(English Abstract)
PLC is a hard real-time system that repetitively reads inputs and computes and writes outputs. PLC is used to implement various control logics required for manufacturing processes such as assembly lines and robotics. PLCopen OPC-UA defines the information model that expresses the variables and methods in the PLC software to external industrial devices. It also defines the function blocks that PLC uses to access external OPC-UA systems. This paper proposes a PLCopen OPC-UA framework that includes information model generation and OPC-UA client function blocks. In order to accomplish this, we extended the open source software, Beremiz and OpenOpcUa, and implemented the OPC-UA server and client functions. Through experimentation, we confirmed that the developed system generates an information model conforming to the standard and shows stable and predictable performance while satisfying the real-time constraints of PLC.
