Sending a tara command via modbus Write Multiple holding registers

[labviewette]

Dear Community,

I am trying to send a tara command via modbus to a WTS scale from Bosche. The company itseld uses modbus poll as a tool to communicate via modbus. The device supports only writing to multiple registers (16). I am successful in sending the command with modbus poll (s. Attachment). Nut not succeful with LabVIEW. I have attached a snippet of the LabVIEW code.

The error i get with LabVIEW is: Modbus Error: Illegal Function. This function is not implemented on the server.

Dear Community i have solved the problem by myself 🙂 I needed to send the adress 5 rather than 6 because register number and adress are not the same.
