[ ] Ethernet Lnk Con Dia
Status
This actual value appears when the relay is ordered with the Ethernet (T) option.
The actual value message indicates the status of the Ethernet link,
ETHERNET STATUS
connection, and diagnostic via three indicators. The
symbol indicates off. There is also a blinking indication.
The box under column indicates the Ethernet link status. If it is on, the Ethernet port is
LNK
connected to the network; if it is off, the port is disconnected. This indicator is normally on.
The box under the column indicates the connection status. If on, the Ethernet port is
CON
configured and ready to transmit and receive data. If blinking, the Ethernet port is either
active (transmitting or receiving data) or indicating an error if the diagnostic status is also
on or blinking.
The box under the column indicates the diagnostic status. If it is on, then either a fatal
DIA
Ethernet port error has occurred or there is a duplicate IP address on the network. If
blinking, then there is a non-fatal network error. Off indicates no errors.
