    LON Null value

    Finishing up our ENE Lon to Tridium upgrade, and found some nVI points SNVT_count_inc_f (Type 52) that you can use to manual override equipment on off or auto. Problem is on=1, 0=off, and auto in Lon Maker shows a value of 2e+038, which not sure what value to write back. The info on the Count_inc_f says its range is -3.40282E38 to 3.40282E38. Is LON manager truncating the value or is it really 2e+038 which is 200000000000000000000000000000000000000.

    We don't have a copy of Workplace tech onsite to use (the local ENE branch won't sell it to the customer!) and test, so it's kind of hard to confirm exactly how the programs work just by looking at the Visio drawings.

    Hope everyone has a great 4th!

    Thanks

    What happens when you write -1 to it?

    The ENE Workplace Tech program in the MZ treats any value other than 1 as off. Just figured out that I can enter a value as sci notation. Entered 2e+038 as 2E38 in the slot and override is released.

    Even a blind squirrel finds a nut once and awhile!
