EL6751 | CANopen master/slave terminal
The EL6751 CANopen master terminal corresponds to the Beckhoff FC5101 CANopen PCI card. Due to the connection via EtherCAT, no PCI slots are required in the PC. Within an EtherCAT Terminal network, the EL6751 enables the integration of any CANopen devices and can either be master or slave. In addition, general CAN messages can be sent or received – without having to bother with CAN frames in the applications program. The terminal has a powerful protocol implementation with many features:
- All CANopen PDO communication types are supported: event driven, time driven (using an event timer), synchronous, polling.
- synchronisation with the PC controller’s task cycle
- SYNC cycle with quartz precision for drive synchronisation, zero cumulative jitter
- parameter communication (SDO) at start-up and when running
- emergency message handling, guarding and heartbeat
- powerful parameter and diagnostics interfaces
- online bus load display
- bus monitor functionality
The EL6751 is optionally also available as a slave version.
