Acceptance timing of REPOS VDI signals
With the 0/1 edge of the channel-specific VDI signal (PLC→NCK):
DB21, ... DBX31.4 (REPOSMODEEDGE)
the level signals of:
DB21, ... DBX31.0-31.2 (REPOSPATHMODE0 to 2)
and
DB31, ... DBX10.0 (REPOSDELAY)
are transferred to the NC.
The levels relate to the current block in the main run. There are two different cases:
Case A:
One repositioning block of a currently active REPOS operation is contained in the main run.
The active REPOS operation is aborted, restarted and the REPOS offsets controlled via the
signals:
DB21, ... DBX31.0-31.2 (REPOSPATHMODE0 to 2)
and
DB31, ... DBX10.0 (REPOSDELAY)
.
Case B:
No repositioning block of a currently active REPOS operation is contained in the main run.
Each future REPOS operation wishing to reapproach the current main program block is
controlled by the level of interface signal:
DB21, ... DBX31.0-31.2 (REPOSPATHMODE0 to 2)
and
DB31, ... DBX10.0 (REPOSDELAY)
.
