Overview

The DDLS 538 ... S2 ... is designed for transferring EtherCAT data. The data is transferred transparently
similar to an Ethernet cable connection.
NOTICE
The DDLS 538 ... S2 ... does not generate any data of its own, has no integrated EtherCAT
slave controller (ESC) and is a non-addressable "infrastructure component" for the EtherCAT
master.
The following EtherCAT communication profiles can be transferred by the DDLS 538 ... S2 ...:
• EtherCAT protocol: cyclical IO data
• EoE: Ethernet over EtherCAT
• CoE: CANopen over EtherCAT
• FoE: File access over EtherCAT
• AoE: ADS over EtherCAT
• EAP: EtherCAT Automation Protocol
• SoE: Servo drive profile over EtherCAT
• FSoE: Fail Safe over EtherCAT
The DDLS 538 ... S2 ... can be used in all topology variants supported by EtherCAT. The depicted simpli-
fied network topology can be used in part or on a larger scale.
