Overview
The PerformanceAlert™ Gateway is designed to allow
the Emerson Climate Technologies Retails Solutions fam-
ily of site controllers (E2, Einstein, and REFLECS) to in-
terface directly with up to 14 Copeland
PerformanceAlert™ Diagnostic Modules.
The Gateway uses two network ports: one, a MODBUS
port used to connect the Gateway with the Perfor-
manceAlert™ modules, and the second an I/O network port
that connects the Gateway to the I/O network of an E2 or
Einstein control system (or COM A/D of a REFLECS net-
work).
The Gateway mimics the behavior of a MultiFlex 16 in-
put board, passing along data from the PerformanceAlert™
modules about compressor behavior to the site controller in
the form of virtual board/point addresses. The Gateway's
board/point addresses may be used by the site controller for
I/O control, logging, and alarming.

Figure 1-1 - Typical Layout of PerformanceAlert™ Modules and
Gateway Board
A typical layout of a CPC-controlled Perfor-
manceAlert™ network configuration is shown in Figure 1-
1. Each compressor in each rack is equipped with one Per-
formanceAlert™ Diagnostic Module. All modules are
wired together in a single MODBUS daisy-chain and con-
nected to the PerformanceAlert™ Gateway board. The
Gateway Board is also connected to the E2 via the I/O net-
work, where it mimics the behavior of a MultiFlex input
board (16AI) and sends values from the modules to the E2
as virtual board/point addresses.

which maps a single 16AI point to the alarm status of each
PerformanceAlert™ module, and an Expanded Mode,
which maps sixteen 16AI points for each module, includ-
ing alarm status for all alarm types, current transducer val-
ues, and discharge line temperature.

Mode, the PerformanceAlert™ Gateway mimics the equiv-
alent of up to fourteen 16AI boards.
