Latch Limit Alarms Check the box to latch an alarm if the
controller data value exceeds the
clamping limit.
See page 170 in Chapter 8 for details.
Latch Rate Alarm Check the box to latch an alarm if the
output single changes at a rate that
exceeds the ramping limit.
See page 169 in Chapter 8 for details.
IMPORTANT
Clamping is only available in floating point mode.
Clamp values are in engineering scaling units and are not
automatically updated when the engineering high and low
scaling units are changed. Failure to update the clamp
values may generate a very small output signal that could
be misinterpreted as a hardware problem.
