Ability Symphony Plus Distributed Control System Accelerates Digitalization


The Ability Symphony Plus distributed control system (DCS) is designed to support digital transformation for power generation and water industries. The latest version of Symphony Plus will help support customers’ digital journey through an OPC UA1 connection to the edge and cloud, without interfering with core control and automation functionalities.


Symphony Plus delivers customers access to digital solutions, such as fleet asset management enabled by ABB Ability Genix Asset Performance Management. It also enables users to access process and alarm data from mobile devices through the ABB Mobile Operations application.


Critical data can be viewed anywhere, anytime thanks to HTML5 web-based operation and engineering tools. Flexible field device management has also been enabled with ABB’s Field Information Manager (FIM) making the configuration, commissioning, diagnostics, and maintenance of fieldbus instruments quicker and easier. A newly added SD Series e-Class process controller offers a low-risk, low-disruption retrofit solution for traditional Harmony Rack (HR) installations.


Symphony Plus is backward compatible with all previous generations of the Symphony family of distributed control systems: Network 90, INFI 90, INFI 90 OPEN, Symphony Harmony, Contronic, and Symphony Melody
