12.22.23 Flow Control
By default this command (category Online) is available in the Debug menu. It serves to
switch on and off the Flow Control (Powerflow) function, which is supported for the
language editors ST, FUP, LD and IL.
Activated Flow Control allows to track the execution of the application program.
1. The current values of the variables, thus also results of function calls and
operations, will be displayed within the editor views, each at the exact position and
time of execution. For comparison: The standard monitoring functionality just
provides the value a variable has between two execution cycles.
2. Exactly those code lines resp. networks which are processed in the current cycle will
be displayed color-coded.
Flow Control can only be activated in online mode and works exactly for the visible
part of the currently active editor view. 'Flow Active' is displayed in the status bar only
as long as the feature is activated and an editor view showing any flow positions
(processed parts of the code) is opened.
Note: Activated Flow Control increases the run time of the application! If option
Secure online mode is activated in the communication settings dialog, then a
message box will appear, always when the user is going to activate Flow Control.
One will be asked whether the function should really be switched on and one has
the possibility to abort the activation.
