Standardized communication

The 630 series relays fully support Edition 1

of the IEC 61850 standard for communication

and interoperability of substation automation

devices. The relays also support the DNP3

(TCP/IP) and IEC 60870-5-103 communication

protocols and are able to use two protocols

simultaneously. The supported communication

protocols, including IEC 61850. offer seamless

connectivity to various station automation

and SCADA systems.

The implementation of the IEC 61850 standard

covers both vertical and horizontal

communication, including GOOSE messaging

according to IEC 61850-8-1 with both binary and

analog signals. Analog GOOSE messaging enables

fast transfer of analog measured values over

the station bus. This facilitates, for example,

sharing of RTD input values, such as surrounding

temperature, with other relays. GOOSE messaging

is an alternative to traditional hardwiring signaling

for exchanging interlocking information between

the relays. For time-critical applications, the 630

series relays support synchronization over

Ethernet using SNTP or over a separate bus

using IRIG-B.
