Yokogawa Fieldbus pH/ ORP Transmitter/ Analyzer
What is Fieldbus?
Fieldbus Foundation defines "Fieldbus is a digital, two-way, multi-drop communication link among intelligent measurement and control devices." It is one of several local area networks dedicated for industrial automation. The Internet is having a major impact on information flows. Yesterday's hierarchical systems the field signals used in process instrumentation have been standardized so that control systems and field devices from a variety of suppliers can be interconnected using standard 4 to 20 mA analog signals. A "standardized" digital communication for industrial automation is changing the production system.
The FOUNDATION™ fieldbus standard developed by the Fieldbus Foundation™ constitutes the next level of standardization and it is designed to meet modern needs. In addition to having interconnectivity equivalent to that available using 4 to 20 mA analog signals in a conventional field network, FOUNDATION™ fieldbus allows multiple devices to be connected to a single FOUNDATION™ fieldbus, permits the interactive communication of various types of information, and enables the distribution in the field of intelligent functions including self-diagnostics and control functionality.
When FOUNDATION™ fieldbus was first proposed, more attention was given to its ability to convey multiple field signals over a single cable and the benefit this would have in reducing wiring costs. But now the focus is on its ability to transmit various types of information in addition to field signals and to distribute intelligence to distributed field devices. These features enable remote monitoring, real-time self-diagnostics, and proactive maintenance of field devices, as well as plant resource management using field communication. This will enable the costs of operating instrumentation systems to be greatly reduced.
