Description
EU of PV_SCALE The setting for the alarm limit used to detect the HI HI alarm condition.
None The priority of the HI HI alarm.
EU of PV_SCALE The setting for the alarm limit used to detect the HI alarm condition.
None The priority of the HI alarm.
None Allows the selection of input/output options used to alter the PV. Low
cutoff enabled is the only selectable option.
None Linearization type. Determines whether the field value is used directly
(Direct), is converted linearly (Indirect), or is converted with the square
root (Indirect Square Root).
None The LO alarm data, which includes a value of the alarm, a timestamp of
occurrence and the state of the alarm.
EU of PV_SCALE The setting for the alarm limit used to detect the LO alarm condition.
None The LO LO alarm data, which includes a value of the alarm, a timestamp
of occurrence and the state of the alarm.
EU of PV_SCALE The setting for the alarm limit used to detect the LO LO alarm condi-
tion.
None The priority of the LO LO alarm.
None The priority of the LO alarm.
% If percentage value of transducer input fails below this, PV = 0.
None The actual, target, permitted, and normal modes of the block.
Target: The mode to "go to"
Actual: The mode the "block is currently in"
Permitted: Allowed modes that target may take on
Normal: Most common mode for target
EU of OUT_SCALE The block output value and status.
None Discrete output to indicate a selected alarm condition.
None The high and low scale values, engineering units code, and number of
digits to the right of the decimal point associated with OUT.
EU of XD_SCALE The process variable used in block execution.
Seconds The time constant of the first-order PV filter. It is the time required for a
63% change in the IN value.
None A group of data that contains the current transducer value and status,
the simulated transducer value and status, and the enable/disable bit.
None The strategy field can be used to identify grouping of blocks. This data
is not checked or processed by the block.
None The revision level of the static data associated with the function block.
The revision value will be incremented each time a static parameter val-
ue in the block is changed.
None The user description of the intended application of the block.
None This alert is generated by any change to the static data.
% of OUT Range The average absolute error between the PV and its previous mean value
over that evaluation time defined by VAR_SCAN.
Seconds The time over which the VAR_INDEX is evaluated.
None The high and low scale values, engineering units code, and number of
digits to the right of the decimal point associated with the channel in-
put value.
The XD_SCALE units code must match the units code of the measure-
ment channel in the transducer block. If the units do not match, the
block will not transition to MAN or AUTO.
