Abstract :
Multiprotocol systems have been developed based on field bus technology connected to the university´s LAN. The basic parts are PC and two CAN nodes. The PC interfaces the CAN nodes in the process control laboratory and the computer centre by a LAN. The hardware consists of: development card using Intel microcontroller 87c196, the SJA1000 CAN controller and the PCA 82c250 transceiver. The software to program 87c196 is performed in C and assembler language. The communication between the PC and the CAN node is based on the RS232 serial communication standard. As data server in one case and as remote controller-supervisor in the other, the PC is programmed in the C++ Builder language
