An open controller (not to be confused with an open-loop controller) is a control system that has multiple processors embedded into the controller itself. Because of this, open controllers are able to run both ladder logic and windows-based applications inside a singular enclosure. The consolidation of these processes allows for flexibility, giving your controller the ability to run, monitor, and access a plethora of applications. Below, we’ll address a few of the most prominent applications of a Siemens open controller in contemporary factories and discuss the advantages an open controller may offer your company in the long run.
