K1: Mode group, channel, program operation, reset response
9.8 Block search Type 5 SERUPRO
DB21, ... DBX31.0-31.2 (REPOSPATHMODE)=1 corresponds to RMB
DB21, ... DBX31.0-31.2 (REPOSPATHMODE)=2 corresponds to RMI
DB21, ... DBX31.0-31.2 (REPOSPATHMODE)=3 corresponds to RME
DB21, ... DBX31.0-31.2 (REPOSPATHMODE)=4 corresponds to RMN
With DB21, ... DBX31.0-31.2 (REPOSPATHMODE0 to 2) = 0, no settings are overwritten and the current
program is valid. The interface signal responds to the level of the corresponding mode.
Note
RMN is a general REPOS extension and it is not restricted to SERUPRO. For SERUPRO RMI
and RMB are identical.
With DB21, ... DBX31.0–31.2 (REPOSPATHMODE0 to 2), the path as a whole is controlled.
The path axes cannot be changed individually.
The behavior of the other axis types can be changed individually using interface signal DB31,
... DBX10.0 (REPOSDELAY). This REPOS offset is not applied immediately, but only when it
is next programmed.

Read REPOS mode in synchronized actions
The valid REPOS mode of the interrupted block can be read via synchronized actions using system variable
$AC_REPOS_PATH_MODE=
0: not defined Repositioning not defined
1: RMB Repositioning to beginning
2: RMI Repositioning to point of interruption
3: RME Repositioning to block end point
4: RMN Repositioning to next geometric path point of interrupted block
