Follow the procedure below to perform program control for changing the Set
Point value in a ramp manner proportionately to the elapsed time.
Function blocks used:
Register the ramp program (max. seven steps, each step comprising a ramp
rate and soak value) in advance to the Step Ladder Program block. The Step
Ladder Program is used in combination with the run/stop command from the
Data
