FN 18: SYS-DATUM READ: Reading system data
With the
FN 18: SYS-DATUM READ function you can read system
data and store them in Q parameters. You select the system data
through a group name (ID number), and additionally through a
number and an index.
Group name, ID no. Number Index Meaning
Program information, 10 3 - Number of the active fixed cycle
103 Q parameter
number Relevant within NC cycles; for inquiry as to
whether the Q parameter given under IDX
was explicitly stated in the associated CYCLE
DEF.
System jump addresses, 13 1 - Label jumped to during M2/M30 instead of
ending the current program. Value = 0: M2/
M30 has the normal effect
2 - Label jumped to if FN14: ERROR after the
NC CANCEL reaction instead of aborting
the program with an error. The error number
programmed in the FN14 command can be
read under ID992 NR14. Value = 0: FN14 has
the normal effect.
3 - Label jumped to in the event of an internal
server error (SQL, PLC, CFG) instead of
aborting the program with an error message.
Value = 0: Server error has the normal effect.

0=X, 1=Y, 2=Z, 6=U, 7=V, 8=W
4 - Programmed spindle speed
5 - Active spindle condition: -1=not defined,
0=M3 active,
1=M4 active, 2=M5 after M3, 3=M5 after M4
7 - Gear range
8 - Coolant status: 0=off, 1=on
9 - Active feed rate
10 - Index of prepared tool
11 - Index of active tool
