Exlar's New CANopen Communication Protocol Enhances Motion Control Capabilities

Exlar Tritex™ II with CANopen Communication Protocol

Chanhassen, MN—Exlar Corporation, a Curtiss-Wright company located in Chanhassen, MN, announces the release of the CANopen communication protocol for its Tritex II product line. This enhancement allows the Tritex II to become an integral part of your control architecture or machine control processes.

CANopen is now available on Tritex II AC and Tritex II DC actuators. The Tritex II with the CANopen network is intended to perform as a Slave with a CANopen Master. It does not have the features of a standalone indexer like other Tritex models. Setup of the system is most easily achieved with the Expert software using the RS485 port. The latest revision of the Expert software supports all the Tritex products including CANopen and is available on the Exlar website for download.

Customer connections for CANopen are offered with either an M12 connector or wired directly to a terminal strip on the connection board with 75, 90 and 115 mm frame sizes.
