[41CL] is it recommended to unplug module images during an upgrade?

[Monte Dalrymple]

There is no problem with leaving any image (even the 41CL Update Functions itself or even the OS) plugged in during an automatic update. The FLUPD function never returns to the OS until the update is done so no polling points will be read until the update is done. The same is true for the P8UPD function. If you are doing an update page-by-page manually it will be required to unplug pages being updated because the Flash will be erased as a separate step and that WILL cause problems when polling points are read at the end of a function. No way around that.
