Configuring Foundation Fieldbus Devices via USB PC Connection

A person in the DeltaV LinkedIn group, in a thread, AMS Device Manager and Foundation Fieldbus converters, asks:

I am looking for cost-effective solution for our customer. He needs calibrate FF devices in laboratory ( read data from device ) and he already has AMS DM application. During calibration procedure he needs to work / connect only one FF device ( not whole segment ). Have you solved anybody similar solution in the past? I hope there is possible to use any variant of FF modem ( like HART modem ), but I have a problem to find supplier. I have used google and result was ABB device LD800HSE, but this solution is for coupling several links to one HSE interface ( I think this solution should be expensive ).

On the other side I need solution which is functional ( anybody use it and it works:-) ).

Thanks for information.

Several of the thread responders point to solutions from National Instruments, Softing, and Relcom. Emerson’s Jonas Berge joined the discussion by highlighting a presentation given by Emerson’s Alan Dewey at this past Emerson Exchange conference in Nashville.

Al’s presentation, A Quick and Easy Way to Connect to FOUNDATION fieldbus using Emerson’s USB Fieldbus Interface, describes a means to connect a standard PC or laptop to a Foundation fieldbus segment. He noted that this solution is not intended to be used as a permanent fieldbus Host system.

In the presentation, Al shares some of the capabilities:

  • Fully compliant with Foundation fieldbus specifications
  • PC joins fieldbus segment as visitor
  • Two power modes available—USB powered (to 85mA) and connect with already powered segment
  • Maximum current draw—12mA
  • CE and UL/CSA approvals

This USB interface is currently in beta test and expected to be released in the spring of 2012. It is supported with AMS Device Manager version 11.5 and later. The PC appears under the FF HSE [high-speed Ethernet] branch in the device explorer tree. With the AMS Device Manager HSE license, up to four USB fieldbus interfaces are supported at a time.

Al shared a few things that could be done with Foundation fieldbus instruments through this USB segment connection and included utility program—set power mode, show devices connected to the segment, set device tag, set device address, commission/decommission device, and change device from link master to basic.

Here’s an example screen from Al’s presentation showing how to commission a Foundation fieldbus device from the utility program display:

  1. By far the simplest solution I have used but unfortunately
    not available until April 2012.

    • Ray, Thanks for your comment. Yes, the team was hoping for an earlier release but issues came up in the beta testing that necessitated the revised release date.

  2. Hi,

    Is the USB modem plus AMS Device manager can communicate with other brands like yokogawa and siemens?

    Thanks

    • I checked with my friends on the Asset Optimization team and here’s the feedback I received, “Yes – the USB Fieldbus Interface can communicate with any FOUNDATION fieldbus device supported by AMS Device Manager. This includes Yokogawa, Siemens, etc.”

      • Hi,

        Could you please check with your colleagues if this modem can surely communicate with Yokogawa YTA320 Temp Transmiitter and EJA110E Pressure Transmitter.

        Thanks

        • Adrian;
          As mentioned earlier, the Emerson USB Fieldbus Interface will support all fieldbus devices supported by AMS Device Manager. The Yokogawa YTA 320 is included in our list of supported devices so no problem there. For the EJA, we currently support the EJA100. I notice that the Fieldbus Foundation Site includes an EJA Device but not an EJA110. If these are all the same device, then this device is also supported.
          Also, the USB Fieldbus Interface can diisplay and edit the Tag and Node Address of all fieldbus devcies regardless of thier support by AMS Device Manager.

          • Hi Alan,

            Thanks a lot for the information. Is the National Instrument PCMCIA FBUS can be also use as FF modem in the AMS Device manager to communicate ff instruments? Or only Emerson USB FF interface can be used for standalone setup?

  3. Dear All,

    I bought a hart Modem with model USB HK-UH100 from China (BEIJING HUAKONG TECHNOLOGY CO., LTD), Also I had AMS application, but it can not communicate with AMS. So Could you please advise me or instruct me how to configure the AMS to it can shake hand with the Modem? Thank you very much for your kind supports.

  4. Dear Jim, i have AMS installed, i try to use with the USB-8486 NI fieldbus interface, but i don’t make it work, when i try to add with the network configuration App i don’t see the NI device in the options, can you help me please!!!

    Kind regards.

    Daniel.
