this is a hardwired ladder diagram using standard symbols..i am trying to get this same function on a plc...more specifically a siemens s7-1200 1212c ac/dc/rly plc, using TIA portal v13 software... if anybody can help me in the way of configuring a timer to work as a normally closed timed open timer that would be awesome. or if there is just a simpler way of doing the whole thing let me know.View attachment two hand safety circuit.pdf
