Remaining Connection Status - GE B30 Instruction Manual

CHAPTER 6: ACTUAL VALUES

6.3.19 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.
— The number of IEC 61850 connections remaining.

6.3.20 Parallel Redundancy Protocol (PRP)
The Parallel Redundancy Protocol (PRP) defines a redundancy protocol for high availability in substation automation
networks.
ACTUAL VALUES  STATUS  PRP STATUS
 PRP STATUS

The B30 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.
is a counter for total messages received (either from DANPs or from SANs) on Port A.
Total Received Port A
is a counter for total messages received (either from DANPs or from SANs) on Port B.
Total Received Port B
is a counter for total messages received with an error (bad port code, frame length too short).
Total Errors
is a counter for total messages received with an error on Port A (PRP frame, but port received through
Mismatches Port A
and LAN ID in the frame do not match).
