DBX318.1
Block search via program test is active
Edge evaluation: no
Signal state 1 or During the processing of the part program block in context of block search (internal channel status:
edge change "Program test"), up to the change of the target block in the main execution (Program status:
0 → 1 "Stopped").
Signal status 0 or With the change of the target block in the main execution (internal channel status: "Program test" is
edge change de-selected; Stop condition: "Search target found" is displayed).
1 → 0
Special cases, The block search (SERUPRO) can only be activated in AUTOMATIC mode in program status
errors, ...... "Aborted".

DBX319.0 REPOSMODEEDGEACKN
Edge evaluation: yes
Signal state 1 or The interface signal detected by the NCK:
edge change DB21, ... DBX31.4 (REPOSMODEEDGE)
0 → 1 is acknowledged with 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 taken over in the NC.
The levels relate to the current block in the main run.
Signal state 0 or SERUPRO-ASUP stopped automatically before the REPOS and NST DB21, ... DBX319
edge change (REPOSMODEEDGE) does not affect SERUPRO approach.
1 → 0
Corresponds to .... DB21, ... DBX31.4 (REPOSMODEEDGE)

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.
