Add a Function to a Ladder Diagram

Functions are single calculations that can be applied to a value. Each function reads an input, performs a calculation, and outputs the result of the calculation as a value. There are many types of function (each function type performs a different type of calculation).

Functions are useful for converting values, adding values, etc.

To add a function to a Ladder Diagram:

1. Right-click on the background of the Ladder Diagram.
   A context sensitive menu is displayed.
2. Select the Functions option to display another menu.
3. Select the option for the type of function that you want to add to the Ladder Diagram.
   A further menu is displayed.

   

4. Select the function that you require.
   The function is added to the Ladder Diagram.
