    ABSTRACT: One of the basic goals when considering networks for communication in industrial control applications is the reduction of the complexity of the related wiring harnesses. In addition, the networking offers advantages for industrial control applications, such as ease of cabling, ease of changes in the cabling, ease of adding controller modules, etc. CAN (controller area network) is generally applied in car networking in order to reduce the complexity of the related wiring harnesses. These traditional CAN application techniques are modified to achieve real time communication for industrial control applications. In this paper, we design a special purpose scheduler on CAN for a real-time network system. This scheduler can be used to schedule messages in DCS (distributed control system) with CAN for real-time network systems. Also, the real-time network system is developed and the proposed scheduler is verified experimentally

    ABSTRACT: In case of the speed synchronization for multi-motors, the real time data communication is necessary. In order to satisfy this requirement, the complex signal lines are usually used to detect each motor speed and to command the desired speed. Such a traditional implementation technique induces many problems in the view of reliability and economy because of the amount and complexity of wiring, noise and maintenance problems. These problems are serious especially when the motor controllers are separated widely. In this paper, we propose the simple synchronization system with the aid of serial communication using the controller area network (CAN) to overcome these problems. CAN is generally applied in car networking in order to reduce the complexity of the related wiring harnesses. These traditional CAN application techniques are modified to achieve the real time communication for the multi-motor control system. Also, the speed synchronization technique is developed and the proposed methods are verified experimentally
