Description
0%
The value that represents 0% of the engineering units. The default is 0.00.
Bias and scaling
Enable
additional PV
bias and
scaling
Used to calibrate engineering units, the bias value is added to the PV raw value
after the data format is applied and before the PV algorithm is executed.
When selected, performs the following calculation to determine the PV value:
PV = PV Field Value * Scale + Bias
Services
Scanning and
control
enabled
Enable and disables scanning and control of the point. You typically need to
disable a point if the associated device is being serviced or repaired—this
prevents misleading alarms being generated.
In addition to using this check box, you can also click
(Enable/Disable) on the
toolbar, or press F11 (or LOAD on an OEP/IKB keyboard).
Alarms
enabled
Enables and disables all alarms for the point.
This check box overrides each of the
Enable Alarm
check boxes for each state,
which are located on the
Alarms
tab.
Journal only
option
When selected, handles all alarms for the point as journaled events. Note that
Alarms enabled
must be selected for this option to work.
Manual PV
When selected, the operator is permitted to change the PV.
Field value
The current value of the point in the field. Operators can use this to verify the
value before disabling the
Manual PV
option.
Displays
Associated
display
Lists the display, if any, associated with this point.
Algorithms
PV algorithm
Lists the PV algorithm number, if specified, attached to this point. Double-click
the number to display algorithm details.
Action
algorithm
Lists the action algorithm number, if specified, attached to this point. Double-
click the number to display algorithm details.
