摘要

This Paper analyzes the structure of serial industrial fieldbus such as RS485,CAN and agreement stipulations of MODBUS and CAN2.0. It expounds the new PLC synchronous control method based on a serial bus between each module, control strategy of the synchronizing time examination mechanism, pre-synchronizing information processing and ‘free synchronization’ and ‘forced synchronization’ .
