Limits view parameters
The
Limits
view include these parameters:Parameter | Description |
|---|---|
High Clamp | Indicates the maximum value the output can take within the process with a range
from -1.0E11...+1.0E11. The default value is 100% for Current mode. The value must
be greater than the Low Clamp value. If an output above the high limit is
requested, the HLimit alarm is set and the output signal remains at the configured
high limit. |
Low Clamp | Indicates the minimum value the output can take within the process with a range
from -1.0E11...+1.0E11. The default value is 0. The value must be less than the
High Clamp value. If an output below the low limit is requested, the LLimit alarm
is set and the output signal remains at the configured low limit. |
Disable All Alarms | Disables all alarms when the alarms will not be used. |
Latch Clamp Alarms | Allows the latch clamp alarm to remain latched. This can be useful if alarm
conditions need to be acknowledged by an operator. |
Ramp in Run Mode | Enables output ramping during Run Mode. Output changes will be limited to the
maximum ramp rate during Run Mode. |
Latch Rate Alarm | Allows the latch Rate Alarm to remain latched. This can be useful if alarm
conditions need to be acknowledged by an operator. |
Ramp to Program Mode | Enables output ramping when transitioning to Program Mode or Inhibit mode. Output
changes will be limited to the maximum ramp rate when transitioning to the program
value. |
Ramp to Fault Mode and Final Fault State | Enables output ramping when transitioning to either fault mode or final fault
state. Output changes are limited to the maximum ramp rate when transitioning to
the fault value or to the fault final state. |
Ramp Rate | Defines the maximum rate at which the output is allowed to transition in
Engineering Units/sec. This should be a non-negative value. |
