Honeywell ControlEdge HC900 Controller



Honeywell ControlEdge HC900 Controller 

Overview

The ControlEdge HC900 controller is an advanced circuit and logic controller with a modular design that can meet the control and data management needs of various process equipment. Highly integrated with the optional 900 Control Station operator interface, it minimizes configuration and setup time, combined with Honeywell's proven control technology, providing an ideal solution for process control. Open Ethernet connection supporting Modbus TCP protocol, allowing network access using multiple HMI/SCADA software, and program execution environment protected by independent watchdog timers.

Application Fields

Widely used in industries such as mining and metals, chemical, pharmaceutical, railway/infrastructure, HVAC/data centers, pulp and paper, cement and glass, electricity, etc. Specific equipment includes furnaces, kilns, boilers, extruders, high-pressure sterilizers, sterilizers, dryers, combustion management, combustion control, emergency shutdown systems, pipeline monitoring, leak prevention systems, etc.

Functional Features

Redundancy support: Supports separate rack redundancy, redundant and non redundant architectures for secure universal I/O, controller redundancy, etc.

Communication function: Supports HART IP protocol and can communicate with Honeywell FDM (Field Device Manager); Support HART function block; Supports Modbus TCP protocol for Ethernet communication, enabling peer-to-peer communication; Support email alerts/event messages, etc.

Control function: Equipped with advanced PID loop control and Accutune III automatic tuning function; Support multiple control algorithms and logic function blocks; Support sequence event recording (SOE), etc.

Configuration and programming: Use Windows based Designer software for configuration, supporting multiple languages; Process configuration changes can be made in operating mode while maintaining process control; Provide rich reporting functions, etc.

Storage and Memory: Adjustable square pool memory, which can be allocated for recipes, set point curves, sequences, and scheduling; Use flash memory to store user configuration programs, battery backup memory for dynamic data storage, etc.

Other functions: Supports hot plugging of I/O modules; Equipped with LED indicator lights to display digital I/O status; Support configuration of graphic function blocks; Equipped with extended alarm and event monitoring functions.

Architecture

Non redundant architecture: including single process/single rack (process), single process/single rack (safety), single process/multi remote rack (safety), multi process/multi rack (process), multi process/multi rack (redundant network star topology), multi process/multi rack (redundant network ring topology), etc.

Redundant architecture: Two redundant C75 CPUs run in separate controller racks, each with an independent power supply. The redundant switching module (RSM) is located in the rack between the two C75 CPUs, and the CPUs communicate with up to 12 I/O racks through 100base-T Ethernet physical communication links or optical fibers with external media converters.

CPU module

Models: including C30 and C50 (non redundant applications), C70 (dual network), C75 (redundant CPU applications and dual network).

Architecture and Memory: Based on the e300 32-bit RISC architecture, PowerPC, C30, and C50 modules use 64MB DDR2 memory, while C70 and C75 modules use 128MB DDR2 memory. All modules' DDR2 memory supports ECC circuits, enhancing reliability and error detection capabilities.

Communication: All CPU modules provide open Ethernet communication, and C70 and C75 offer dual Ethernet ports for high network availability installations.

Scanning method: Adopting a dual scanning method to process fast digital scanning and normal analog input scanning in the same integrated control environment.

I/O modules and scanners

I/O module types: including various analog input modules, analog output modules, digital input modules, digital output modules, pulse/frequency/orthogonal I/O modules, etc., with different points and isolation characteristics.

I/O scanner: Remote I/O is processed through the remote I/O scanner module and communicates with the main CPU module. There are single port models (for non redundant CPU systems) and dual port models (for redundant CPU systems).

Hot swappable: Supports removing and inserting I/O modules while powered on for easy maintenance.

Terminal block: Provides 20 screw terminal blocks with barrier or Euro style screw connections. Some high-capacity modules require 36 screw Euro style terminal blocks.
