panel
• Enables the use of multiple RUIs to improve the
system’s usability and flexibility

Using the RUI as a Gateway
The addition of a gateway card allows information to
be passed from the Standard Bus side of the gateway
(EZ-ZONE-family controllers) to one or more of the
following popular field bus networks:
• EtherNet/IP™
• DeviceNet™
• Modbus TCP
• Modbus RTU
The networks see the gateway and RUI as sepa-
rate devices. Both sides of the gateway will require
unique addresses based on the protocol specifications.

Controllers
Note: Excessive writes through the gateway to other EZ-ZONE
family controllers may cause premature EEPROM failure. For
more detail see the section entitled “Saving Settings to Non-
volatile Memory.”
Note: A Standard Bus network can communicate with a maxi-
mum of four gateways or a maximum of eight RUIs. If the net-
work includes both gateways and RUIs, each gateway address
displaces an RUI address. Therefore, if the network includes
four gateways, it can accomodate no more than four RUIs.
