You need a professional who knows your PLC and how to interface the signals. The "binary value 0/1" does not exists outside of some software representation, what you need (probably) is some soft of sensor who talks your PLC protocol.The OPC server is a software program that converts the hardware communication protocol used by a PLC into the OPC protocol. The OPC client software is any program that needs to connect to the hardware, such as an HMI] . The OPC client uses the OPC server to get data from or send commands to the hardware.
