What causes an AEConfigErr Alarm for SignalInBool Object?
Just curious if I configure the AEConfigErr = 1(alarm) for a SignalInBool object, what does the system look for to detect an error?
For an analog object if I set the AEConfigErr = 1 and lift a wire in the field, then I get a signal error/AEConfigErr alarm.
How does this work for a digital input for example to a dry set of contacts? Will I get a signal error if I lift a wire? If so, how does is know the difference between an "open loop" and when the contact opens?
I realize I'm asking multilple questions but just looking for a basic understanding for what conditions for digital inputs cause the AEConfErr to go into Alarm.
Today I'm working on a PM861 with a DI810 module but beleive the answer would be true for most controllers and DI810 or DI840 or DI880 modules.

DI810 shows a channel error (AEConfigErr = 1)only when +24VDC is not connected on terminal board pins L1+ and L2+
If you need some loop control on digital input you have the DI890. With this card you have cut and short circuit alarm using two resistors near field contact.
