3.1.6 Addressing
3.1.6.1 Addressing of Automation Units
Each device CP-8000/CP-802x forms an automation unit and is addressed with
• Region number (0…249)
• Component number (0…255)
Within a system-technical plant, the automation unit must be uniquely addressed, which
makes the maximum size of a system-technical plant 64000 automation units.
3.1.6.2 Addressing of Process Information
Addressing and the structure of the process information to be passed on by CP-8000/CP-802x
are consistent with the IEC 60870-5-101/104 standard. Therefore, the information is in turn
compatible and interoperable with many other vendors.
In the automation network, each data point is addressed by means of
CASDU 1………Common address of ASDU, octet 1
CASDU 2………Common address of ASDU, octet 2
IOA 1……………Information object address, octet 1
IOA 2……………Information object address, octet 2
IOA 3……………Information object address, octet 3
TI………………..Type identification
3.1.7 Time Management
3.1.7.1 Clock
Generally, CP-8000/CP-802x supports automatical time tagging for all data. On the Master
Module resides the central clock of the automation unit.
Time tagging takes place automatically at each point in the system where spontaneous data
originates. Data is transferred priority-controlled, in standard protocols with 7 octet date and
time with resolution of 1 ms.
