Honeywell ControlEdge HC900 Controller system

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

one or more racks of I/O. Multiple I/O racks require Ethernet switches.

 I/O racks – 5 racks shown, top to bottom: 4-slot w/1 power supply, 8-slot w/1 power supply, 12-slot w/1 power

supply, 8-slot w/redundant power supplies, 12-slot w/redundant power supplies. A Power Status Module (PSM) is

required with redundant power supplies. High and low capacity power supplies are available.

 Redundant Networks for Host communications - Redundant Networks for Host communications are provided on

the C75 CPU. Both network ports are continuously active on the Lead controller. The network ports on the Reserve

CPU are not available for external communications. Experion HS and the 900 Control Station (15 inch model)

support redundant Ethernet communications and automatically transfer communications during a network failure.

 Scanner 2 module – has 2 ports, one for each CPU connection to I/O.

Feature Summary

Hardware

 Modular rack structure; components are ordered individually as needed

 CPU with Ethernet communications

 Easy to assemble, modify, and expand

 Local (C30 and C30S) and Remote input/output racks (C50/C70), private Ethernet-linked sub-network

 Parallel processing - a microprocessor in each I/O module performs signal processing, to preserve update

rates

 Power supplies - provide power to CPU rack and Scanner I/O rack

Redundancy

 Redundant C75 CPU

 Redundancy Switch Module (RSM) – required between redundant CPUs

 Redundant Power Supply – provides redundant power to any CPU rack or Scanner2 I/O rack

 Power Status Module (PSM) – required when using a second power supply in Scanner2 I/O rack

Communications

All CPUs (except where noted):

 Serial ports

 In legacy systems, two serial ports, RS-232 or RS-485 can be configured.

 In new systems, two RS-485 ports can be configured.

 PC Configuration Tool

 In legacy systems, RS-232 port used for link to PC configuration tool (up to 50 feet or 12.7 meters) or

modem. Port configurable as Modbus RTU/TCP master or slave.

 In new systems RS-232 to RS-485 cable is used for link to PC configuration tool.
