USING THE IEC 61850 CONFIGURATOR
NOTE:
NOTE:
4-28
An Ethernet connection is required for programming relays using the IEC61850 Device
Configurator; connecting to the relay via USB is not recommended.
For details on establishing an Ethernet Connection please refer to "SR3 GOOSE
configuration - Lab".
3 Series GOOSE implementation
Before we proceed we will review the 3 Series IEC61850 implementation. The 3 Series
family of relays can receive and transmit both digital and analog information. However,
currently only digital status information received via GOOSE can be used within the
3 Series relays.
Transmission data block
Each 3 Series relay has one GOOSE transmission data block consisting of up to 64 data
items. Once configured, this block is transmitted at power-up, on a pre-configured time
basis (ranging from 1 to 60 seconds) and within a window of 4 to 10 ms after a digital point
within the data block has changed state.
Reception data blocks
Each 3 Series relay has eight GOOSE receive data blocks. Each receive data block consists
of up to 64 data items and is configured to receive the transmission from a specific device
on the network. Received digital status information from any of the eight receive data
blocks is mapped into the local relay's 32 remote digital input locations such that this
status can be used by the local relay.
The total number of items that can be received is affected by the number of GOOSE
receives that have been configured, the type of data item, and by whether or not the
quality is to be received with the item.
