SI-POWERLINK
  • Overview
  • Specifications

Unidrive, Commander, Digitax and the Pump Drive families can now connect to all POWERLINK networks. SI-POWERLINK

SI-POWERLINK serves applications ranging from simple open-loop systems through to those demanding precise motion control.

POWERLINK is a communications protocol based upon standard Ethernet and provides a solution for real-time industrial Ethernet to satisfy the requirements of industrial automation and process control. High-speed, deterministic response times are ensured via a mix of timeslot and polling procedures.

POWERLINK is used in applications in industries including automotive, energy management, machinery, industrial automation, railway and maritime transportation, robotics, vision systems and many more.
