CVT — Configuration Validation Tool
CVT automates system tests for substation automation: generate test cases from the SCL file, simulate IEDs, run the tests and produce a test report suitable for FAT.
Application
CVT supports the IEC 61850 and IEC 60870-5-104 interfaces as well as the connection to the IPS-20 test system. A typical application is testing RTUs and gateways: CVT simulates the IEDs on the station bus and checks the telegrams towards the control centre as an IEC 60870-5-104 client.
Because test creation and execution are separate, tests can be carried out independently after a short introduction. Experienced testers save time because tests run quickly and several components can be tested at once.
Workflow
Import the SCL file, select test case templates and signals, generate the test.
Start the IED simulation based on the SCD file.
Tests run automatically one after the other, complete or selectively.
Filter results in the test report, output it as PDF and archive it.
The software
Test data is created from the imported SCL file. You select test case templates, add the matching signals and adjust parameters such as timeouts, IOAs or measurement ranges. One click generates the test assembly.
Tests can also be built for a reduced data set, for example for a single IEC 61850 client.
Tests are organised by use case and bay. Run the complete test set or repeat individual tests, for example only those that failed.
Each result is stored automatically with a time stamp in the test set.
The Test Report Configurator combines all results of a test set into one report. Filters show warnings and errors at a glance; each test is documented down to the telegrams sent and received.
With time stamps and this level of detail, the report is suitable as a FAT test record and can be output as PDF.
More functions
All IEDs of an SCL file can be simulated. CVT writes the required IP addresses to the network adapter automatically and restores the previous configuration afterwards.
A test set bundles configuration, simulation, test runs and reports. Test sets can be exported, backed up and reused on another PC.
Deviations are classified with error codes, such as a missing telegram, an unexpected value or a wrong RTU control model.
The log view shows the output of all CVT components. The Sentinel log viewer with filter functions supports detailed diagnostics.
A tabular description of all test methods with test steps and exchanged signals is included.
The interface to IPS-20 brings electrical process signals into the system test.
At a glance
CVT needs no setup: the program folder is simply copied to the target system.
