Click"GOOSE" in the main interface to enter the GOOSE message detection page.
GOOSE messages can be accessed from any of the three optical ports, and click"F1: Refresh" to detect the GOOSE messages that are currently connected.
Serial number: Show GOOSE control block by serial number;
Port: to determine the current GOOOSE control block is from the optical port 1, optical port 2 or optical port 3 access, display the corresponding port number;
IED Name: The received GOOSE message automatically matches the SCD file. If the match succeeds, the corresponding IED name is displayed. If it does not match, the display will show "/". When click"F2: Display Switch" and "IED Name" Displays the MAC destination address of the GOOSE message;
APPID: Display the APPID of the GOOSE control block;
Inspection results:When the received GOOSE message matches the SCD file and displays the IED name, then click"F3: Consistency Check" to check whether the GOOSE message parameter matches the SCD file. If it is consistent, check the result bar display; if not, check the result bar display. Clickorto view the consistency checklist, as shown in Figure 5.4-1.

Data serial forwarding: series in the optical fiber link mode of operation, does not affect the flow of fiber data, but also access to data normal analysis, instrument function can be used normally.
Press "F4: string to close (optical network port)" to open the optical port data serial forwarding function, optical port 1 or optical port 2 received data from the optical port 2 or optical port 1 forward each other.
Click"F5: string into the closed (optical serial port)", open the serial data serial data forwarding function, RX received data from the TX port at the same time
From the "GOOSE detection page", click the GOOSE control block or click the "up" and "down" arrow keys to select the GOOSE control block (the selected GOOSE control block background color is yellow), click the "ENTER" key to enter the selected GOOSE control Block the virtual terminal test page.
The "virtual terminal" test function includes the GOOSE virtual terminal list, the GOOSE virtual terminal status indication chart, the GOOSE virtual terminal traversal graph, and the GOOSE virtual terminal change flipping time record table, and click the "F1: list""F2: status indication" F3 : Traverse the graph "" F4: Flip time "You can switch the four function pages of the virtual terminal test.
GOOSE virtual terminal list: "GOOSE virtual terminal list" real-time display GOOSE virtual terminal channel type and status value, if the virtual terminal channel status changes, the state value data immediately refresh, and automatically jump to the variable data page, while changing Bit data value background display red. Real-time display of the status number StNum of the GOOSE message per frame and the serial number SqNum in order to observe the GOOSE virtual terminal data change.
GOOSE virtual terminal status indication chart: "GOOSE virtual terminal status indication chart" in each of the grid map corresponds to a virtual terminal, when the single point of data is "1" or double point data is "10", the square background red. When you click the grid chart, the channel name, type, and current status value for the corresponding virtual terminal are displayed at the bottom of the page.
GOOSE virtual terminal traversal diagram: "GOOSE virtual terminal traversal diagram" to view the way real-time display GOOSE virtual terminal within 90 seconds of data state transition situation, when the single point of data is "1" or double-point data is "10" The lines in the view are displayed as square bars.
GOOSE Virtual terminal change Flip time record table: "GOOSE virtual terminal change rollover time record table" records the moment of virtual terminal change, record the time difference between the last change time and record the status of the change channel (such as records Channel status from False → True)
