Greetings,
I am designing a system (B) which must receive a signal from an outside system (A). When the signal is sent by system A, system B needs to toggle a PLC pin from TTL high (5V) to TTL low (0V).
The supplier of system A has told us that they will provide a "potential-free contact". They have also told us that this could be NO or NC.
Since system B needs to toggle a PLC pin, my questions are:
-How can we receive this signal from system A & toggle the PLC pin?
TIA
Charlie
