I had initially tried using DO3 and BO3 but was using the ID nomenclature - i.e. 10.11.BO3 that I had found in the thread - https://forums.temcocontrols.com/t/programming-for-bacnet-and-modbus-subnet-devices/156.
I changed it to the BACNet instance method and it works - i.e. 199315BO3. Is it safe to assume that the other method has been deprecated?
Sounds to me like DO3 is a typo. BO3 is the correct bacnet object reference.
> I meant 10.11.BO3 doesn’t work but 199315BO3 does work
I noticed that intermittently the variable falsely changes from true to false for about 10 seconds or so. I assume that it timed out waiting for the BACNet read of BO3. Is there a way to not change the variable if the read times out ?
It sounds like a screen refresh issue, run a trend log on the item and see if it jumps around as you describe.
With the example of -
10 TMP = 199315B03
20 IF TMP THEN ENABLE OUT1 ELSE DISABLE OUT1
I see OUT1 turn off intermittently
