Fieldbus Technology

Foundation fieldbus helps meet regulatory and profitability challenges

The technology simplifies field-level communications and provides new functionality

Glanzer, D. A., Fieldbus Foundation

Today, fieldbus – a general term for digital communications protocols that allow devices in the field, such as transmitters, analyzers, etc., to communicate bidirectionally with control systems – is providing oil and gas producers and processors with a valuable tool to meet business challenges. For example, fieldbus' multidrop capabilities (the ability to attach numerous field devices to a single fieldbus connection) and the self-diagnostic capabilities of fieldbus instruments simplify network topologies and aid in maintenance tasks. Those are big advantages in an industry dependent on remote, unmanned offshore platforms or vast onshore oil fields in difficult-to-reach areas.
