9.1.12 Usage of CP-8000/CP-802x as SICAM PAS I/O
The devices CP-8000/CP-802x can be used as non-licensed SICAM PAS substations. The
differentiation between normal operation and operation as SICAM PAS I/O is done via a pa-
rameter.
With operation as SICAM PAS I/O, the IEC 60870-5-104 protocol element is defined as a
SICAM PAS I/O interface upon startup. All stations that are connected with this protocol ele-
ment are switched to SICAM PAS I/O mode. A connection with a normally operated station on
the same protocol element is not possible.
Prerequisite for the operation as SICAM PAS I/O is an equipped IEC 60870-5-104 protocol el-
ement (in the following example PRE0 is used).
Set in the directory SICAM A8000 CP-80xx | Master module | Communication | PRE0 the
parameter project specific settings to YES.
Now appears the directory SICAM A8000 CP-80xx | Master module | Communication |
PRE0 | project specific settings. Here you can set the parameter SICAM PAS IO mode to
YES.
For the operation as SICAM PAS I/O the following parameters are relevant:
• SICAM A8000 CP-80xx | Master module | AU common settings
─ Plant
─ Device name
• SICAM A8000 CP-80xx | Master module | AU common settings | common address of
ASDU (CASDU)
─ CASDU1 (must be set equally for all data points)
─ CASDU2 (must be set equally for all data points)
• SICAM A8000 CP-80xx | Master module | Network settings | IP address
─ Own IP address X1/X4
• SICAM A8000 CP-80xx | Master module | PRE0 | Network connection | LAN | IEC 104
parameter
─ Timeout connection setup t0
─ Timeout transmit t1
─ Timeout transmit acknowledge t2
─ Timeout connection check t3
─ Max. no. of APDUs until acknowledgement (k)
─ number of APDUs until acknowledgement (w)
