8.9.3 Device Level Ring (DLR)
The devices support DLR. The Device Level Ring (DLR)-redundancy protocol is used to increase
the stability of EtherNet/IP networks. DLR-enabled devices have an integrated switch and can
thus be integrated into a ring topology. The DLR protocol is used to detect an interruption in
the ring. If the data line ins interrupted, data are sent through an alternative network section, so
that the network can be reconfigured as soon as possible. DLR-capable network nodes are
provided with extended diagnostic functions which enable the devices to localize errors and
thus decrease the time for error search and maintenance.
8.9.4 Diagnostic messages via process data
The diagnostic messages of the IO-Link-channels are directly mapped into the process data
[}108].
Additionally, the device's status word contains the module diagnostics:
