Motion Controllers With PowerLink (EPL) Interfcae
PowerLink Motion Controller
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:
- The DSPowerlink guarantees transfer of time-critical data in very short isochronous cycles with the configurable response time.
- Time-synchronization of all nodes in the network with sub-microsecond precision.
- 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.
