EXTERN_FUNCTION_MASK
Functions in the ISO mode are affected by this machine data.
Bit 0=0: ISO Mode T: A" and "C" are interpreted as axes. If contour definition is
programmed, there must be a comma before "A" or "C".
Bit 0=1: "A" and "C" in the part program are always interpreted as contour definition.
No Axis A or Axis C should exist.
Bit 1=0: ISO mode T G10 P<100 tool geometry
P>100 tool wear
Bit 1=1: G10 P<10 000 tool geometry
P>10 000 tool wear
Bit 2=0: Dwell time G04: Always [s] or [ms]
Bit 2=1: If G95 is active, dwell time is in spindle revolutions
Bit 3=0: Errors in the ISO scanner lead to alarm
Example: N5 G291 ; ISO dialect mode
N10 WAIT ; Alarm 12080 "WAIT unknown"
N15 G91 G500 ; Alarm 12080 "G500 unknown"
Bit 3=1: Errors in the ISO scanner are not output, the block is forwarded to the Siemens
translator
Example: N5 G291 ; ISO dialect mode
N10 WAIT ; Block is processed by Siemens translator
N15 G91 G500 ; Block is processed by Siemens translator
N20 X Y ; block is processed by ISO translator due to G291, G91 from N15 is active
Bit 4=0: G00 is traversed to the active exact stop function.
Example: In G64, even G00 blocks are traversed with G64
Bit 4=1: G00 blocks are always traversed with G09, even if G64 is active
Bit 5=0: Movements of the rotary axis are executed along the shortest path
Bit 5=1: Movements of the rotary axis are executed in the positive or negative direction of
rotation, depending on the sign
Bit 6=0: only four-digit program number is allowed
Bit 6=1: eight digit program number is allowed. If there are less than 4 digits, the figure is
increased by 4 digits.
Bit 7=0: Axis programming in geo axis interchange/parallel axes is compatible with the ISO
mode
Bit 7=1: Axis programming in geo axis interchange/parallel axes is compatible with the
Siemens mode, in the ISO mode
Bit 8=0: For cycles, the F value is always transferred as feedrate
Bit 8=1: For threading cycles, the F value is always interpreted as lead
Bit 9=0: In the ISO mode T for G84, G88 and in the standard mode F for G95, it is multiplied
with 0.01 mm or 0.0001 inch
Bit 9=1: In the ISO mode T for G84, G88 and in the standard mode F for G95, it is multiplied
with 0.01 mm or 0.0001 inch
Bit 10=0: In M96 Pxx, during interrupt, the program with Pxx progr. is always called.
Bit 10=1: In M96 Pxx, CUCLE396.spf is always called in case of interrupt.
Bit 11=0: G54.1 is displayed during the programming of G54 Pxx.
Bit 11=1: G54Px is always displayed while programming G54 Pxx or G54.1 Px.
Bit 12=0: $P_ISO_STACK is not changed on calling the subroutine defined with M96 Pxx.
Bit 12=1: $P_ISO_STACK is incremented on calling the subroutine defined with M96 Pxx.
