CHAPTER 6: ACTUAL VALUES STATUSF60 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL 6-1166.3.21 Incipient fault detectorACTUAL VALUES STATUS INCIPIENT FAULT INCIPIENT FAULT 1(2)The number of detected incipient faults for each incipient fault element are displayed here for each phase. These valuescan be reset to zero with the COMMANDS CLEAR RECORDS CLEAR INCIPENT FAULT COUNTERS command.6.3.22 Remaining connection statusACTUAL VALUES STATUS COMM STATUS REMAINING CONNECTThese values specify the remaining number of TCP connections still available for each protocol. The display depends on theoptions 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, thenumber 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 computerconnected to the UR over Ethernet, the Modbus TCP status shows 3. If the EnerVista application is closed, the Modbus TCPstatus shows 4.MMS TCP — The number of IEC 61850 connections remaining.PMU TCP — The maximum number of PMU TCP connections matches the number of aggregators. The maximum number ofaggregators for the N60 is 4. The maximum number for the C60 is 2. The maximum number is 1 for other products with aPMU. The remaining number of aggregators displays here.6.3.23 Parallel Redundancy Protocol (PRP)The Parallel Redundancy Protocol (PRP) defines a redundancy protocol for high availability in substation automationnetworks.ACTUAL VALUES STATUS PRP STATUS INCIPIENT FAULT 1 INCIPIENT FAULT 1PH A FAULTS: 0Range: 0 to 65535 in steps of 1 INCIPIENT FAULT 1PH B FAULTS: 0Range: 0 to 65535 in steps of 1 INCIPIENT FAULT 1PH C FAULTS: 0Range: 0 to 65535 in steps of 1 COMM STATUS REMAINING CONNECT MMS TCP(max 5)5Range: 0 to 5 MODBUS TCP (max 4)4Range: 0 to 4 DNP TCP(max 2)2Range: 0 to 2 IEC-104 TCP(max 2)2Range: 0 to 2 PMU TCP1Range: 1 to 4 SFTP (max 4)4Range: 0 to 4 PRP STATUS Total Rx Port A: Range: 0 to 4G, blank if PRP disabled Total Rx Port B: Range: 0 to 4G, blank if PRP disabled
