D18: Read system data
With the D18 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.
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
7 - Gear range
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
