This information is summarized in matrikon opc explorer Logging pane of the dagroup object properties in the app. Select the Logging tab in the Properties pane. The following figure shows the Logging pane for the dagroup object created in this example.

Using the Logging pane, configure the logging session using the following steps: Set Update rate to 0.

Set Number of records to log to You can leave the rest of the logging properties at their default values, because this example uses data logged to memory. Matrikon opc explorer object is now ready to log the required amount of data to memory.


Click Start in the Logging tab. The progress bar indicates the status of the logging task, as shown in the following figure.

  • MatrikonOPC Explorer | ICS-CERT
  • OPC Server - Does not provide Tags - no data coming through to clients
  • Download Matrikon OPC Explorer
  • Matrikon OPC Explorer (Mobile)
  • OPC Server - Does not provide Tags - no data coming through to clients
  • 403: Forbidden

Note The logging task matrikon opc explorer in the background. Command-Line Equivalent You use the start function with the required dagroup object to start a logging task.

In a more complex task, you would export the logged data to the workspace and use MATLAB functions to analyze and interpret the logged data. When the logging task stops, the Logging matrikon opc explorer will update to show that the task is complete.

An example of the logging status portion of the Logging pane after a completed task is shown in the following figure.

To view the data from the app, click Plot. The matrikon opc explorer of the displayed data and annotation options are controlled by settings in the Plot options frame of the Logging pane. By default, the plot will be annotated with any data points that have a Quality other than Good.

Advisory (ICSA-18-130-01)

Values whos Quality is Bad are annotated with a large red circle with a black border, and Values with Quality of Repeat are annotated with a yellow star. You should always view the Quality returned with the Value of an item to determine if the Value is meaningful or not.

Value, Quality, and TimeStamp. An example of the plotted data is shown in the next figure. Note Your plotted data will almost matrikon opc explorer not look like the one shown here, matrikon opc explorer the logging task was executed at a different time.

Notice how the three signals seem almost completely unrelated, except matrikon opc explorer the period of the two Real8 signals. The peak values for each signal are different, as are the periods for the two Triangle Waves signals. By visualizing the data, you can gain some insight into the way the Matrikon OPC Simulation Server simulates each tag.

In this case, it is apparent that Real8 and UInt2 signals have a different period. Command-Line Equivalent When your logging task has completed you transfer data from the toolbox engine to the MATLAB workspace using the getdata function, matrikon opc explorer provides two types of output, depending on the 'datatype' argument.


For more information see getdata in the reference pages. In this case you retrieve the data into separate arrays, and plot matrikon opc explorer data. The example below reproduces the figure display that you get when you click Plot.

The attacker must have local access to be able to exploit this matrikon opc explorer. CVE has been assigned to this vulnerability. A CVSS v3 base score of 6.
