9 Commands for Controlling Processes and
Programs
9.1 Process Control Commands
The multiple-process structure of the CNC makes it necessary to coordi-
nate the individual processes used in the CNC. If more than two proc-
esses are present on the CNC, the process whose number is "0" is gen-
erally used for program coordination. The number "0" process thus han-
dles the management function used to coordinate all processes which are
involved in the work. The process control commands are passed to the
CNC
↔
SPS interface.

In addition to the management process, the CNC can control six additio-
nal processes and up to 25 external mechanisms.
