The organizations PLCopen and OPC Foundation combine their technologies to platform and manufacturer-independent information and communication architecture. This mix of OPC UA and IEC 61131-3 creates interesting options for the realization of automation structures. Initiatives like Industry 4.0, Smart Factories, industrial Internet of Things, and others, have communication as key element. This means that efficiency in combining intelligent systems, sensors, and actuators becomes more and more important.

The combined technologies of PLCopen and OPC on the relation between programming languages and communication resulted in 2 specifications:
OPC UA Information Model for IEC 61131-3
PLCopen OPC UA Client for IEC 61131-3
