Main program (CC_RESU.MPF)

Function
In addition to the calls for the RESU-specific subprograms, the RESU main program
"CC_RESU.MPF" contains the traversing blocks generated from the traversing blocks logged
in the block buffer for reverse/forward travel along the contour. The program is always
regenerated by the RESU function if, once the part program has been interrupted, the status
of the following interface signal changes:
DB21, ... DBX0.1 (Reverse / Forward)
Note
CC_RESU.MPF must not be changed. User-specific adjustments are to be made in the
corresponding RESU-specific subprograms.
Error messages
By default, RESU generates traversing blocks for the entire retraceable contour range logged
in the block buffer. If there is not enough memory for all traversing blocks to be generated in
the parameterized memory area of the RESU main program (see Section "RESU main program
memory area (Page 708)"), RESU reduces the number of generated traversing blocks.
The lacking memory and/or reduction in the number of the generated traversing blocks is
indicated by an alarm:
