 CLIENT ADDRESSES
The G30 can specify a maximum of five clients for its IEC 104 connections. These are IP addresses for the controllers to
which the G30 can connect.
A maximum of two simultaneous connections are supported at any given time.

The G30 Generator Protection System is provided with optional Ethernet Global Data (EGD) communica-
tions capability. This feature is specified as a software option at the time of ordering. See the Order Codes
section in chapter 2 for details.
The relay supports one fast Ethernet Global Data (EGD) exchange and two slow EGD exchanges. There are 20 data items
in the fast-produced EGD exchange and 50 data items in each slow-produced exchange.
Ethernet Global Data (EGD) is a suite of protocols used for the real-time transfer of data for display and control purposes.
The relay can be configured to 'produce' EGD data exchanges, and other devices can be configured to 'consume' EGD
data exchanges. The number of produced exchanges (up to three), the data items in each exchange (up to 50), and the
exchange production rate can be configured.
EGD cannot be used to transfer data between UR-series relays. The relay supports EGD production only. An EGD
exchange will not be transmitted unless the destination address is non-zero, and at least the first data item address is set to
a valid Modbus register address. Note that the default setting value of "0" is considered invalid.
