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.

Previous-generation I/O boards, such as 8RO,

8DO, and 4AO - are all still compatible with E2
I/O Network.

The E2 Echelon Lonworks

Network

The E2 is also compatible with a network platform

called Lonworks. This is most commonly referred to as
“the Echelon Network,” after the company who invented
the platform, the Echelon Corporation.

In general, peripherals with control functions — such

as case controllers, rooftop HVAC controllers, and other
E2 RX and BX units — are interconnected on the Echelon
Network. These controllers do most of their own computa-

tion and system control, but they communicate with other
E2s to provide logging, alarm control, and other functions.
In addition to these, Retail Solutions also offers Echelon-
compatible input and output boards similar to those avail-
able for the RS485 Network.

Figure 1-3 shows the E2 RX peripherals that commu-

nicate across the Echelon Network:

CC-100 - Case control board - controls all lights,

fans, defrost, and refrigeration for a single case. The
CC-100 controls pulse or stepper valves to provide
precise evaporator control, resulting in better tem-
perature maintenance and energy efficiency.

ESR8 - Evaporator stepper regulator - the analog

outputs on this board allow the E2 to control circuit
temperature in up to eight circuits using suction-
side mounted electronic evaporator pressure regula-
tors (EEPRs).

TD3 - Temperature display - has three inputs that

monitor case temperature, product temperature and
defrost status.

Third Party Echelon Devices - Echelon® LON-

MARK® devices communicate with E2 through its
"Open Echelon" networking feature, and require a
license key and a description file that is loaded into
