Sinamics V20 Modbus Register
Hello everyone,
I'm trying to use an arduino Duamelinove to comunicate with a Sinamics V20 inverter via RS485. I have a shield to convert the RS232 from the arduino to the RS485 from the inverter. I also have a RS485/USB adapter to monitor the communication from a computer.
Motor Braking module Resistor SINAMICS V20SINAMICS V20 feature Your benefits The dynamic energy is dissipated as heat in a braking resistor with an adjustable duty cycle of between 5% and 100%. Possible to use dynamic braking to increase braking performance. Inverters ≥ 7.5 kW have an integrated braking module.

SINAMICS V20 basic converters 0.12 kW to 30 kW (0.16 hp to 40 hp) SINAMICS V20 basic converters 3 Overview SINAMICS V20 converters, frame sizes: FSAA, FSAB, FSAC, FSA, FSB, FSC, FSD and FSE SINAMICS V20 – The cost-effective, reliable and easy-to-use converter for basic applications Today, in an increasing number of applications in plant. Modbus SINAMICS V20 Standard library The communication port is available at terminals. The preset parameters of the USS and Modbus RTU are defined in the connection macro. N Easy integration into existing systems and micro-automation systems n Easier commissioning through standard.
I've loaded the SimpleModbusMaster library example on the arduino, and I'm getting transmission errors on the computer monitor (values different from what was transmited). The inverter receives the signal, but it returns a 'parity error'.
I also tried communicating the inverter with the computer, without the arduino, using a Modbus Master demo and, this time, it returns a 'character structure error'.

Has anyone ever tryied to do something similiar before? I'm not sure if this is even possible as everything I find online mention only communication between Siemens Inverters with Siemens PLCs.
Any thoughts would be appreciated.
