What is FOUNDATION Fieldbus?

PROFIBUS PA and FOUNDATION Fieldbus are the only fieldbus systems that are accepted in process engineering. These systems are developed for the optimization and replacement of conventional systems such as 4-20 mA and HART. However, FOUNDATION Fieldbus has a different philosophy compared to PROFIBUS PA regarding functionality and protocol. Whereas instruments are the most important elements in a PROFIBUS system given that everything is connected, with Fieldbus the controller is the most crucial, for which the appropriate instruments are chosen. FOUNDATION Fieldbus is primarily used in South America, Asia and the Middle East, while PROFIBUS is used more in Europe.

The top benefits of FOUNDATION Fieldbus are: ideal for process engineering, explosion protected and control in the Field.

Basic principles

In many cases, the controller for FOUNDATION Fieldbus is a DCS system that exchanges information according to the master-slave method, and in rare cases Control in the Field whereby the process is distributed across the field instruments. The cabling technique is identical to PROFIBUS PA (MBP according to IEC 61158-2).

The PROCENTEC ComBricks– alongside PROFIBUS – is suited to monitor FOUNDATION Fieldbus and to remotely inspect the results via Ethernet.
