The Beckhoff ES EtherCAT Terminal Series is a service-oriented subset of Beckhoff’s EtherCAT Terminal platform that uses a pluggable connection level rather than a fixed wiring style.
These terminals follow the same general EtherCAT terminal concept as the EL series, but the field-side wiring can be unplugged from the housing, which makes replacement and maintenance easier. Within the broader EtherCAT Terminal system, the ES series is used alongside couplers and other terminal types that handle signal categories such as digital, analog, encoder, and communication I/O. The series relies on the same 100 Mbit/s EtherCAT communication standard used across Beckhoff’s EtherCAT terminal architecture for real-time automation tasks. In practical terms, the Beckhoff ES EtherCAT Terminal Series is defined more by its removable wiring interface and serviceability than by a separate network or control concept.
