Modbus plc vision 130 data reading control and yaskawa inverter

Recommended Posts

Good Morning.
I need help, I'm using plvc vision 130 and I want to read modbus data from a yaskawa inverter, which I haven't been successful with.
I was successful in:
inverter on/off #yaskawa address 0001H
enter frequency #yaskawa address 0002H

Unsuccessful in:
read frequency #yaskawa address 0024H
read inverter status #yaskawa address 0020H

I would like to see in the ihm the value of the bits to use in the application
