Title: Can I read power supply voltage to a DoMore or BRX PLC from a sys variable?
Post by: mfloresh on August 21, 2023, 07:52:05 PM

Hello,

I would like to know if there is a way to read the supply voltage for a DoMore and a BRX PLC from one of the internal system variables. I read in some forums that the battery voltage cannot be read internally.
I know I can do this by simply using an analog input (if one is installed), but wanted to know if there was an easier way.

Thanks,

mfloresh

Battery level is tested by a comparator, so no, there is no analog channel.
