FN18: SYS-DATUM READ Read system data
With the function FN 18: SYS-DATUM READ 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 number 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.
Value = 0: Server error has the normal effect.
Machine status, 20 1 - Active tool number
2 - Prepared tool number
3 - Active tool axis
0=X, 1=Y, 2=Z, 6=U, 7=V, 8=W
4 - Programmed spindle speed
5 - Active spindle status: –1=undefined, 0=M3 active,
1=M4 active, 2=M5 after M3, 3=M5 after M4
8 - Coolant status: 0=off, 1=on
9 - Active feed rate
10 - Index of prepared tool
11 - Index of active tool
Channel data, 25 1 - Channel number
Cycle parameter, 30 1 - Set-up clearance of active fixed cycle
2 - Drilling depth / milling depth of active fixed cycle
3 - Plunging depth of active fixed cycle
4 - Feed rate for pecking in active fixed cycle
