# Procedure with enabled "PLC code handles block search"

If the key "PLC code handles block search" appears in the visualisation, the user need not carry out any further interaction in the visualisation except for parameterising the block search type and then starting the NC program.

The required handshakes and starts are acknowledged and commanded by the automatic state indicator at the end of the POU BlockSearch.

## Notice

As you can see from the automatic state indicator, Start 2 and Start 3 can also be commanded by the control unit gpCh[..]^.bahn_mc_control.continue_motion (CNC Build > 2800).
