Modbus TCP write

Trying to send values to a Eurotherm temperature controller via modbus TCP. I can read values, but when writing I get a “no valid data” error.


Are you seeing any other errors in the transaction monitor? What function codes are you using?


No other errors. Right now I am just writing values to one unit. I am successfully reading values from 14 units though.

Hello @Dmorr,

Just wanted to check in and see if you were able to finish up your set up.
