What is the pin-out of the RJ45 socket of an ATV31 for connection of Modbus, CanOpen and PowerSuite cables

     The RJ45 socket of the ATV31 can be used for connection to the following networks and accessories:

     a PLC via a Modbus bus or via a CANopen network
     a PC/laptop loaded with PowerSuite software
     The VW3A31101 remote display terminal

     The Pin out of the RJ45 socket of the ATV31 is as follows:

     Pin no.                            ATV31 RJ45                         Comments          

        1                                       CAN high                           CAN-H - Signal for CANopen communication 
        2                                       CAN low                             CAN-L - Signal for CANopen communication 
        3                                       CAN GND                          CAN-GND - Signal for CANopen communication 
        4                                           D_B                               Signal for MODBUS communication 
        5                                           D_A                                Signal for MODBUS communication 
        6                                            NC                                 Not used 
        7                                          10 Volts                           0-10 V voltage supplied by the ATV31 which can be used to supply the 

        8                                           0 Volts                            converter when connected using PowerSuite software


    Important clarification

   For Modbus communication, the signals used for the ATV31 are D-B and D-A only -  the other connections are not used.

   For CANopen communication, the signals used for the ATV31 are CAN-H, CAN-L and CAN-GND -  the other connections are not used.

   With the VW3A31101 remote display terminal, the signals used are D-B and D-A as well as the power supply.

  Caution: Lengths of cables need to be observed as too greater voltage drop in network connections may cause a malfunction.
