Overview

This section provides a description of each of the major components that can be included in a
ControlEdge HC900 Controller physical configuration, and indicates some of the methods by which they
can be combined.
2.2.

Components

The Honeywell ControlEdge HC900 Controller includes a set of hardware modules that can be combined
and configured as required for a wide range of small to medium process control applications.
Some of the modules are required in all configurations. Others are optional; they are selected as
appropriate to provide optional functions and/or to "size" the system, either in initial planning, or in
modifying and/or expanding the system to meet changing requirements.
A ControlEdge HC900 Controller configuration with multiple controllers is illustrated in Figure 4.
This illustration includes key-numbers that identify components that are described in Table 1.
Communications lockout is possible in high network traffic conditions.
Extraneous traffic is possible when sharing bandwidth with other devices. We recommend putting the
controller on a private network segment. Failure to do so could, in high traffic cases, result in
communications lockout requiring the controller to be power-cycled.
