Activate function 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.
