Considering the following tag paths where group1 is using real hardware and group 2 is using a simulator where the devices have to be under one channel due to MODBUS port limitations.

(Group 1)  
DvcCh1/Gen1/status/power  
DvcCh2/Gen2/status/power  
vs  
(Group 2)  
DvcCh1/Gen1/status/power  
DvcCh1/Gen2/status/power

What is the prefered method to configure transaction group items and from component values so that they can switch between the two. I believe I can use indirection for the form items (i.e. [source] {1}/Gen1/status/power)? However, I did not see a similar way to do this for transaction group items.

I see you marked this topic as solved. If you’d like, could you share with the rest of the forum how you went about solving it?

Im also trying to figure out how to do indirection on transaction group tags. I cant figure out the syntax. Any guidance would be appreciated.
