Diagnostics on Contact Sensors

[Licourtrix]

I would like to have diagnostics (wire break or short detection) on contact sensors with end of line resistors. I think this can be done by adding an error state on the contact sensor class or modifying the voltage measurement class to act more like a contact sensor. I basically want if
An_input < V1: error (short)
An_input < V2: closed contact
An_input < V3: open contact
An_input >= V3: error (line break)

It there anything existing for this type of thing already that haven't found? If not, I will probably take a crack at it myself but would welcome general direction.

This functionality does not currently exist. It will require the use of analog inputs, instead of digital inputs, as I am sure you're already aware.
