Hey guys,

 

Is anyone aware of a way to read low bus voltage on the PLC.

i.e. PLC is still powered, but PLC io blocks have lost voltage?

Obviously I can feed this voltage into an input to see when voltage is removed, but is the a status register somewhere that will accomplish the same thing?

Cheers

Duncan

Hi Duncan,

you could use WcState or State for a general error that will occur when remove voltage.
