Program Coordination (Init, Start, Waitm, Waitmc, Waite, Setm, Clearm) - Siemens Sinumerik 840D sl Programming Manual

1.13 Program coordination (INIT, START, WAITM, WAITMC, WAITE, SETM,
CLEARM)
Function
Channels
A channel can process its own program independently of other channels. It can control the
axes and spindles temporarily assigned to it via the program.
Two or more channels can be set up for the control during startup.
Program coordination
If several channels are involved in the machining of a workpiece it may be necessary to
synchronize the programs.
There are special statements (commands) for this program coordination. Each statement is
programmed separately in a block.
Note
Program coordination is also possible in its own channels.
Program coordination statements
• Specification with absolute path
INIT (n,"/_HUGO_DIR/_N_name_MPF" )
or
INIT (n,"/_N_MPF_DIR/_N_name_MPF" )
Example:
INIT(2,"/_N_WKS_DIR/_DRESS_MPF")
G01F0.1
START
INIT (2,"/_N_WKS_DIR/
_N_UNDER_1_SPF")

1.13 Program coordination (INIT, START, WAITM, WAITMC, WAITE, SETM, CLEARM)

Flexible NC programming
The absolute path is programmed according to
the following rules:
- Current directory/_N_name_MPF
"current directory" stands for the selected
workpiece directory or the standard directory/
_N_MPF_DIR.
- Selects a particular program for execution in
a particular channel:
n: Number of the channel, the value depends
- on the control configuration
Complete program name
Up to SW 3:
At least one executable block must be
programmed between an init command (without
synchronization) and an NC start.
With subprogram calls "_SPF" must be added
to the path.
