PRODUCT SETUP
EGD cannot be used to transfer data between UR series relays. The relay supports EGD production only. An EGD exchange
is 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. The default setting value of "0" is considered invalid.
Fast exchanges (50 to 1000 ms) are generally used in control schemes. The C30 has one fast exchange (exchange 1) and
two slow exchanges (exchange 2 and 3).
The settings menu for the fast EGD exchange follows.

 CONFIGURATION
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 as follows.
EXCH 1 DESTINATION
unicast or broadcast.
— This setting specifies the rate at which this EGD exchange is transmitted. If the setting is 50 ms, the
EXCH 1 DATA RATE
exchange data is updated and sent once every 50 ms. If the setting is 1000 ms, the exchange data is 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.
EXCH 1 DATA ITEM 1 to 20/50
from the C30 memory map can be configured to be included in an EGD exchange. The settings are the starting Modbus
register address for the data item in decimal format. See the Modbus memory map in the UR Series Communications
Guide for details. The Modbus memory map display shows addresses in hexadecimal format. Convert these hex values to
decimal format before entering them as values for these setpoints.
