GOOSE Analyzer Operator's Manual
The reserved value range for GOOSE type 1 is 0x0000 to 0x3FFF. For GOOSE type 1A
(Trip), the reserved value range is 0x8000 to 0xBFFF. If no APPID is configured, the
default value is 0x0000. This default value indicates the lack of configuration.
It is recommended to use a unique, source-orientated GOOSE APPID within a system.
For more detailed explanation of APPID, refer to Annex C.2 in the IEC standard IEC
61850-8-1.
The APPID analyzer compares the APPID contained in the received GOOSE message
(packet) with that in the SCD based on the reference of the GOOSE control block. In
normal status, the APPID conforms to the value in the configuration.
When an APPID mismatch is detected, the analyzer issues a specific diagnostic event
to warn users of the status transition.
VLAN ID analyzer
VLAN specification restricts the data flow of multicast messages to those IEDs that need
the messages. This way the load over a switched network can be optimized. VLAN
specification is handled in the switches and it needs the switches to support it.
The value range for VLAN is 000 to FFF.
The VLAN ID analyzer compares the VLAN ID contained in the received GOOSE
message (packet) with that in the SCD based on the reference of the GOOSE control
block. In normal status, the VLAN ID conforms to the value in the configuration.
When a VLAN ID mismatch is detected, the analyzer issues a specific diagnostic event
to warn users of the status transition.
VLAN user priority analyzer
User priority can help guarantee real-time performance, especially in a burst situation.
User priority is handled in the switches and it needs the switches to support it.
Priority value is between 0-7, where a higher number indicates a higher priority message,
which is handled in the priority queues of the switches (vendor specific). 4 is the
recommended value for GOOSE.
VLAN user priority analyzer compares the user priority contained in the received GOOSE
message (packet) with that in the SCD based on the reference of the GOOSE control
block. In normal status, the user priority conforms to the value in the configuration.
When a user priority mismatch is detected, the analyzer issues a specific diagnostic event
to warn users of the status transition.
