3.1 615/620 series implementation
3.1.1 Internal IEC 61850 data modeling
The protective relay is natively using the IEC 61850 data model for data processing. In
practice, some data which is not used by the system database might not be available.
Furthermore, the data must be enabled in an IEC 61850 dataset to be able to be reported
by IEC 60870-5-101/104.
3.1.2 Instances
The protocol can be run as multiple instances. Each instance has its own database and
therefore all the data accesses are independently managed. For example, if a client is not
available for event receiving, that does not affect the data buffering for other clients.
Every instance has independent configuration and data object mapping. It is possible to
build a configuration where the amount of information objects is different for the clients.
For example, a client with slow connection gets only the most important data.
3.1.3 Selecting between IEC 60870-5-101 and IEC 60870-5-104
All available protocol instances support both the IEC 60870-5-101 and IEC 60870-5-104
communication. The communication is selected in the
Port configuration parameter.
3.2 Configuring
Some parameters are applicable only to either one of the protocols.
It is assumed that all the other settings have their default values. Avoid
changing the other settings unless something is clearly wrong by default.
