Watlow EZ-ZONE ® RME Module • 8 • Chapter 1 Overview
A Conceptual View of RM Hardware Configurations
Due to the scalability and flexibility in the system
components a user has several options available in
the way that the hardware can be connected. Listed
below are a few examples.
RM System Connected to a Remote User Interface
(RUI) and a PC
In this configuration the RUI and PC are connected
to the RM system via Watlow's Standard Bus where
both will be able to talk directly to any interconnect-
ed system module.

The PC running EZ-ZONE Configurator software
and the RUI can be used to configure and then moni-
tor both modules.
RM System Connected to a Programmable Log-
ic Controller (PLC) on a DIN Rail
In this configuration the PLC can be connected to
the RM system via the Access module using one or
more available protocols:
1. EtherNet/IP and or Modbus TCP
2. DeviceNet
3. Modbus RTU
4. Profibus DP

RM System Connected to an Operator Interface
Terminal (OIT) through an RUI/Gateway
In this configuration the HMI can be running any
of a number of protocols communicating to the RM
system through Watlow's RUI/Gateway. Available
protocols for the RUI/Gateway follow:
1. EtherNet/IP and or Modbus TCP
2. DeviceNet
3. Modbus RTU
4. Profibus DP

RM System Connected to a Split Rail with OIT
In this configuration both the Inter-module Bus
(backplane communications) and Standard Bus are
connected between rails to allow for remote capabili-
ties. It is recommended that the split rail connection
not exceed 200 feet. In this configuration the OIT
can communicate with all modules (maximum 16
modules any combination with one Access module).
