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:
1 CAN high CAN-H - Signal for CANopen communication
Pin no. ATV31 RJ45 Comments
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
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.
