Henning is correct in that the priority array is backward.

a ’1′ priority is higher than a ’16′ priority….

It's explained well in the text, just the word in the diagram is wrong. Thanks for this site! In the first figure the priority array should go from highest to lowest, not from highest to highest.

During our support work for many customers with many systems we have not seen a situation where someone produced such information so we assume that no one has implemented it.

We have a software tool, which is provided with the CAS Bacnet explorer – Call the CAS BACnet Watchdog that monitors traffice aimed at a particualr device or object and keep a record of time and source and command. Contact us for details.

I mean - is there a corresponding array that get filled in with the device instance ID or something like that eadh time a priority is commanded ? How do you know who commanded/wrote ?
