- Periodic reading of values (polling)
- Reading of values from predefined Datasets made available in predefined Information Reports - both buffered and unbuffered
- Reading of array elements which are simple values
- Writing to simple types of values (writing to structures is not implemented yet)
- Writing to array elements of which are simple values
- Writing - control according to the "Select Before Operate With Enhanced Security" model
- Browsing - when communication is established, the following items can be browsed:
...
The protocol was tested with:
- software simulators
...
...
- ABB Feeder protection and control REF615
- communication adapter ABB SPA-ZC 400
Note for ABB SPA-ZC 400: when adding objects to the dataset (in Communication Enginering Tool for SPA-ZC40x), it is necessary to check the option "Export Datasets DO Level" so that the entire object (e.g. Pos) is added as one structured variable (otherwise, its components are added as independent report items, e.g. Pos$stVal, Pos$q, Pos$t).

| Maximum size of MMS messages. Some ABB devices need to increase this parameter (e.g. to 100,000) because they do not support sending a list of objects (GetNameList message) in parts. | bytes | 32000 | ||||||
| Maximum proposed transactions that could be sent and unacknowledged. The value can be reduced if the other party suggests a lower value at negotiation. | 1 .. 32 | 5 | ||||||

| Timer, which permits the sending of an ICCP message Identify request to the communicating party to find out the validity of TCP/IP connection. To enable the timer a nonzero value must be specified. If the connection was aborted on the TCP/IP level, fast detection ensures its faster restoration. | sec | 0 | ||||||

| The parameter enables specifying additional names of objects to query during browsing for I/O tags. Names must be separated by a space, e.g. "Obj1 Obj2".

OperTm - if the option is checked, the optional item $operTm is also written to (the value 0 is written) for the SelectWithValue/Operate/Cancel write types. The $operTm item is always written for the TimeActivatedOperate write type (time of the written value).
Note:
- for WriteType = Select, the Name must end with the string $SBO, e.g. CBCSWI1$CO$Pos$SBO
- for WriteType = SelectWithValue/Operate/Cancel/TimeActivatedOperate, the Name must end with the string $ctlVal, e.g. CBCSWI1$CO$Pos$SBOw$ctlVal (SelectWithValue/TimeActivatedOperate), CBCSWI1$CO$Pos$Oper$ctlVal (Operate), CBCSWI1$CO$Pos$Cancel$ctlVal (Cancel)

For the I/O tags, it is possible to find a list of objects and their data types, as long as the KOM process is running and communication is established.
When a Browse button is clicked, the IEC61850 Browser window opens, and the KOM process begins to query the list of objects with the GetNameList-Request message and then their data types with the GetVariableAccessAttributes-Request message.
