Reference Input Point Operation If the reference input point reads values from an internal referencing plant, the
original datapoint value of the input will be taken.
If the reference input point reads values from an external referencing plant, a copy
of the original datapoint value of the input will be taken. Please note, that in this
case, the “Change of Value” (COV) value of the source point must be set to
appropriate (low) values in order to minimize falsification of the transmitted value.

Shows whether the hardware assigned to the datapoint is in proper condition or not.
Depending on the datapoint type, the following conditions may be displayed:
No Error Detected Loop is in proper condition, that is, present value is
reliable; that is, no other fault has been detected.
No Sensor Sensor may be not connected
No Output Hardware may be not connected
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.
NOTE: For binary output datapoints, the reliability will work only if the service type
of the corresponding NVo in CARE is set to ´acknowledged`.

Defines the value that will be written to the present value, if the priority list is empty
which means that no other value is present in the priority list. The relinquish default
value allows starting up a control system with a defined status/value.
The relinquish default value is predefined in the application in CARE and can be
changed in the Excel Web HTML Interface.
For further information on priority levels and command priorities, please refer to the
"Priority Level" section.
