Creating Blocks and Integrating Them Into The User Program
Integrate the following FC 101 block in your user program (in OB 1, for example). This block
requires the DB1 data block with a length of 16 bytes. In the example below, the start is
initiated by setting memory bit 30.0 (in the plus direction) or 30.1 (in the minus direction) with
the programming device. You select rapid or creep feed using memory bit 30.2.
