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.
The settings menu for the fast EGD exchange is shown below:

Fast exchanges (50 to 1000 ms) are generally used in control schemes. The G60 has one fast exchange (Exchange 1) and
two slow exchanges (Exchanges 2 and 3).

Slow EGD exchanges (500 to 1000 ms) are generally used for the transfer and display of data items. The settings for the
fast and slow exchanges are described below:
• EXCH 1 DESTINATION: This setting specifies the destination IP address of the produced EGD exchange. This is usu-
ally unicast or broadcast.
• EXCH 1 DATA RATE: This setting specifies the rate at which this EGD exchange is transmitted. If the setting is 50 ms,
the exchange data will be updated and sent once every 50 ms. If the setting is 1000 ms, the exchange data will be
updated and sent once per second. EGD exchange 1 has a setting range of 50 to 1000 ms. Exchanges 2 and 3 have a
setting range of 500 to 1000 ms.
