E2 I/O Network

Most of the general purpose input and output commu-
nications devices required by the E2 to control refrigera-
tion systems are connected to the E2 via the I/O Network.
The I/O Network is a simple RS485 three-wire connection
that allows data interchange between input boards (which
read sensor values and digital closures), output boards
(which carry out commands from E2's control applica-
tions), and the E2 itself.
The I/O Network is the same thing as the COM A and
COM D Networks found on Emerson Retail Solutions'
previous generation of controllers, REFLECS. This allows
current owners of Emerson Retail Solutions' Refrigeration
Monitor and Control (RMC) or Refrigeration Monitor and
Case Control (RMCC) controllers to easily retrofit with an
E2 RX without need for re-wiring.

Figure 1-2 shows the peripherals that make up the I/O
Network:
• MultiFlex - The MultiFlex line of control system
boards provide a wide variety of input, output, and
smart control solutions, all of which are based on a
single universal hardware platform.
• 8ROSMT - Relay output board - activates and deac-
tivates up to eight devices.
