Hi all,

Im working on Different modbus Energy meter , how to link different Energy meter Modbus system datas into a single flow.  
If i put 2 modbus flex getter in single flow of different modbus , either of those are working , While combining both together im not getting any response.

can anyone give a solution for this issue .

Appreciate , if some one help me in resolving it

Can you show us your code ?

What energy meters are you talking to ?

Are they both on the same bus or do you have multiple Busses ??

Its working in different flows.

Can i get both in different modbus same flow ?

Usually you would paste your code inline rather than upload it.

Have you tried taking out the UnitID from both of the Flexgetter nodes ? You are setting it in th function node so i am not sure if this will give you problems.

Just confirming that if you have both of thes active in different flows they will work with no issues ? It is only when you add them both to a single flow that you have the issue ?

Are you getting an error ?

The help for the FlexGetter suggests adding a catch node to see what is happening.
