Abstract :
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´ .
