For motors I wish they had 3 states, and momentaries, a la old-school Brand H (maybe new-school Brand H, too, I don't know), but yes, GDEVs are better than the several-CIN/COUT alternative. For on-off valves they are great. I now typically use them for generic operator-interface "soft switches" as well, for consistency, and because COUTs do not have configurable state text.

We've been using them form the start, but configured for PLB use. One block gives you the control over the valve and complete status feedback (STAIND), also has nice features for interlocking etc.... Couldn't live without them.....
