The following commands, corresponding to those in the Online menu, are available
via buttons:
• Force Values: All entries in the current writelist are transferred to the forcelist, that
is the values of the variables in the controller are forced. All variables marked with
'Release Force' are no longer forced. The dialog is then closed.
• Write Values: All entries in the current writelist are written once only to the
corresponding variables in the controller. The dialog is then closed.
• Release Force: All entries in the forcelist will be deleted or, if a writelist is present,
the dialog "Delete write-/forcelist" comes up, in which the user must decide
whether he only wants to release forcing or discard the writelist, or both. The
dialog will close at that point, or after the selection dialog is closed as the case may
be.
6.6.19 'Online' 'Show Call Stack'
You can run this command when the Simulation Mode stops at a breakpoint. You will
be given a dialog box with a list of the POU Call Stack.
Example of a Call Stack
The first POU is always PLC_PRG, because this is where the executing begins.
The last POU is always the POU being executed.
After you have selected a POU and have pressed the Go to button, the selected POU is
loaded in its editor, and it will display the line or network being processed.
