How to read modbus frequency inverter status

Recommended Posts

I succeeded in writing frequency data to the yaskawa drive for speed change.
but I was not successful in reading the status bits from Run,Ready...and others.
Could you give me a hint on how to read these bits? this drive does not mention read bits,coil but only registers.

how to read individual bits and show on display.
I'm using a mink 130.

Thanks for any help, no idea how to do it

For writing I used this FB

3 horas atrás, kratmel disse:

Você deve tentar ler dois bytes de status do VFD. Melhor maneira - leia-o via PC para teste.

Em seguida, use o mesmo comando modbus no PLC.

Você pode usar a função "numérico para bit" para converter os bytes de status do VFD em um vetor de 16 bits no PLC.


obrigado pela ajuda vou tentar fazer

Estou fazendo um teste e não entendo porque colocar os quatro mbs em 1 não deu um total de 15

#EDIT: nevermind, already found the issue
