Network Diagram with Equipment Controllers

Integration to the Metasys system

supervisory devices

The CG and CV series equipment controllers are designed

to integrate seamlessly into the Metasys system by

connecting to, communicating with, and being supervised

by Metasys network engines (including SNE, SNC, NAE,

NIE, and NCE series network engines). 

This seamless integration of equipment controllers with

Metasys network engines delivers coordinated, system-wide

control and enables building operators to monitor and

adjust equipment controllers from the Metasys system UI.

In addition, service personnel can view equipment

controller information locally through an optional local

controller display (MS-DIS1710-0) available for equipment

controllers, or through the optional Mobile Access Portal

(MAP) Gateway.

Communications protocols

The CGM and CVM controllers can communicate using

BACnet MS/TP, N2. or wireless Zigbee. The controllers

auto-detect the protocol that is connected, which enables

the same controller to support multiple communication

protocols without the need to purchase a special model

per protocol, and without extra manual setup.

The XPM expansion modules can communicate using

BACnet MS/TP, or wireless Zigbee® using a ZFR/ZFR Pro

Wireless Field Bus Router (on the FC Bus only). By default,

the XPM expansion modules communicate using the

BACnet MS/TP protocol.

The BACnet MS/TP protocol is a standard for ANSI,

ASHRAE, and the International Standards Organization

(ISO) for building controls.

The CGM and CVM controllers can be used as functional

replacements for legacy N2 controllers. The N2-capable

MS/TP equipment controller models provide a cost

effective upgrade and modernization path for customers

with existing N2 controllers.

The CGM and CVM controllers can also be installed in a

wireless application using a ZFR/ZFR ProWireless Field Bus

Router, see Related products.
