Valmet DNA controllers

Valmet DNA efficient ACN controller family ensures a dependable platform for all your controls and external connections. These control nodes support the modern ACN I/Os and main industry field buses, such as PROFIBUS, PROFINET, Ethernet/IP, FF and AS-i. Standard links like OPC DA, OPC UA Ethernet and serial links ensure excellent connectivity to third party systems.


The ACN (Application and control nodes) family features a reliable platform for basic and advanced controls, fast logic and versatile calculations.

Valmet's ACN I/O is a modern I/O family used with ACN process controllers. An ACN I/O is suitable for both centralized and distributed I/O solutions.

Fieldbuses have gained ground in controlling intelligent field devices, motors and frequency converters. They can offer improved diagnostics, flexible design and easy commissioning. For instance, improved device diagnostics are integrated seamlessly in the operator’s user interface, or they are available in any web-based user interface. In the Valmet DNA, you will gain a uniform configuration to all fieldbus solutions, easy device parameterization and troubleshooting, online diagnostic window, as well as I/O and bus solutions within just one process controller.


Controllers offer real user benefits, including down to 20 ms control cycles, as well as scalability even to the smallest systems. The same ACN platform is used for connecting third party systems.

Reliability is secured by using industrial components, an advanced spare part concept, redundancy and a stable network structure.
