The Rpi has a serial port built into its GPIO connector and I have built an interface that would allow serial connection between the Rpi and the PLC. The Application server needs a ethernet Modbus TCP/IP interface. Although developed by the same organization, OPC UA differs significantly from its predecessor, Open Platform Communications (OPC). The OpenPLC project was created in accordance with the IEC 61131-3 standard, which defines the basic software architecture and programming languages for PLCs. Profinet (usually styled as PROFINET, as a portmanteau for Process Field Net) is an industry technical standard for data communication over Industrial Ethernet, designed for collecting data from, and controlling equipment in industrial systems, with a particular strength in delivering data under tight time constraints (on the order of 1ms or less). The PiCAN2 CAN Bus interface board uses the highlighted pins on the Raspberry Pi's 40-pin header. Updated source code. I have not tried this out yet. Registered in England and Wales. 5Beremiz and Beremiz_service connectors To connect a PLC, Beremiz provides 2 types of connectors : •a Pyro connector •a WAMP connector.
