2.5.3 Cascaded block search
Functionality
The "Cascaded block search" function can be used to start another block search from the
status "Search target found". The cascading can be continued after each located search
target as often as you want and is applicable to the following block search functions:
• Type 1 block search without calculation
• Type 2 block search with calculation at contour
• Type 3 block search with calculation at block end point
Note
Another "Cascaded block search" can be started from the stopped program execution
only if the search target has been found.
Activation
The "Cascaded block search" is configured in existing machine data:
MD11450 $MN_SEARCH_RUN_MODE.
• Cascaded block search is enabled (i.e., several search targets can be specified)
with Bit 3 = 0 (FALSE).
• For compatibility reasons, the cascaded block search can be disabled with Bit 3 = 1
(TRUE). By default, the cascaded block search is set with Bit 3 = 0.
Execution behavior
Search target found, restart search
When the search target is reached, the program execution stops and the search target is
displayed as a current block. After each located search target, a new block search can be
repeated as often as you want.
Change search target specifications
You can change the search target specifications and block search function prior to each
block search start.
