Group, Has anyone used IEEE 1588 to synchronize clocks on an Ethernet network?
I was involved in the design of time sync for Foundation Fieldbus circa 2000. We needed one millisecond accuracy, so we went with SNTP on local networks. I've just seen an ad for a switch that can do 1588, and looked up what it does. Microsecond accuracy is impressive, but what does it cost? Industrial sensors are generally sampled at about 10 millisecond intervals out to several seconds. SNTP would appear to be very adequate for time stamps as there is uncertainty introduced by when the computer gets around to sampling the sensor in its sampling and control cycle. Any thoughts appreciated.
