How the Ramp button works at runtime
When the operator presses the
Ramp
button, the application reads the Value connection value, stores a local copy of the value, adds or subtracts the ramp amount from the local value, and writes the result to the Value connection at the data source.The
Ramp
button’s behavior at runtime also depends on whether you set up auto repeat.
TIP:
Pressing a
Ramp
button a second time before the previous increment or decrement has finished updating can affect the accuracy of the resulting numeric value. Wait for each increment or decrement to finish updating before pressing the Ramp
button again.Open and close graphic displays
- When you open a display at runtime, the application reads the Value connection value.
- When you close a display at runtime, if the button is in auto repeat mode, the button is released and the value of the button at the moment it is released is written to the Value connection.
