There is a considerable amount of confusion when it comes to understanding what a host system really is, and how we test and register them at the Fieldbus Foundation. The Foundation defines different classes of hosts based on their functionality. Integrated hosts, for example, are what we would typically think of as a fully functional DCS host with HMI, plant asset management, and engineering and configuration capabilities. Other hosts include those used strictly for maintenance purposes. The Foundation has defined sets of functionality that we test for for each class of host. To demystify this whole process, we have created a white paper that outlines the various types of hosts that are offered and their respective functions and testing requirements. You can download the paper in PDF format at the Foundation web site.
