10.5 Frames
$P_UIFRNUM (number of active settable frame)
System variable $P_UIFRNUM can be used to read the index <n> of the settable frame of the
data management active in the channel:
Settable frame active in the channel $P_IFRAME == $P_UIFR[ $P_UIFRNUM ]
Programming
A channel-specific settable frame of the data management $P_UIFR[<n>] becomes the
settable frame $P_IFRAME active in the channel through the appropriate command (G54 ...
G57, G505 ... G599 and G500).
Supplementary conditions
Writing of settable frames through HMI/PLC
Only the settable frames of the data management can be written from the HMI or the PLC user
program.
10.5.5.3 Grinding frames $P_GFR[<n>]
Grinding frames are additional work offsets or "fit-dependent corrections" available particularly
for the grinding technology. They have an additive effect on the work offsets of the settable
frames (Page 729).
