Data not write in modbus

flows (3).json (7.7 KB)

Please see my attached flow and guide where I did mistake.

When I write data into Modbus server through inject node then it write on Modbus server,
But when I try to write data of MQTT then its not write on Modbus.
Both have same output Format(msg.payload : array[51])

Add a debug mode showing what you are sending to the server node. Click the inject node and then trigger the mqtt input and show us what you see for each case.


both have same data format

Yes, but debug 307 has completely different values!

All Modus data is 16 bit & therefore 65535 is the MAX value permissible

yes got it thanks.
