Honeywell ControlEdge HC900 Controller 控制器系统

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.
