New FOUNDATION Fieldbus system engineering guidelines

16 October 2012

The Fieldbus Foundation has release of a major revision to its AG-181 System Engineering Guidelines.

AG-181 is a comprehensive guide that includes best practices and recommendations for a complete FOUNDATION fieldbus installation –from engineering and design through commissioning, startup, operations, and maintenance. The guide includes recommendations on topics from selecting cable to wiring installation, grounding, implementing plant asset management systems, and best practices for project management.

The new edition of AG-181 has been reformatted and reorganised to make it easier to read and access information. Some content has aslo been rewritten to include more up-to-date information. This includes sections covering the Fieldbus Intrinsically Safe Concept (FISCO) fieldbus design rules, cable length, surge protection and segment scheduling. A section on the use of existing wiring has also been added.

According to Larry O'Brien, global marketing manager for the Fieldbus Foundation, the FOUNDATION fieldbus System Engineering Guidelines is "one of the automation industry's best-kept secrets" that belongs in the library of almost every process control engineer. It is a highly valuable resource for the growing number of end users, system integrators and engineering firms involved in the implementation of FOUNDATION fieldbus.”
