External I/O (Modbus RTU master)
External Modbus I/O devices can be connected to the device
using this protocol. (See chapter 8.6.2 for more information).
6.2.9.
IEC 61850
The relay supports communication using IEC 61850 protocol
with native implementation. IEC 61850 protocol is available
with the optional inbuilt Ethernet port. The protocol can be
used to read / write static data from the relay or to receive
events and to receive / send GOOSE messages to other relays.
IEC 61850 serve interface is capable of:
Configurable data model: selection of logical nodes
corresponding to active application functions
Configurable pre-defined data sets
Supported dynamic data sets created by clients
Supported reporting function with buffered and unbuffered
Report Control Blocks
Supported control model: direct with normal security
Supported horizontal communication with GOOSE:
configurable GOOSE publisher data sets, configurable
filters for GOOSE subscriber inputs, GOOSE inputs
available in the application logic matrix
Additional information can be obtained from the separate
documents ―IEC 61850 conformance statement.pdf‖, ―IEC
61850 Protocol data.pdf‖ and ―Configuration of IEC 61850
