The Growth of Fieldbus in the Process Industry

For years the control of processes and machines was a labour intensive operation requiring a large number of people to oversee even relatively simple tasks. Whilst engineering ingenuity led to the development of simple electrical and mechanical devices that allowed much of the manual commitment to be dispensed with, as processes and machines became more sophisticated the amount of control required increased in proportion.

The advent of modern mass production techniques has made it increasingly important for information to be available for use by production engineers and maintenance personnel to enable fault diagnosis and planned/predictive maintenance to take place. Safety concerns also became a major issue that significantly increased the amount of safety related controls in a system.

The introduction of PLC controllers and 4-20mA circuits and devices did much to alleviate pressure on control systems design and manpower commitments, but now the costs involved in implementing process and machine control had risen out of all proportion. The installed cost per device (or node) was increased by the amount of parallel wiring needed for its operation. It became obvious to PLC and control manufacturers that they would benefit from being able to use the same technology for interconnecting devices that was being increasingly used by the emerging PC industry for networking PCs and peripheral devices together.
