If a pure CANopen master connection is required without slave operational modes configured in your software environment, ensure your TwinCAT System Manager software is updated to recognize the differences in the hardware description files (ESI XML) between standard EL6751 modules and the EL6751-0010 variant.

Ensure total network branch lengths do not violate standard CANopen cabling limits. At 1000 kbaud, keep segment lines shorter than 40 meters.

The EL6751-0010 does not provide switchable internal bus termination.
