6.2.4.
External I/O (Modbus RTU master)
External Modbus I/O devices can be connected to the relay
using this protocol. (See chapter 8.6.1 External input / output
module for more information).
6.2.5.
IEC 61850
IEC 61850 protocol is available with the optional
communication module. IEC 61850 protocol can be used to read
/ write static data from the relay to receive events and to
receive / send GOOSE messages to other relays.
IEC 61850 server 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
interface.pdf” on our website.
