Extended functions

EoE (Ethernet-over-EtherCAT)
Explanation of the EoE function in the EL6692: When the operating system (Windows) is instructed to send
an IP frame (e.g. to 192.168.2.1), it uses a broadcast to all available network adapters to determine through
which adapter the destination address can be reached. The EL6692 transports this broadcast, which
reaches it through acyclic mailbox communication it to the other side, which responds based on its network
mask.
AoE (ADS-over-EtherCAT)
ADS (Automation Device Specification) is a Beckhoff-specific protocol for data exchange between hardware-
or software-based devices. The configuration of these ADS telegrams is described in the Beckhoff
Information System. AoE is a VoE (vendor-specific protocol over EtherCAT). The EL6692 can transport ADS
telegrams to the other side directly (AoE), i.e. without underlying IP channel.
To this end the EL6692 must be entered in the System Manager as an ADS gateway; see the following
sample (https://infosys.beckhoff.com/content/1033/el6692/Resources/zip/2460148491.zip)
Two PCs with TwinCAT 2.10, b1340 and an EL6692 with Firmware 05 are used.

Both PCs send 10,000 bytes of data each to the other side. An Ads-Write is used on the sender side and the
Indication/Response method on the receiver side. To this end, the target AmsNetId must be entered in both
System Manager configurations so that, for sample, the ADS router in PC1 can reach the ADS device
'192.168.2.1.1.1' via the 'channel' EL6692.
The procedure is as follows on the primary side; the secondary side (PC2) follows suit.
