In this paper, the authors discuss a control system model which has four access layer servers connected to several loads via four Controller Area Networks (CANs), and these loads are controlled from those servers or virtual interface machines. The system network involves interconnection of access layer servers (e.g. laptops), Ethernet controller (which establishes a Local Area Network, LAN), and CAN controllers. This paper can be implemented in the control of industrial processes in a real-time. In this work, the Programmable Logic Device (PLD) of the Ethernet controller which is its intelligent Application Specific Integrated Circuit (ASIC) was replaced with a programmed AT89C55 microcontroller to achieve the same switching logic.
