This assumes that the current position information is somehow stillvalid,at least approximately. However, tehre is no guarantee taht this is so If one has such things on that particular device.
Yes, but, *almost*. You have no way of knowing whether anybody has moved anything while the IOC was off. Somebody may have taken the whole thing apart and put it back together in which case you really won't know where anything is. Case in point (in a somewhat roundabout way): we had a device where moving parts would have been able to run into one another if that hadn't been prevented in software. One of the mechanisms broke, and I was asked to put that one mechanism (one of 3) into simulation. The software was written such that it didn't let me do that without basically rewriting it, which I didn't, so it was "either you can have all of these in simulation or none". This included datuming (homing). Aloha, Maren
