The RS-485 adapter has a feature that allows you to override the modbus unit address on incoming modbus requests. It’s very convenient and I use it to avoid having to change the factory-default modbus addresses on modbus hardware.
However, you can only input one translation address, so I can’t figure out a way to use this feature when I have several devices daisy-chained on one RS-485 adapter.
What I’d like to be able to do is override multiple addresses. So for example, I could set the adapter to receive modbus traffic on ids 1 and 2, but translate them into ids 7 and 254, which are the factory-default modbus addresses of the modbus devices I’m using.
Is there a way to accomplish this?
Thanks for any assistance!
