Overview

Chapters

• 00:00 - 00:30: Introduction In the introduction, Brian Trace, the product manager for fieldbus and remote I/O products at Pepperl+Fuchs, introduces the topic of the discussion: the components that make up a complete Foundation Fieldbus segment. He begins by mentioning that the first component in any Foundation Fieldbus segment is a host.
• 00:30 - 01:30: First Component: Host and H1 Interface The chapter discusses the structure and components of a foundation fieldbus segment, focusing initially on the H1 interface as the first component. The discussion briefly mentions subsequent components, such as the fieldbus power supply and field distribution, before addressing individual field devices.
• 01:30 - 03:30: Second Component: Foundation Fieldbus Power Supplies The chapter discusses the integration of Foundation Fieldbus Power Supplies into various DCS systems such as those from Delta V, Yokogawa, and Honeywell. It highlights that the host system, regardless of the manufacturer, is central to control operations. Additionally, it introduces the concept of the Link Active Scheduler (LAS) which is crucial for managing the schedule of the field bus network.
• 03:30 - 05:00: Third Component: Field Distribution – Segment Protector and Field Barrier The chapter discusses the components of a Foundation Fieldbus system, focusing specifically on the power supplies. It provides an example of the Peplow and Fuchs power hub, highlighting its features such as four segment options and redundant supplies. The top part of the system displays four host connections with redundant host options and redundant bulk power supply inputs.
• 05:00 - 05:30: Conclusion The chapter focuses on trunk connection power supplies, highlighting their importance in providing matching impedance for field bus segments. It emphasizes that without proper power supply, communication signals would be lost, making control of the plant unfeasible. Additionally, it touches on the availability of various power supplies from different manufacturers.

• 00:00 - 00:30 [Music] hi i'm brian trace ik i'm the product manager for field bus and remote i/o products here at pepper ellen Fuchs today we're going to discuss the components that make up a complete foundation fieldbus segment the first component in any foundation fieldbus segment will be a host the
• 00:30 - 01:00 second component will be a foundation fieldbus power supply you then move down your trunk cable into a field distribution we call them segment protectors and from there you go off to your individual field devices so the first component in any foundation fieldbus segment is the h1 interface here you see a typical two-port h1
• 01:00 - 01:30 interface connected into a delta V controller and this could be with any dcs system Yokogawa Honeywell it's independent of manufacturer but the host is where all of your control will will be done and this is where the LA S or the link active scheduler is housed which controls the schedule for the rest of the field bus network the second component that makes up a
• 01:30 - 02:00 foundation fieldbus segment would be the foundation fieldbus power supplies this is an example of Peplow and Fuchs power hub there are different numbers of segment options this is a four segment redundant supply at the top here you'll see we have 4 host connections with redundant host an option redundant bulk power supply inputs and down here you
• 02:00 - 02:30 have 4 segments for your trunk connection power supplies main goal is to provide a matching impedance for the field bus segment if you just connected up a bulk power supply your communication signal would be lost and there would be no no viable communication to control your plant now the various power supplies available from different manufacturers offer
• 02:30 - 03:00 redundancy of the power supplies as well as usually a built in selectable terminator each foundation fieldbus segment needs 2 terminators wanted D each end of the segment and so having it built into your power supplies is a convenient way to make sure that that's included another option included on the power hub is our advanced diagnostic module this built-in module allows you
• 03:00 - 03:30 to monitor the physical layer for all 4 foundation fieldbus segments and it's signal is transmitted through a diagnostic bus right from the backplane the next component for a foundation fieldbus segment is going to be some sort of field distribution and for Peplow and Fuchs we call that a segment protector this is what takes a trunk in connection from your power supplies and
• 03:30 - 04:00 converts that into different spur connections for your individual field devices the segment protector offers a short-circuit protection as well as some LEDs to tell you if there's an error or to let you know that you have communication and power additionally built into the segment protector is the second Terminator that you need for your foundation fieldbus segment so again it's already included
• 04:00 - 04:30 with the segment protector and makes it easier to to ensure that you have two per segment additionally you can daisy chain multiple segment protectors together using the trunk in and trunk out connection and these are used for safe area or division two applications another option for field distribution when using the high-power trunk concept is the field barrier this is a Division
• 04:30 - 05:00 two mountable zone one mountable interface that provides you with four intrinsically safe outputs for use in class 1 div 1 or zone 0 applications it provides again short circuit protection for the individual Spurs as well as the optional terminator so today I've shown you the three major components that make up a foundation fieldbus segment the
• 05:00 - 05:30 hosts the power supplies in the field distribution for more information on these solutions such as data sheets white papers or application notes visit our website thank you for your time you
