In the OPM system technique select
Red_sync mode
under the
Redundancy
node below
the M-CPU:
•
In the
Value
column for the parameters
Red_sync mode
and
Red_sync org_img
select
one of the following entries from the dropdown list:
Please note, that some parameters are available for all types of redundancy control (global
redundancy switchover with SCA-RS, global redundancy switchover with application-related
voting, line-by-line redundancy switchover with SCA-RS, line-by-line redundancy switchover
with application-related voting), unless explicitly specified otherwise in the column “Comment”.

Red_sync mode
No synchronization:
if no CAEx
plus
is used on
this BSE and also no singular Ax-PE is
coupled
High Speed Link (HSL)
: if CAEx
plus
is used
on both redundancy BSEs
HSL with singular Ax-PEs
: if a singular Ax-PE
is coupled on this BSE. The CAEx
plus
application is also synchronized over the HSL
Sync. via communication
:
If the distance between both AUs is more than
200 m, the redundancy synchronization must
also be performed over a separate fast data
connection. In this case no singular Ax-PEs
are allowed.
Specific settings for
redundant AUs, not
relevant with CPU
redundancy
Red_sync org_img
One element of the redundancy pair must be
defined as
Original
, the other as
Image
.
This parameter defines, whether this BSE is to
be the Original or the Image element of the
redundancy pair.
The second element of the redundancy pair
must be defined at
Address of the redundant
BSE
(see below)
The mirroring of the
parameter is otherwise not
possible.
