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'.
SINAMICS V20 is a cost-effective, reliable and easy-to-use inverter for basic applications. Features and benefits Single phase input Without filter USS and MODBUS RTU at terminals Wide voltage range ECO mode for Vf and V²f Advanced cooling design Parameter loading without power supply Push-through or wall mounting. 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 Net weight 0.90 kg ( 1.98 lb ) Depth Size Width 150.0 mm ( 5.91 in ) FSA Unshielded 50 m (164 ft) Max. Motor cable length Connections Shielded 10 m (33 ft).
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.
