splatch opened a new issue, #1234:
URL: https://github.com/apache/plc4x/issues/1234

   ### What happened?
   
   Modbus unit id is part of every frame which is being exchanged through TCP / 
UDP or serial port. It means that this parameter is not needed for connection 
negotiation. It does not need to be set prior connection establishment. It 
might remain as a connection level default, for shortening tag definitions for 
basic applications.
   
   Given that there are inverters which support multiple unit ids for different 
modbus register tables current way of managing unit identifier requires 
starting up multiple TCP (or even worse) - serial connections.
