    Display and operating elements 5.2 General Description The system controller HE 5750 is the central unit in a CAN based network of the cleaning controller for industrial hose filters. The central control communicates with the decentralised valve control units HE 5724 and the damper control units HE 5740 via the industrial CAN bus.
  • Page 16: Communication Structure

    Communication structure 5.3 Communication structure The central controller HE 5750 is the master in the CAN bus system of the filter controller system. A PROFIBUS-DP or a ModBus interface are available for the process control. Alternatively, a parallel interface for the binary signal exchange is available. However, the complete signal list can only be accessed via the serial interfaces.
