Chapter 2 Program a sequential function chart

Enter a BOOL expression

The simplest way to program the transition is to enter the conditions as a BOOL

expression in structured text.

1. Double-click the text area of the transition.

2. Type the BOOL expression that determines when the transition is TRUE

or FALSE.

3. To close the text entry window, press Ctrl+Enter.

This example shows three transitions that use a BOOL expression (see
