REPOS operations with VDI signals
Control REPOS with VDI interface signals
REPOS offsets can be positively influenced with the following channelspecific VDI interface
signals from the PLC:
DB21, ... DBX31.0-31.2 (REPOSPATHMODE0 to 2) channel-specific*
DB21, ... DBX31.4 (REPOSMODEEDGE) channel-specific
DB31, ... DBX10.0 (REPOSDELAY) axis/spindle*
(This axial interface does not affect machine axes that form a path.)
DB31, ... DBX72.0 (REPOSDELAY) axis/spindle
* These signals are available in the respective DB of the HMI or PLC.
REPOS acknowledgement signals
The following VDI signals can be used to acknowledge from the NCK functions that control
the REPOS response via PLC:
DB21, ... DBX319.0 (REPOSMODEEDGEACKN) channel-specific
DB21, ... DBX319.1-319.3 (Repos Path Mode Ackn0-2) channel-specific
DB21, ... DBX319.5 (Repos DEFERRAL Chan) channel-specific
DB31, ... DBX70.0 (Repos offset) axis/spindle
DB31, ... DBX70.1 (Repos offset valid) axis/spindle
DB31, ... DBX70.2 (Repos Delay Ackn) axis/spindle
DB31, ... DBX76.4 (path axis) axis/spindle
For further information, see "REPOS offset in the interface"
REPOS acknowledgement operations
A handshake is made using the channel-specific VDI signal:
DB21, ... DBX319.0 (REPOSMODEEDGEACKN)
in which interface signal:
DB21, ... DBX31.4 (REPOSMODEEDGE)
is detected by the NC and is acknowledged to the PLC with DB21, ... DBX319.0.
Note
If the NCK has not yet acknowledged interface signal:
DB21, ... DBX31.4 (REPOSMODEEDGE)
with interface signal:
DB21, ... DBX319.0 (REPOSMODEEDGEACKN)
a RESET in this situation causes the program to abort, and the REPOS that is to be used to
control the REPOSPATHMODE can no longer take place.
