What is VoE in EtherCAT?

VoE is the abbreviation for Vendor over EtherCAT. It is a protocol that allows manufacturers to implement their own proprietary communication protocols over an EtherCAT network.

This flexibility enables vendors to create custom solutions tailored to specific application requirements while still leveraging the high performance and real-time capabilities of the EtherCAT protocol.
