Hello everyone,
Sinamics V20 Modbus Register Code
The SINAMICS V20 inverter has been designed to be protected by fuses; however, as the inverter can cause a DC current in the protective earthing conductor, if a Residual Current Device (RCD) or Residual Current Monitoring Device (RCM) is to be used upstream in the supply, the device must be of type B. USS, Modbus RTU Compliance with standards CE, cULus, C-Tick (RCM), KC EN 61800-5-1 /EN 60204-1 and EN 61800-3 Standards Communication Communication. Data sheet for SINAMICS V20 MLFB-Ordering data Figure similar Mechanical data 145.5 mm ( 5.73 in ) Degree of protection IP20 / UL open type 90.0 mm ( 3.54 in ) Height.
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'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.
