Parameter Setting of the CP-2017/PCCX25
The following parameters define the synchronization between the redundant BSE pairs and
are valid both for BS E as well as AU redundancy.
Please note, that the following parameter setting must be performed
on both C-CPUs of the
two AUs
: (e.g. C4:CP-2017/PCCX25 of the one AU and the corresponding C4:CP-
2017/PCCX25 of the other AU)
•
In the OPM system technique, select the node
Redundancy
under C4:CP-2017/PCCX25
•
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:

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
200m, 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.
