Remaining Connection Status; Parallel Redundancy Protocol (Prp) - GE M60 Instruction Manual

STATUS
The status information for two channels is shown here.
CHANNEL 1 STATUS
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.
CHANNEL 1 LOST PACKETS
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.

These values specify the remaining number of TCP connections still available for each protocol. The display depends on the
options applicable to your device, for example the PMU entry does not display when not applicable. 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.

— The maximum number of PMU TCP connections matches the number of aggregators. The maximum number of
PMU TCP
aggregators for the N60 is 4. The maximum number for the C60 is 2. The maximum number is 1 for other products with a
PMU. The remaining number of aggregators displays here.

6.2.21 Parallel Redundancy Protocol (PRP)

The Parallel Redundancy Protocol (PRP) defines a redundancy protocol for high availability in substation automation
networks.
