Honeywell ControlEdge HC900 Controller 控制器系统

The Honeywell ControlEdge HC900 Controller is an integrated loop and logic controller that is designed

specifically for small-and medium-scale unit operations

It comprises a set of hardware and software modules that can be assembled to satisfy any of a broad range

of process control applications. The ControlEdge HC900 Controller can consist of a single rack, as

indicated in Figure 1, or can be can be networked with other controllers via Ethernet links to expand the

dimensions of control over a wider range of unit processes, as indicated in 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 re

Single process with redundancies

 Redundant CPUs - Redundancy is provided by two C75 CPUs operating in a controller rack; this rack has no

I/O. A Redundancy switch module (RSM) sits between the CPUs.

 Redundant CPU Power - Two power supplies, one for each C75 CPU.

 Redundant CPU-I/O connection – Each CPU has its own 100 base-T Ethernet physical communication link with
