I discovered when starting to debug a new program that the ADC display window in Online Monitoring
does not show a value unless that ADC line is read in the program periodically.
I assumed this was raw data for the ADC line and was always shown if there was voltage between 0-5 VDC
even if not called by the program - not so!
The statement in the manual on page 5-4 is not clear that monitor in includes the raw ADC display Online Monitoring monitor values .
I suggest changing the monitor program to display NA instead of 0 in the analog monitor windows for analog line that are "Not Active" (no basic statements referencing that analog line currently) it would aid in debugging.
