ETHERNET Powerlink (EPL) is a deterministic real-time protocol for standard Ethernet. EPL expands Ethernet with a mixed polling and time-slicing mechanism that brings:

a) Guaranteed transfer of time-critical data in very short isochronous cycles with a configurable response time

b) Time-synchronization of all nodes in the network with sub-microsecond precision

c) Transmission of less time-critical data in a reserved asynchronous channel

DSPowerlink is an EPL (Ethernet Powerlink) network card that can be used either with a DSPCG motion controller or independently, in PCI card form, with user PC software. In either configuration, it provides 100 Mbps of real time Isochronous network speed for remote I/O and motor drive applications.
