IEC_BACNET_RELIABILITY (ENUM)¶

TYPE IEC_BACNET_RELIABILITY :

Describes the reliability of the main value from an BACnet object.

This enumeration, of type BACnetReliability, provides an indication of whether the Present_Value or the operation of the physical output or object executed actions in question is “reliable” as far as the BACnet Device or operator can determine and, if not, why.

InOut:

Name	Initial	Comment
_RELIABILITY_MAX_SIZE	16#7FFFFFFF
RELIABILITY_NO_FAULT_DETECTED	0	The present value is reliable; that is, no other fault has been detected.
RELIABILITY_NO_SENSOR		No sensor is connected to the Input object.
RELIABILITY_OVER_RANGE		The sensor connected to the Input is reading a value higher than the normal operating range. If the object is a Binary Input, this is possible when the Binary state is derived from an analog sensor or a binary input equipped with electrical loop supervision circuits.
RELIABILITY_UNDER_RANGE		The sensor connected to the Input is reading a value lower than the normal operating range. If the object is a Binary Input, this is possible when the Binary Input is actually a binary state calculated from an analog sensor.
RELIABILITY_OPEN_LOOP		The connection between the defined object and the physical device is providing a value indicating an open circuit condition.
RELIABILITY_SHORTED_LOOP		The connection between the defined object and the physical device is providing a value indicating a short circuit condition.
RELIABILITY_NO_OUTPUT		No physical device is connected to the Output object.
RELIABILITY_UNRELIABLE_OTHER		The controller has detected that the present value is unreliable, but none of the other conditions describe the nature of the problem. A generic fault other than those listed above has been detected, e.g., a Binary Input is not cycling as expected.
RELIABILITY_PROCESS_ERROR		A processing error was encountered.
RELIABILITY_MULTI_STATE_FAULT		The Present_Value of the Multi-state object is equal to one of the states in the Fault_Values property and no other fault has been detected.
RELIABILITY_CONFIGURATION_ERROR		The object’s properties are not in a consistent state.
RELIABILITY_RESERVED_11		Indicates that the group includes one or more Status_Flags properties whose FAULT flag value is equal to TRUE.
RELIABILITY_COMMUNICATION_FAILURE		Proper operation of the object is dependent on communication with a remote sensor or device and communication with the remote sensor or device has been lost.
RELIABILITY_MEMBER_FAULT		Indicates that the set of referenced member objects includes one or more Status_Flags properties whose FAULT flag value is equal to TRUE.
RELIABILITY_MONITORED_OBJECT_FAULT		Indicates that the monitored object is in fault.
RELIABILITY_TRIPPED		The end device, such as an actuator, is not responding to commands, prevented by a tripped condition or by being mechanically held open.
