Invalid Priority array index with a Priorty 6 command on a boolean writable point........What the hell........

American Auto-Matrix controller?

JCI FEC2620 REV 5.3 and 3.6.47 J700 Sorry didnt think about that information..........

Priority 6 is used for min/on and min/off times on a boolean writable point. I've seen a post on niagara-central about a certain AAM controller not accepting writes at priority level 6. Sorry, JCI is not my cup of tea.

Thank you

Yeah, those FEC's do some funny stuff with the points sometimes. Just because you have points exposed in CCT to Bacnet, doesn't always mean you can write to them even if you drag them into the tbox as writable like the occ/unocc/standby setpoints in the ZN-T Setpoint Determination block. You have to create new Network Inputs and connect them to the points you want to actually write to. It can be a real PITA sometimes especially if you have already written a whole bunch of caf files and then tweaked them or their setpoints in different units.

If its a writable point that isnt connected to a network input, map it in as a relinquish default not its present value.

I did find out when dealing with those points in the ZNT setpoint determination block you can not connect them to the present value but the property id is actually 3113.
Not just those either, any point in CCT that is exposed and is not connected to a network inout to change them...Setpoint miscellaneous column

It apperas that just as with the auto matrix described earlier that they will not accept priorty 6 commands so i went into the slot sheet and made priorty 6 disappear...

BTL certified devices are checked to ensure that they follow the BACnet standard. If a controller accepts a write at priority level 6, it will fail the BTL certification test.

I learn something new every day. Thanks for that. You probably just saved me hours of my life.
