Default value: 0
Active: In the block prior to decoding
Bit 4 Bit 4=1 FIFO active (see Section entitled "Functional Descriptions")
Bit 3 Bit 3=0 Programming function G176 cannot be used.
Bit 3=1 Programming function G176 is used to 'freeze' the zero offsets for the
angles of rotation and the tool length compensations, i.e. these values
are not updated in every block. This reduces the amount of time
required for block changes. G176 can be revoked with G175 (initial
setting).
Bit 2 Bit 2=1 The "Axis converter/Spindle converter" function is active (see Section
entitled "Functional Descriptions").
Bit 1 Bit 1=1 Function BLOCK SKIP LEVELS is active (refer also to
SINUMERIK 840C Programming Guide).
Active:
Bit 0 Bit 0=1 Program coordination permits the user to program coordination
commands in plaintext in the part program. The coordination commands
are transferred to the NC PLC interface. The PLC performs the
coordination itself (see also SINUMERIK 840C Programming Guide).
Active:

Bit 0 MCD (Multi-channel display)
Several channels can be displayed at any one time on the screen for
operator support when multiple machine tools are used. The operator
can then check the allocation of programs that run simultaneously and
test the synchronization marks in test mode.
