6.2.2 IEC-objects of the repeat relays
For each repeat relay and IEC type, an IEC object is generated. All objects are formed identically and
have the same parameters.
Discrete object parameters
„ASDU“
- integer value 0
– 65535 or structured xx-xx (e.g. 11-22).
„IOA“
- integer value 0
– 16777215 or structured xx-xx-xx (e.g. 11-22-33).
„IEC type“
- integer value indicating the respective IEC object type according to standard:
1
single report without timestamp
2
single report with short timestamp
3
double report without timestamp
4
double report with short timestamp
5
step position without timestamp
6
step position with short timestamp
7
32 bit report without timestamp
8
32 bit report with short timestamp
30
single report with long timestamp
31
double report with long timestamp
32
step position with long timestamp
33
32 bit report with long timestamp
45
single command without timestamp
46
double command without timestamp
47
step command without timestamp
58
single command with long timestamp
59
double command with long timestamp
60
step command with long timestamp
For empty fields the value will be set to 0 (no type).
Object parameters selective functions
The respective function can be activated by entering “x” or “X” in the corresponding column.
„Link1 –Link4“ - defines on which link the respective object will be forwarded
„blocked“
- the respective object is blocked, no forwarding on the IEC interface
„double“
- the respective object will be addressed as double command
For empty fields, the respective function is not activated.
Object types
Two object groups are available for communication as IEC server (station) and IEC client (Master).
Object types server communication:
relay
- read relay status
relay set
- set relay status
Object types client communication
The available information objects of the IEC client are identical to the information objects of the IEC
server.
