Remaining Connection Status - GE L30 Instruction Manual

6.2 STATUS
PATH: ACTUAL VALUES
 COMM STATUS
 REMAINING CONNECT
These values specify the remaining number of TCP connections still available for each protocol. Every 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 pro-
tocol.
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.
Note that the maximum number of PMU TCP connections matches the number of aggregators.
The Parallel Redundancy Protocol (PRP) defines a redundancy protocol for high availability in substation automation net-
works.
