IEEE 1588-2008 Protocol

    Last Modified: August 1, 2019

    The internal Ethernet switch can be configured to act as a 1588 "boundary clock" implementing the IEEE 1588 delay request-response default PTP profile (sometimes referred to as "default profile"). When so configured, it can synchronize local measurement signals to other devices across an IP subnetwork and can serve as a bridge, synchronizing 1588 devices that are attached to each of the two ports. Refer to Synchronization across a Network for more details.


    The IEEE 802.1AS protocol is an IEEE 1588 profile, but is incompatible with other IEEE 1588 profiles. When FieldDAQ devices are using the IEEE 802.1AS protocol to synchronize they cannot synchronize with devices that use other protocols or IEEE 1588 profiles and vice versa.
