Can't control the frequency Converter via RS 485
Please help me. Can't control the frequency Converter via RS 485 Modbus. ABB frequency converters are easily controlled via ACS_COM_MOD_RU and ACS_DRIVERS_CTRL_STANDARD. I know the addresses of the registers to set the frequency and the command word. With the help PLC firms "ARIES" I controlled frequency Converter. There is open access to "PLC Configuration" in Codesys, and in Automation Builder everything is closed!!!!

Hi Boris
first off all, you need to specify the family type of ABB drives. I don't know your PLC firm "ARIES", I can't help you with this specific product.
Next, you can try to use my app at the follow link for the basics instruction to command one ABB drives via ModBus RTU.

I do not need any complicated actions, I just need to send the command word and frequency to the addresses 8192 and 8193
