HP Output Dest
Choose a digital output to toggle when the high process alarm
occurs. This may be any available hardware output or Soft
Boolean register accessible by the logic program. The default
for this parameter is
Not Assigned . Outputs that are already
assigned to control output destinations will be rejected. The
same output may not be used for multiple alarm output
destinations.
Range: Not Assigned, or any of the digital outputs on the DigI/O
spreadsheet, or any of the Soft Bool registers.
HD Offset
Designate an offset value that determines the high deviation
alarm limit relative to the current set point. The high deviation
alarm occurs when the process variable is greater than the
channel set point plus this value. The alarm limit changes
when the set point changes. The default high deviation alarm
offset is
0 .
Range: same as the range of the input type selected. See Table
3.15 on page 130 .
HD Type
Set the high deviation alarm function. See Process Alarms on
page 95 for a description of the settings.
Range: Alarm or Control
HD Enable
Set this field to enable or disable the high deviation alarm.
When it is Enabled, the high deviation alarm activates if the
process variable (PV) rises above the set point by more than the
HD Offset . The PV must drop below the high deviation limit
minus the alarm deadband to be reset (cleared). When this
parameter is set to
Disabled , the high deviation alarm does not
occur.
Range: Enable or Disable
HD Output Dest
Choose a digital output to toggle when the high deviation alarm
occurs. This may be any available hardware output or Soft
Boolean register accessible by the logic program. The default
for this parameter is
Not Assigned . Outputs that are already
assigned to control output destinations will be rejected. The
same output may not be used for multiple alarm output
destinations.
Range: Not Assigned, or any of the digital outputs on the DigI/O
spreadsheet, or any of the Soft Bool registers.
