Abstract
An open PLC control and communication bus was introduced.The communication principle,network configuration and characteristic of the bus were expounded.The specific example of bus application——hybrid control system was given,and communication initialization program was given too.Application result shows that the hybrid control system has merits of complete protection function,rapid communication speed and convenient wiring.
A significance statement is not available in the OpenAlex record.
