Instructions In Msplit.sys - HEIDENHAIN TNC 426 PB/M Technical Manual

Instructions in
MSPLIT.SYS
6 – 298
REMAIN=OUTPUT
All M functions that are not defined in MGROUPS.SYS are transferred during
the block scan to the PLC. If you do not enter this instruction such M functions
are ignored.
Note
In the following functions you must use REMAIN=OUTPUT:
n
Datum shift with M4132
n
PLC positioning except with TOOL CALL
n
Traverse range switchover with M4135, if MP7490=1
n
Switchover spindle 1/spindle 2 with Module 9175
If the PLC shifts the datum or switches the traverse range, the error message
PLC function not permitted appears.
ORDER=PRIO
The M functions are transferred in the sequence in which they are entered in
the MGROUPS.SYS file. If you do not enter this instruction, the M functions
are transferred after a block scan in the sequence in which they were
programmed.
HEIDENHAIN recommends that you avoid using this instruction.
TOOLGROUP, TDEFGROUP, SPINDLEGROUP, FN19GROUP
In conjunction with ORDER=PRIO, the output sequence of the S/T/Q strobes
after a block scan is specified in the MGROUPS.SYS file. HEIDENHAIN
recommends that you avoid using these instructions.
NCMACRO=TC, M
With an M function or during a TOOL CALL, you can also call an NC program
instead of a T strobe ((See "Tool Changer" on page 6 – 400) and (See "Calling
an NC macro with an M function" on page 6 – 287)).
The instruction NCMACRO= prevents NC macros for tool change (TC) or NC
macros for M functions (M) from running during the block scan. Rather they
are started at the end of the block scan.
M functions that are effective in several groups are divided in the MSPLIT.SYS
file into function components.
Example: M13=M3, M8
