The conditional function works the following way:
The program always calculates the condition entered in the IF window and checks if the
condition is TRUE or FALSE.
If the condition entered in the IF window is TRUE, the program calculates the condition
entered in the THEN window. The returned value is the content of the new variable
(entered in ‘Name’).
If the condition entered in the IF window is FALSE, the program calculates the condition
entered in the OTHERWISE window. The returned value is the content of the new variable
(entered in ‘Name’).
The reset value is always set for the new variable (entered in ‘Name’):
– before If-condition becomes TRUE for the first time after power-up
– when If-condition changes state from FALSE to TRUE.
An example of a condition to set up the maximum front brake pressure is given on the
next page.
The conditional function is displayed in the DDU 9 math channel window.
