PPID ramp and operator ramp values

On the instruction in the routine, perform one of these actions:

On the Ladder or FBD instruction, select .
In the Structured Text editor, right-click the tag name and select
Configure <tag name>
.

Under the

General

tab, select the

SP ramp

tab.

In the Operator

Target

box, enter the setpoint ramp target value in PV engineering units. The setpoint target value is clamped at the SP High/Low limit, and the constrained value actually used appears in this box when ramping starts. If the setting requires a signature, this will enforce security from the HMI and disable the setting from the Logix Designer dialog.

In the Operator

Time

box, enter the setpoint ramp time in seconds. The setpoint ramp time is recalculated when the requested rate-of-change exceeds the rate-of-change increasing or decreasing limits. The new time to reach target appears when ramping starts. If the setting requires a signature, this will enforce security from the HMI and disable the setting from the Logix Designer dialog.

Select the

Ramping Start

and

Stop

buttons to start and stop the setpoint ramping function. The

Start

button is enabled when the ramping wizard is enabled and ready to use in Operator mode. After startup, the setpoint ramps until it reaches the target. Select

Stop

to terminate ramping before the setpoint reaches the target. The action is immediate if the command request does not need to be confirmed by the operator. If the command request requires a signature, this will enforce security from the HMI and disable the command from the Logix Designer dialog.
