Figure 2 – Expanded ControlEdge HC900 Controller Configuration (C50/C70 CPU only)
The ControlEdge HC900 Controller design enables users and OEMs who are adept in system integration
to assemble a system that fits a broad range of requirements. Any configuration can be readily modified
or expanded as requirements dictate. In initial configuration and in subsequent modifications, the
ControlEdge HC900 Controller affords an optimum balance of performance and economy.
Configurations such as those shown in Figure 1 and in Figure 2, as well as many variations, can be
assembled from modular components. Many of the components are available from Honeywell, and some
are available from third-party suppliers. These modular components are available in any quantity and mix
that make the most sense for a given application.
As indicated in Figure 3, the ControlEdge HC900 Controller includes provisions for communication via
Ethernet with host systems such as the Honeywell Experion HMI and other HMI software that supports
Ethernet Modbus/TCP protocol. Also, the communication structure of the ControlEdge HC900
Controller enables remote placement of input/output components, allowing significant economies in
cabling and wiring.
