Abstract

When a PLC (programmable logic controller) and microcomputer communicate in real-time systems, the technique of real-time communication between PLC and microcomputer is used in many areas. This paper researches the technique and solves the real-time communication problem between the PLC and microcomputer. We use the OMRON PLC and C++ program language, and use the example of real-time communication between PLC and microcomputer in control of a microwave transmitter to illuminate the basic means and technique in real-time system design and communication software design, including the core technique of real-time communication. This proves the validity and the value of this technology.
