    Murphy Interchange Comm Control Module Series The MX4 expansion module provides temperature and frequency input capability to existing and future Murphy Controllers using CANBUS proprietary communications. Modbus® RTU RS485/RS232 is also provided for other communication requirements. Any mix of MX-Series modules can be added to enable Digital and Analog I/O, and Thermocouple functionality for communication and monitoring by the master controller.

  • Page 8: Mx4 Jumper Configuration

    MX4 Jumper Configuration CANBUS: Communication Link to Main I/O Module  LK1: This jumper provides a termination resistor for the CAN communication chain. This jumper must be in place only when the I/O module is the last in the communication chain. See control panel drawings for designation. The cover of the MX4 must be removed to access this jumper link (LK1).
  • Page 9 RS485 Communication Port: Slave Comm. Port. (See Pictorial Above)  LK2: These jumpers provide a termination, pick-up, and pull-down resistors for RS485 communication chain. The PU/PD jumpers should only be in one place on the communication chain. The TR jumper must be in place only when the I/O module is the last in the communication chain.
  • Page 10: Communications

    Communications Physical Layer: The MX4 module features one asynchronous RS232 serial communication port, one asynchronous RS485 serial communication port, and one CANBUS 2.0B proprietary communication port. RS232 Interconnect: The module is equipped with screw terminals called Port 1. This connection is typically used to poll the information for a specific module using twisted shielded pair cable suitable for RS232 networks.
  • Page 11: Mx4 Expansion Module - Modbus Rtu Description

    Communication Address Select Shunts: A jumper shunt header is provided to assign a unique Modbus RTU and/or CANBUS address to each expansion module that may be in the network. This allows the master controller to differentiate between the modules. Addressing is done in binary format, and each incrementing jumper increases the weight by a factor of 2.

  • Page 15 Register 40001 Value Description Register 40,001 is a read-only register. This register holds the model number of the hardware. If you are using multiple Comm modules, it is sometimes helpful to confirm that you are communicating with the expected module type. In this case, it will return 279. Register 40042 Value Description Register 40,042 is a read-only register.
