Figure 58: Change Values
This is done with option 'Online' 'Write Values' (Figure 59) or alternatively with
the key combination <Ctrl.> + <F7>. The values of the variables A and B are
now TRUE (= ON). This causes variable C to change from FALSE to TRUE (the
colour in the bottom part of the window changes to blue) as a result of the And
link (
Figure 60).
The colour changes may be difficult to see on the (monochrome) printout of this
manual. This shows that going through this manual does not replace the
practical work with the controller. It is only meant to support you. You will get
most benefit by putting the example in practice and trying own ideas.
Figure 59: Write Values
You can test other combinations of A and B in the same way, e.g. Figure 60.
