)
But it's not OK because the digital inputs are always ON, they don't turn off when the buttons are pressed. But I think that they shouldn't be on in the first place...
Should I try to connect 1 of the two and control station to VS1 and 3 to VS2?
Any ideas on how to solve this issue?
Cheers
Aleix
