- The 32 percent smaller size FSAD with cabinet dimensions of 176.5 x 136.6 x 158 mm makes the Sinamics V20 an even more flexible and space-saving solution. The Sinamics G120C frequency converter also features excellent flexibility. Thanks to the new arrangement of the plug connections, in future there will be more space in the control cabinet.
- 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 n Easy integration into micro automation systems n.
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.
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.
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.
