(main program)
The function is only available if there is an interruption point. After a program interruption
(CYCLE STOP, RESET or power off), the controller saves the coordinates of the
interruption point.
and subprogram)
The level can only be changed if it was previously possible to select an interruption point
in a subprogram. It is then possible to change the program level up to the main program
level and back to the level of the interruption point.
Note
You can search for a specific point in subprograms with the search pointer if there is no
interruption point.
Software option
You require the "Extended operator functions" option for the "Search pointer"
function (only for 828D).
