The combination of proven DeltaV control software and server-based compute platforms delivers a unique solution that offers greater flexibility, seamless scalability, enhanced resiliency, and extensible operations.
Flexible
Easily scale to meet future needs.
Extensible
Add or upgrade components with no interruptions.
Resilient
Greater uptime with increased fault tolerance.

DeltaV IQ Controller – The Future of Control Is Software Defined
Take Advantage of the Most Flexible Automation Architecture DeltaV has Ever Delivered
Introducing the DeltaV IQ Controller – the next evolution in process control technology. Designed to augment highly engineered, built-for-purpose industrial controllers, the IQ Controller brings greater flexibility, scalability, and efficiency to modern control systems.
By deploying control workloads within a server-based environment, the IQ Controller simplifies engineering, maintenance, and upgrades while significantly reducing footprint and increasing scalability.
With more control capacity than a traditional DeltaV controller, a single pair of servers can handle the control requirements of most large-scale facilities, transforming industrial automation like never before.
Smarter, Scalable, and More Powerful Control
The DeltaV IQ Controller leverages cutting-edge technology to deliver unmatched control performance for all types and sizes of applications. By abstracting proven DeltaV control software from the traditional controller hardware platform, the IQ Controller provides a flexible system that minimizes the hardware requirements and footprint by allowing users to load multiple controllers on a single host.
Increase or decrease the number of controller instances used according to demand. With flexible licensing, you only pay for the controllers you need—when you need them.
The DeltaV IQ Controller minimizes initial expenses by reducing the need for cabinets and controller wiring. Its easy scalability lowers the cost of late-stage changes, while subscription licensing helps reduce capital expenditures.
Run multiple IQ Controller instances on one pair of hosts. This streamlined platform minimizes power consumption, wiring, and cabinet requirements.
The DeltaV IQ Controller supports 1:1 redundancy on separate independent hosts for increased availability.
How It Works
Fully Integrated
- The IQ Controller uses the same engineering and operations tools as traditional controllers.
- Use DeltaV Virtual Studio to easily manage IQ Controller instances through the entire controller lifecycle.
High Availability
- Easy Redundancy – DeltaV Virtual Studio automatically creates redundant partners on separate servers.
- Increased Resiliency – Redundant partners can be dispersed over short distances for greater uptime.
Simplified Simulation
- Easy Synchronization – There is no need to create “virtual” IQ Controllers – it’s already virtual.
- Seamless Integration – DeltaV IQ Controller integrates directly with DeltaV Simulate. Support for DeltaV SimulatePro coming soon.
