In the settings field - what I see when I change the device ID: ‘are you sure you want to change the mod-bus ID’? My questions are:
1- Is this field only used for Mod-bus?
2- When on a network with multiple T3s, do the ID #s need to be unique?
3- Does Bacnet care about this ID#? My guess is no.
4- Is there a ‘best practice’ for this ID field?
The reason I dug into it is because I have a site where the BVs stopped working and yet YABE shows that the Bacnet points are working. I was using the device address (ie. 13BV20, 14BV20, etc…) which used to work just fine for all 8 controllers on the network. So, I changed to using instance #s and I got all but 2 points to work (one BV per panel). The analog points still transfer using the device address: 13AV4, 14AV4, etc…
I have updated all software/firmware for said devices.
I browsed the help docs but didn’t see the Device ID explained, however, I may have missed a reference to it when reading through the help docs.
