I use my drive in a Modbus network. When I try to parametrize the drive or program or monitor the built-in PLC, there are communication errors. How can I connect to the drive and PLC?
In the C2000 series, you can remove the keypad and the gender changer behind it. Then use the RJ-45 port behind the keypad. It has a separate RS-485 transceiver, and the Modbus network can work normally.
The keypad port uses the same node addresses as the other RJ-45 ports, but with fixed communication settings. So you need to set the communication driver of your PC to RTU 19200, 8, N, 2.
MS300 and MH300 come with a USB port, which you can use without interfering with the Modbus communication on the RJ-45 port and SG terminals.
