data is being received from the remote terminal; If the value is "FAIL," teleprotection enabled and data is not being received
from the remote terminal. If "n/a," teleprotection is disabled.

The number of lost packets represents data packets lost in transmission; this count can be reset to 0 through the

check, and hence validity. If a remote relay ID does not match the programmed ID at the local relay, the "FAIL" message
displays. The "N/A" value appears if the local relay ID is set to a default value of "0," the channel is failed, or if the
teleprotection inputs/outputs are not enabled.

ACTUAL VALUES  STATUS  COMM STATUS REMAINING CONNECT
 COMM STATUS
 REMAINING CONNECT
These values specify the remaining number of TCP connections still available for each protocol. The display depends on the
options applicable to your device. Each time a connection is used, the remaining number of connections decrements.
When released, the remaining number of connections increments. If no connection is made over the specific protocol, the
number equals the maximum number available for the specific protocol.
For example, the maximum number of Modbus TCP connections is 4. Once an EnerVista session is opened on a computer
connected to the UR over Ethernet, the Modbus TCP status shows 3. If the EnerVista application is closed, the Modbus TCP
status shows 4.
For the graphical front panel, the remaining connections refer to TCP connections only.
