Micro 850 woes

Set up RSLinx Enterprise to browse tags in Micro 850 over ethernet, but the only arrays I can see are reals and dints. Can't see the bool arrays. Anyone know why?
Also, in my FTVME application, if I point to a compactlogix and want to use myDint.0 it will read/write the bit, but if I try doing the same thing pointing to the Micro 850 all I get is ?.

Tim on YouTube does a video explaining explicit messaging between micro 800 and compact logic. I would imagine you map your targets to the data sets and back and for tag manipulation wouldn’t be a problem.
