Detailed description
2.5 Block search
Basic logic functions: Mode group, channel, program operation, reset response (K1)
44 Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Example ASUB activation
Sequence for the automatic start of an ASUB after block search:
1. Start block search (with/without calculation, at contour, at endofblock point).
2. Stop after "Search target found".
3. NC Start for output of action blocks.
4. Last action block is activated.
5. Automatic start of /_N_CMA_DIR/_N_PROG_EVENT_SPF as an ASUB.
6. The NC will stop after changing the last ASUB block (REPOSA command) and output the
alarm 10208 depending on machine data:
MD11450 $MN_SEARCH_RUN_MODE with Bit 0.
2.5.4 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 the 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.
