that are connected to the onboard UI pins in the controller.
All such sensors are monitored by the controller for out-of-
range/invalid values.
Lon Network Communication Errors: These errors can
occur for Lon NetworkVariable Inputs that are bound to other
controllers when the source controller fails to send the
data.The controller tracks and reports network communication
errors for the following list of NVs when they are bound:
Control Alarms: These are application specific alarms tracked and reported by the controller.
