6.9.2 Frames active in the channel
Function
$P_NCBFRAME[n]
Current NCU-global base frames
The current global base frame array elements can be
written and read via system variable
$P_NCBFRAME[n]. The resulting total base frame is
calculated by means of the write process in the
channel.
The modified frame is only active in the channel in
which the frame was programmed. If the frame is to
be changed for all channels of an NCU, both [n] and
$P_NCBFRAME[n] have to be programmed. The
other channels must then still activate the frame
with, for example, G54. When writing a base frame,
the total base frame is calculated again.
$P_CHBFRAME[n]
Current channel base frames
The current channel base frame array elements can
be written and read via system variable
$P_CHBFRAME[n]. The resulting total base frame is
calculated by means of the write process in the
channel. When writing a base frame, the total base
frame is calculated again.
$P_BFRAME
Current 1st base frame in the channel
The current base frame can be written and read in
the part program via the predefined frame variable
$P_BFRAME with the array index 0 that is valid in
the part program. The written base frame is
immediately included in the calculation.
$P_BFRAME is identical to $P_CHBFRAME[0]. By
default, the system variable always a valid value. If
there is no channel-specific base frame, an alarm is
issued at read/write: "Frame: instruction not
permissible".
