Hi, pawas
It's not possible to communicate two XBTGT with M340 using Modbus RTU.
In your case XBTGT acts Mater role, but in Modbus RTU network could be only ONE master. So, if you want to use two XBTGT panels with one M340 controller you should use Ethernet network (Modbus TCP protocol).
In this case your panels will be clients and your controller will be server.

thnx

but in the manual it is clearly mentioned that 32 xbtgt can be configured in one modbus RTU network where XBTGT will be act as a slave.

but with XBTGT as a slave and M340 as a master is not getting communicate.

plz clarify it.
