S7 Ladder Monitor

Hi,

When I'm monitoring an S7 program (in this case a S7300 PLC), I seem to have difficulty in getting items to display properly.
In the attached screen shot I can't get the current values for the "ADD_DI" to display. I've tried clicking in and around the instruction, but it just stays black.

Does anybody know of a way around this or am I just missing something really obvious?

Thanks,
Matt

Either set M101.1, M101.2 and M101.3 to True, or use a VAT to view the values of MD21, MD210, MD214, MD218

Think you won't see the values in LAD since the enable is False.

That does seem to be the case.
Thanks Jeebs.
