EtherCAT Automation Protocol (EAP)

The EtherCAT Automation Protocol (EAP) specifies communication services and protocols for Master devices and Ethernet-based devices connected with a standard Ethernet network.


Standard networks are used for data exchange between devices.
The timing constraints are weaker than for a fieldbus with high real-time requirements but a cyclic communication in the
range of milliseconds is required as well.

The EAP can be used for different use-cases:

  • Master-Master communication
  • Configuration Tool interface
  • Monitoring
  • General Protocol for Data Exchange between devices
