Issue:
Which Modbus function code used by the WRITE_VAR function communicating over Modbus/TCP?

Product Line:
Modicon Controller, eNOC, ETY modules

Environment:
All

Resolution:
The WRITE_VAR function block over Modbus/TCP is using Modbus Function Code FC16. Even if you want to write a single register using WRITE_VAR it will be going to use FC16.
