Modbus tcp Slave several addresses

[TomasD]

Can you create multiple Slave addresses (Example: 1, 5,12) with different registers?

Is the Codesys device acting as a slave in this case? If so, are you trying to add multiples underneath the same Ethernet device?

[bjornidar]

If you mean running one physical slave configured as “several slaves” in the master, I’ve achieved this by using different ports (502, 503, …) in the slave.

Do I understand correctly that from the codesys configurator I will not be able to make multiple devices? With the ports, I liked the version.

You may be able to do the same with the Configurator with individual Slaves, each with their own Port:

You can simple add more under your ethernet device and assign different ports.

NOTE: I have not tested this but it should work similar to @bjornidar.
