Parameter Setting Of The Cp-2017/Pccx25 - Siemens SICAM AK Manual

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:

Description/Value
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.
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)
