ItpIsFeedFromBackupList
The function ItpIsFeedFromBackupList becomes TRUE when the feed entries (SAF & SVB) were sent from the backup list. During backward movement all entries are sent from the backup list. If the program is executed in forward mode, the first entries usually also originate from the backup list. This is dependent of the number of retraced entries and the number of entries in the SVB and SAF tables at the time at which tracing was called. All further commands originate from the ‚original’ code.
While the NCI is processing the backup list, not all functions are available or meaningful. Here are a few examples:
- Decoder stops such as @714 are not evaluated
- Modifications of R-parameters do not take effect as long as the motion takes place on the backup path (forward or backward). R-parameters modifications take effect again as soon as the path data no longer come from the backup list.
