6.2.17 REMAINING CONNECTION STATUS
PATH: 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, for example the PMU entry does not display when not applicable. Each time a con-
nection 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.
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
of 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.
6.2.18 PARALLEL REDUNDANCY PROTOCOL (PRP)
The Parallel Redundancy Protocol (PRP) defines a redundancy protocol for high availability in substation automation net-
works.
PATH: ACTUAL VALUES  STATUS  PRP
The L30 Line Current Differential System is provided with optional PRP capability. This feature is specified
as a software option at the time of ordering. See the Order Codes section in chapter 2 for details.
TOTAL RECEIVED PORT A is a counter for total messages received (either from DANPs or from SANs) on Port A.
