Hello everyone,
Sinamics V20 Modbus Address
Page 142 Communicating with the PLC 6.2 MODBUS communication Mapping table The SINAMICS V20 inverter supports two sets of registers (40001 to 40062, 40100 to 40522) as the table below shows. 'R', 'W', 'R/W' in the column Access stand for read, write, read/write.

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.

I also have a RS485/USB adapter to monitor the communication from a computer. I've loaded the SimpleModbusMaster library example on the arduino, and I'm getting transmission errors on the computer.
- With its compact SINAMICS V20, Siemens offers a simple and cost-effective drive solution for these types of applications. SINAMICS V20 sets itself apart with its quick commissioning times, ease of operation, robustness and cost efficiency. With seven frame sizes, it covers a power range extending from 0.12 kW up to 30 kW (1/6 hp up to 40 hp).
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.
