The timer preset and the counter setpoint show as ?. Those two values
are not recovered from the file yet, so RungLens marks them unresolved instead of printing a

plausible guess. Rung comments are not extracted yet either.

.L5X, you do not need this.CtrlLens previews and compares .L5X files for free, and it is good.
If that is the file you have, use it. It runs offline too, and its .ACD
conversion is free as well.
RungLens exists for one case: you have an .ACD, and you do not have a
Rockwell licence. CtrlLens converts .ACD by calling Rockwell's Logix
Designer SDK, which means Windows and a Studio 5000 installation. If you had that, you would
not be here.
