Global frames can be written and read from all
channels of an NCU. When writing global frames,
the user must pay attention to channel coordination,
for example, by using Wait marks (WAITMC).
NCU-global settable frames: $P_UIFR[n]
The configuration of all settable frames G500, G54...G599
can be either NCU-global or channel-specific.
Machine manufacturer
All settable frames can be reconfigured as global
frames via MD 18601
MM_NUM_GLOBAL_USER_FRAMES.
See /FB/ K2, Axes, Coordinate Systems, Frames.
Channel axis identifiers and machine axis identifiers
can be used as axis identifiers for the frame program
commands. Programming of geometry identifiers is
rejected with an alarm.

6.9.1 Channel-specific frames

Function
The number of base frames can be configured in the
channel via MD28081 MM_NUM_BASE_FRAMES.
The standard configuration provides at least one base
frame per channel. A maximum of 8 base frames are
supported per channel. In addition to the 8 base
frames, there can also be 8 NCU-global base frames
in the channel.
Settable frames/base frames can be written and read
from
• the PLC
• via the part program and
via the OPI.
Fine offset is also possible for global frames.
Suppression of global frames also takes place, as is
the case with channel-specific frames, via G53, G153,
SUPA and G500.
