RedLion accessing SLC500 Timer Status

[joeboucher]

I'm trying to program a RedLion Graphite HMI to access the done bit from one of the timers, using the DF1 driver. I see that I can access the status word, but cannot select the bit within the word. I also do not know which bit numbers, within the word, correspond to the DN, EN, and TT bits.

Any clarification will help. Thanks.

I just realized I was using an integer instead of a flag tag, but I still do not know the bit order of the tags.

I didn't know you could poll the status word. I have always just polled the bits.

T4:0/DN = Done Bit
T4:0/EN = Enable bit
T4:0/TT = Timing Bit
T4:0.ACC = Timer's Accumulated Value
T4:0.PRE = Timer Preset
