EtherCAT-ready absolute encoders Model A58HE (hollow bore) and Model A58SE (shaft) are designed for harsh factory and plant environments. Easily designed into a wide variety of applications, these encoders plug directly into a network with minimal prerequisites, and work in various configurations, including daisy-chaining and redundant-ring configurations that can continue communication in event of a line break. The A58E series encoders work with CANopen over EtherCAT, so for users familiar with CANopen technology, implementation will be straight forward. As absolute encoders, they retain absolute position information even after a power loss, facilitating speedy system recovery at start-up without the need for system re-homing.
EtherNet/IP™ is a widely adopted Ethernet communication network that provides users with the tools to deploy standard Ethernet technology (IEEE 802.3 combined with the TCP/IP Suite) in industrial automation applications. The EtherNet/IP and CIP technologies are managed by ODVA, Inc., a global trade and standards development organization.
EtherNet/IP offers various network topology options including star or linear with standard Ethernet infrastructure devices, or device level ring (DLR) with specially enabled EtherNet/IP devices. Compliance with IEEE Ethernet standards provides users with a choice of network interface speeds – e.g., 10, 100 Mbps and 1 Gbps – and a flexible network architecture compatible with commercially available Ethernet installation options including copper, fiber, fiber ring, and wireless.
EtherNet/IP™ implements CIP at the Session layer and above and adapts CIP to the specific EtherNet/IP™ technology at the Transport layer and below. EtherNet/IP uses standard IEEE 802.3 technology at the Physical and Data Link layers. EtherNet/IP can accommodate an unlimited number of point-to-point nodes. At the Network and Transport layers, EtherNet/IP utilizes standard TCP/IP (Transmission Control Protocol/Internet Protocol) to send messages between one or more devices. For real-time data transfer, EtherNet/IP also employs UDP over IP to transport I/O messages that contain time-critical control data.
