The Enhanced Ramp function block is used to ramp a function block parameter to a target value at a specific rate or over a specified amount of time. For example, the Enhanced Ramp function block can be used to allow an operator to set up a PID setpoint ramp over a desired amount of time to gradually increase flow to a vessel. The Enhanced Ramp function block is associated with a target function block by specifying external references, and can be used to ramp parameters in either or both directions.
The following diagram shows an example of output from the Enhanced Ramp function block:
