Post by kislov on CODESYS Modbus 4.4.0.0 - Modbus network redundancy ^{CODESYS Forge talk (Post)}
Hi. There is next information in CODESYS Modbus 4.4.0.0 Release Notes: "Modbus network redundancy" How to use this feature? As I understand, new fields in STUCT ModbusTCPComSettings are associated with it, but more detailed information is needed.

Post by ofey on Modbus TCP communication ^{CODESYS Forge talk (Post)}
Hi! I tried setting up the PLC I'm working with (Beijer GN-9373) to connect to a modbus master running on a laptop. I have an ethernet connection (via USB-C to ethernet) between the laptop and the controller. I have tried following tutorial on how to set this up. I have added an ethernet device with the IP-address of the PLC. Further I added a ModbusTCP_Slave_Device with default settings. I get the error "Failed to open TCP Port: 1" when I try to go online with the PLC. Earlier I tested the exact same set up with the soft PLC from codesys. I can then read/write values correctly with the Modbus master i have running on the laptop. Hope anybody can help me with this, thanks in advance!

Guess you could just add two modbus slaves with the same ip, to enlarge the 10 channel limit.
