This course was created with the assistance of AI tools for narration and visual production. All technical content reflects the instructor’s professional expertise. Engineers learn DCS and PLC — but rarely receive structured training on how the devices talk to each other. Industrial network faults account for a disproportionate share of process plant downtime, and the person who can diagnose them systematically is the most valuable in the control building.
This course teaches the communications layer as it is built and troubleshot on live plants. It covers serial and fieldbus fundamentals, the process and Ethernet protocols, wireless, OPC, and the diagnostic methods that resolve real network faults. The work is anchored in the protocols and standards that define industrial communication: HART and WirelessHART, Foundation Fieldbus and PROFIBUS, PROFINET and EtherNet/IP, Modbus in its serial and TCP forms, and OPC UA as the interoperability layer between OT and IT.
