4.7.5 Entering the search target via search pointer
Enter the program point which you would like to proceed to in the "Search Pointer" window.
Software option
You require the "Extended operator functions" option for the "Search pointer"
function (only for 828D).
Precondition
The program is selected and the controller is in Reset mode.
Screen form
Each line represents one program level. The actual number of levels in the program depends
on the nesting depth of the program.
Level 1 always corresponds to the main program and all other levels correspond to
subprograms.
You must enter the target in the line of the window corresponding to the program level in
which the target is located.
For example, if the target is located in the subprogram called directly from the main program,
you must enter the target in program level 2.
The specified target must always be unambiguous. This means, for example, that if the
subprogram is called in the main program in two different places, you must also specify a
target in program level 1 (main program).
Procedure
1. Press the "Block search" softkey.
2. Press the "Search pointer" softkey.
3. Enter the full path of the program as well as the subprograms, if
required, in the input fields.
4. Press the "Start search" softkey.
The search starts. Your specified search mode will be taken into
account.
The Search window closes. The current block will be displayed in the
"Program" window as soon as the target is found.
5. Press the <CYCLE START> key twice.
Processing is continued from the defined location.
