There are two ways to troubleshoot this PLX8x-EIP-61850 gateway:
 Use the LEDs located on the front of the gateway
 Use the Debug port (Ethernet port E1) that provides a view into the gateway's
internal database
4.1 Known Anomalies
In the unlikely event that an IED on the network causes a large number of
reconnects to the gateway, the 61850 driver in the gateway eventually restarts,
causing re-initialization of the communication between the gateway and all the
IEDs on the network. Until all the IEDs connected on the network have been
reinitiated, the data in the gateway database being transferred through the
gateway’s EtherNet/IP is not being updated. To help you detect this condition,
there are status bits available that you can effectively use in the program in the
PLC for tracking. Refer to Driver Status Data on page 58.
4.2 Important Design Considerations
When utilizing any type of gateway device, take care to make sure that in the
event in loss of communications between devices on either driver in the gateway
(the 61850 driver to the IEDs or the EtherNet/IP driver to the processor), this loss
of communications is passed to the other driver.
For example, suppose there is a loss of communications with an IED device on
the 61850 network. This information is shared with the EtherNet/IP device, so
that the device can make an informed decision to trigger any type of alarm or fail
safe state for the attached device.
