Action
Check the channels for which A/D conversion is enabled in the parameter
setting of GX Works3. If A/D conversion is not enabled in any channel, enable
A/D conversion for 1 or more channels in the parameter of GX Works3 or in
the program.
Remove the cause of disconnection by replacing the analog signal cable, etc.,
and then check the digital output value.
