Description
Channel
Click the channel number to configure parameters for the specified channel (0…7).
High Clamp Limit
Enter a High Clamp Limit (between -9999999…99999999). The default is 100.0000. The High Clamp
Limit must be greater than the Low Clamp Limit.
Any out of range value causes a profile validation error.
HI appears dimmed only when in Hard Run mode.
Unlatch High Clamp Limit
Click Unlatch High Clamp Limit to send a message to the module to unlatch a High Limit Alarm (online
only).
Unlatch (High Clamp) is enabled when online (including Hard Run mode) and when Latch Limit Alarms is
selected. Unlatch (High Clamp) is dimmed when offline and online (including Hard Run mode) when
Latch Limit Alarms is cleared.
Low Clamp Limit
Enter a Low Clamp Limit (between -9999999…99999999). The default is 0.0000. The Low Clamp Limit
must be less than the High Clamp Limit.
Any out of range value causes a profile validation error.
LO appears dimmed only when in Hard Run mode.
Unlatch Low Clamp Limit
Click Unlatch Low Clamp Limit to send a message to the module to unlatch a Low Limit Alarm (online

Ramp Alarm).
Ramp in Run Mode
Check this checkbox to establish whether the rate of change of the output is to be limited. If selected, then
changes due to command values, fault actions, and program actions are limited to the specified ramp
rate.
Ramp Rate
Enter the maximum ramp rate for changes in the output value (in seconds). The default is blank, which
results in an auditing error. This default forces you to enter an appropriate value.
Unlatch Ramp Rate
Click Unlatch Ramp Rate to send a message to the module to unlatch based on Ramp Rate.
Unlatch (Ramp Rate) is enabled when online (including Hard Run mode) and when Latch Rate Alarm is
selected. Unlatch (Low Clamp) is dimmed when offline and online (including Hard Run mode) when Latch
Rate Alarm is cleared.
