Communications and PLC Network Systems

Course Code: ELEC 323

Academic Year: 2025-2026

The course deals with the communication between computers and programmable logic controllers and between programmable logic controllers for system operation and control. The function of and operation of reading and writing between PLCs for use in industrial applications is analyzed and implemented. Communications between PLCs and computers through serial communications, data highways and the ethernet with various programming techniques will be addressed and applied with reference to IEC 61131-3 programming standards. Programming with discrete and analog signals will be implemented. Communication and network details of a DeviceNet Network will also be covered in this course. Programmable logic controllers to be studied are Allen-Bradley Compact Logix and SLC series, Omron CJ1M.
