DBX319.0 REPOSMODEEDGEACKN
Edge evaluation: yes
Signal state 1 or The interface signal identified by the NCK:
edge change DB21, ... DBX31.4 (REPOSMODEEDGE)
0 → 1 is acknowledged using the interface signal:
DB21, ... DBX319.0 (REPOSMODEEDGEACKN),
if level signals from:
DB21, ... DBX31.0 - DBX31.2 (REPOSMODE0-2)
and from:
DB31, ... DBX10.0 (REPOSDELAY)
are transferred to the NC.
The levels relate to the current block in the main run.
Signal state 0 or SERUPRO-ASUB stops automatically before REPOS, and IS "REPOSMODEEDGE" does not
edge change influence the SERUPRO approach.
1 → 0
Corresponds to .... DB21, ... DBX31.4 (REPOSMODEEDGE)
DB21, ...
DBX319.1 - Repos Path Mode Ackn 0 - 2
DBX319.3
Edge evaluation: no
Signal state 1 Using the interface signal:
DB21, ... DBX319.1 - DBX319.3 (Repos Path Mode Ackn 0-2)
with the 3 bits, one of the functions for the re-approach point RMB, RMI, RME or RMN can be
acknowledged according to the following coding to the PLC:
DB21, ... DBX319.1 - DBX319.3 = 1 → RMB: Re-approach at the start of the block
DB21, ... DBX319.1 - DBX319.3 = 2 → RMI: Re-approach at the point of interruption
DB21, ... DBX319.1 - DBX319.3 = 3 → RME: Re-approach at the end of the block
DB21, ... DBX319.1 - DBX319.3 = 4 → RMN: Re-approach at the nearest path point
Signal state 0 DB21, ... DBX319.1 - DBX319.3 = 0
→ RMNOTDEF: The ReposMode that is not re-defined is acknowledged to the PLC.
