Features and Benefits
Remote User Interface/Gateway (RUI/GTW)
• Uses one RUI for multiple zones
• The RUI without a gateway card utilizes minimal
panel depth allowing it to fit in small spaces
• Eliminates the costs and complexity of having to
bring all controller related wires to the front
panel
• Enables the use of multiple RUIs to improve the
system’s usability and flexibility

Using the RUI/GTW 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
• Profibus DP
The networks see the gateway and RUI as separate
devices. Both sides (1 port on each side) of the gate-
way will require unique addresses based on the proto-
col specifications.

Note:
Excessive writes through the gateway to other EZ-
ZONE ® family controllers may cause premature
EE-PROM failure. For more detail see the section
entitled “ Saving Settings to Nonvolatile Memory .”
Note:
A Standard Bus network can communicate with a
maximum of eight RUIs with up to four of those
being gateways. Valid Standard Bus addresses for
RUIs equipped with the gateway option are 1, 2, 3
or 4. As is always the case each RUI must have a
unique Standard Bus address.
