PI service: FINDBL
Function: Activate block search
A channel is switched to block search mode and the appropriate acknowledgment then transmitted. The block
search is then executed immediately by the NCK. The search pointer must already be in the NCK at this point in
time. The search can be interrupted at any time by an NC RESET. Once the search is successfully completed,
the normal processing mode is reactivated automatically. NC Start then takes effect from the located search
target. The operator is responsible for providing a collision­free approach path.
