The Control Foundation for Modern Industrial Operations

Your operations demand more than basic automation. You need deterministic control that reduces downtime, integrates with existing infrastructure and supports your digital transformation journey.

The Honeywell ControlEdge family of controllers provides connectivity from edge to enterprise, turning data into actionable insight to help customers

improve their bottom line. It enables access to data and control of assets from virtually anywhere, improving efficiency and underlying performance with the lowest total cost of operation. ControlEdge delivers an efficient, scalable solution that offers flexibility to add and remove assets quickly, and consolidates data for operations and analysis for long-term profitability.



Reliable, secure, deterministic control for critical operations

Modular architectures deliver deterministic operation for critical processes. Embedded cybersecurity from development through deployment helps reduce risk and improve compliance.

Frequently Asked Questions About Programmable Logic Controllers

Modular, rack-based architectures like the HC900 support redundancy features designed to achieve fault-tolerant operation for critical applications. Self-diagnostic capabilities enable rapid identification of system errors, while run mode editing and online monitoring support changes with limited process disturbance. The platform enables component removal or insertion under power to maintain process continuity. Built to help support 99.999% uptime targets, the design combines deterministic operation with flexible maintenance approaches that help extend operational lifecycles.

Yes. Universal I/O connects field signals to any channel without additional hardware, accommodating late design changes. The platform supports migration from competitive systems with hot cutover capabilities when offline migration isn't an option. Multi-protocol support (OPC UA, Modbus, Profinet, MQTT) and common HMI with Experion® reduce integration complexity during modernization projects. Honeywell LEAP for Brownfield methodology enables effective transition from existing legacy systems while protecting investments in wiring and networking infrastructure.

Honeywell PLCs integrate with Honeywell Forge APM platforms that create digital twins and apply machine learning to predict equipment failures. The IIoT-ready architecture enables near real-time monitoring and connects operational data with enterprise systems for predictive maintenance workflows. Programming based on IEC 61131-3 standards provides access to modern development approaches. Multi-protocol support facilitates bi-directional data exchange with cloud-based analytics and Industry 4.0 initiatives.
