6.3.20 Incipient fault detector
ACTUAL VALUES
STATUS
INCIPIENT FAULT
INCIPIENT FAULT 1(6)
The number of detected incipient faults for each incipient fault element are displayed here for each phase. These values
can be reset to zero with the

CLEAR INCIPENT FAULT COUNTERS
command.
6.3.21 Remaining connection status
ACTUAL VALUES
STATUS
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.
MMS TCP
— The number of IEC 61850 connections remaining.
6.3.22 Parallel Redundancy Protocol (PRP)
