It doesnt seem to work. The code compiles well but I dont think it actually stores them. Do you know of any other libraries that can store in registers to modbus tcp?

Its a field agent that does this. The field agent reads the registers of the arduino or should read it if the arduino is configured properly

what software is used by field agent? some modbus clients offsets are 1-based, so a register configured as 100 in library should be 101 in this software.github.com/andresarmento/modbus-arduino/blob/master/README.md
