Bulletin 842E-CM Integrated Motion on EtherNet/IP™ Absolute Encoders are designed for motion control applications that require feedback-only axes. These encoders support the standard motion instruction set in the Studio 5000™ Logix Designer application. By providing auxiliary feedback directly through an EtherNet/IP network, these encoders eliminate the need for point-to-point wiring. You can use them in a variety of network topologies such as linear, ring, or star. These encoders leverage CIP Sync, a time synchronization extension that is fully compliant with IEEE 1588.
