Foundation Fieldbus


Thread Starter


We have a huge base of installation for FF devices.

One of the long pending issue we are facing is: Devices are indicating in field but are OFFNET as per status in Honeywell EPKS DCS.

We have replaced the Field Connex Field Barrier but problem still persists.

If anyone had faced such issue or can guide me, it will be of great help.

Thanks & Regards,
Wow, great HART troubleshooting document.

For those who don't download the document, they should know that it is probably the best HART troubleshooting document I've ever encountered.

Because it assumes a HART handheld (375/475), it misses some issues with HART modems running software on a Windows box, but for general it covers a great deal.

The listing of bands for grades of signal and noise levels was very interesting.
