Hello - I'm sure this is a total rookie error
...but i've racked my brain and logged off/on, cycled power, substituted my final ladder program with a simple 1 input and one coil program with no luck.
I'm using a SG2-20HR-D. my ladder program is not very complicated i'm using a number of inputs and timers (mode 3, off-delay) to set coils Q01-Q07 for specific periods of time.
I cannot get the coils to set at all. I can link up and go online and RUN just fine. the inputs, when changed (via switches) register correctly as i switch them. but the output coils Q01-Q07 AND Timers are not setting or counting.
In simulation mode, all the logic and timers work swimmingly. but when connected to a live PLR....NO WORKY!
Any wisdom from some of you veterans of the SG2 would be greatly appreciated.
Thanks in advance

P.S. i've attached the file in case...
