Abstract
In this paper, the design of the networks system through CAN bus is presented. To distribute the control points with a long distance and different located for the application to on-off electrical equipment by the remote I/O module. The controlling and communication between the PLC and the remote I/O modules are used by the CAN bus serial communication. In this paper, the experiment has been set up the maximum of 32 remote I/O modules. Each remote I/Os are linked to host PLC programmed for handling a interrupt request from any remote I/O independently. Therefore, the scanning time of the controller not effects. By using this technique, the controller(PLC) can be efficiently applied to the several hundred meters.
