Honeywell ControlEdge HC900 Controller Overview

The Honeywell ControlEdge HC900 Controller is an advanced loop and logic controller featuring a 

modular design tailored to meet the control and data management requirements of diverse process 

equipment. When paired with the optional 900 Control Station operator interface—seamlessly 

integrated with the controller’s database—configuration and setup time are significantly minimized. 

This powerful combination, combined with Honeywell’s field-proven control technology, delivers an 

ideal solution for process control applications. Equipped with open Ethernet connectivity via Modbus 

TCP Protocol, the controller enables flexible network access using various HMI/SCADA software 

platforms. Its program execution environment is safeguarded by an independent watchdog timer, 

ensuring reliable operation.

The controller is supported by intuitive Windows-based Designer software, operable over Ethernet or 

an isolated RS485 port, which streamlines configuration tasks. Available in English, Chinese, Russian, 

and German, the software offers advanced monitoring capabilities for debugging, supports run-mode 

process configuration changes without disrupting process control, uploads complete annotated 

graphic controller configurations, and provides a suite of reports to enhance documentation. Beyond 

superior PID loop control and robust analog processing—outperforming most logic controllers 

without compromising logic performance—the HC900 features a dedicated fast scan cycle for 

executing a comprehensive range of logic and calculation function blocks. For time-critical events, 

logic blocks can also run in the same scan as analog function blocks, allowing full integration into 

combined analog and logic control strategies to achieve uncompromising control performance.

Applications

Key Configuration & Monitoring Features of Honeywell ControlEdge HC900 

Controller

●Graphic drag-and-drop and soft-wire configuration for intuitive setup.

●Configures both the controller and operator interface, supporting peer-to-peer data exchange, data 

storage, recipes, setpoint profiles, schedules, and sequences with online operation, as well as alarms, 

events, and e-mail warning setup.

●Enables function block configuration partitioning using worksheets, with support for up to 400 

configuration pages.

●Allows download of configuration edits in Run mode without disrupting ongoing process control.

●Comprehensive configuration upload, including graphic configuration, interface assignments, and 

annotations for complete documentation.

●Extensive online monitoring tools: watch windows, multiple block access, and signal trace-back for 

efficient debugging and process oversight.

●Dedicated online diagnostic windows to analyze controller, I/O, network host, and controller peer 

connections.

●Flexible connectivity options: Ethernet, RS232 direct, or RS232 modem connection.

●Displays power flow indication for digital signals and pins for clear status visualization.

●Supports viewing of function block I/O values on a per-pin, per-function block, or per-viewable 

window basis for targeted monitoring.

●Facilitates uploading, editing, storing, downloading, and printing of individual recipe files, setpoint 

profiles, schedules, and sequences for convenient data management.
