Appendix A.9. Factors Determining the Reliability Property
The Reliability Property of a BACnet object in a Server configuration is determined as follows:

For Multistate Inputs, Outputs and Values, the Reliability property is set to MULTI_STATE_FAULT (9) when the
Present_Value of the object corresponds to an entry in the Fault_Values property of the object, as configured
by the State_Text table in the configuration file.

For all object types, the Reliability property is set to COMMUNICATIONS_FAILURE (12) when the responsible
Server Node is offline.

When neither Condition 1 nor Condition 2 is met, the Reliability property is set to NO_FAULT_DETECTED (0)
