Drive connectivity – where is the fieldbus heading

ABB’s Liam Blackshaw gives an insight into fieldbus developments in variable speed drives. Fieldbus options give variable speed drives (VSD) the ability to rapidly and accurately control processes while accessing big data to determine how applications are performing. Among more recent VSD developments is the ability to accommodate two different types of fieldbus modules. This enables a process to be controlled with the most suitable protocol while gathering process data via another route. For instance,…
