Remaining Connection Status; Parallel Redundancy Protocol (Prp) - GE B90 Instruction Manual

STATUS
These actual values represent the state of direct devices 1 through 16.

6.3.14 Remaining connection status

ACTUAL VALUES  STATUS  COMM STATUS REMAINING CONNECT
 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.

6.3.15 Parallel Redundancy Protocol (PRP)

6
The Parallel Redundancy Protocol (PRP) defines a redundancy protocol for high availability in substation automation
networks.

The B90 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.
