【 摘 要 】

The paper discusses the overall construction and operational principle of soft PLC. Considering the real time request of the system, we use Linux+RTAI dual core system as software platform. In this platform, the implementation method of soft PLC operational system is introduced. Especially, the design of instruction analysis module is emphasized. On the basis of energy flow concept, the logic algorithm is established, aligning to the left bus. Finally, the system is tested to evaluate the desired control behavior.
