Hello!
I just finished reading "MODBUS APPLICATION PROTOCOL SPECIFICATION V1.1b3" and "MODBUS over Serial Line Specification and Implementation Guide V1.02". I was expecting to find something about my question, but I didn't.
I intend to build a system that has a client and several Modbus RTU servers on the same network.
Each of the servers would leave the production line with a fixed address (I'm not talking about data addressing).
How this could be handled by the client (several servers with the same address on the network)?
I couldn't find anything in the docs about this. Is there a common approach? Where can I read more about this?
A solution would be to use a dip switch in each server. This solution isn't ideal because the addressment is manual and it increases production costs.
Is there some way I could do this using Modbus (and still respect all protocol rules)?
Thanks!
