Introduction - Functional Description
Figure 2 – Expanded HC900 Controller Configuration (C50/C70 CPU only)
The 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 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 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 HC900 Controller enables remote
placement of input/output components, allowing significant economies in cabling and wiring.
