Ethernet Communication
The GLP safety relay is equipped with optical communication via optical link.
With the optical link, diagnostic data can be read from the GLP safety relay
and transferred to other devices over an EtherNet/IP network.
Figure 28 - Arrangement of EtherNet/IP Network Interface and GSR Relays
The catalog number 440R-ENETR EtherNet/IP network interface must be in
the left-most position. The EtherNet/IP network interface automatically
determines the models present and their position. Up to six GSR relays can be
mounted next to the EtherNet/IP network interface. See publication
440R-UM009
for further details on the EtherNet/IP network interface.

The GLP safety relay provides the following data on the EtherNet/IP network
interface webpage. To access the webpage, connect an Ethernet cable to your
computer and type in the Ethernet address.
