Niagara AX- How do you write a boolean value when a device comm goes down?

[droptchevy]

Im looking to create some logic if someone shuts the power off to one of the chillers. Since it will not see a actual alarm from the chiller i want to switch over to the other chiller when the comm goes down. Seems like it should be pretty easy but i could not get anything to work.

Also what are you guys using for rolling average blocks? I want take multiple snapshots of a value over a period of time.

You could use a StatusDemux in KitControl

Check out kitControl/Util/StatusDemux.

Part 2 there is a Numeric Delay that maybe what you want. There is also an average feature in the History Chart Builder that sets duration and average under the rollup line.

Thanks guys you both solved my issues.

... switch over to the other chiller when the comm goes down. ...

build a ProgramObject ..... add a property (health) of type driver:PingHealth

then ... boolean b = getHealth().getDown() ;

make a link from yourDevice/health -> yourProgram/health
