Gateway Testing with Distributed Test Manager(DTM)

Use Case

Gateways are commonly used to distribute controls and data across different parts of SCADA systems. These devices are often used to concentrate thousands of data points from hundreds of devices and translate messages across multiple protocols. Because of their large scope, testing gateways can be time consuming and error prone.

Today, many protocol mapping tests for gateways are performed manually. Each point is tested, one by one, to ensure data is mapped correctly. This manual approach may be required in final site acceptance testing, but preliminary configuration testing in the lab can be automated by simulating the field devices and SCADA system with valid protocol messages.

This allows the real gateway to be tested within a simulated test system, which can automatically run through all data points and document the results of the protocol mapping. This approach is faster and more reliable than manual testing. In addition, it can allow testing to be performed earlier rather than waiting for the final system to be installed and configured.

Automated Gateway Testing for web

To learn how to automate testing of your SCADA Gateway, Data Concentrator or Protocol Converter, watch this short training video for step by step instructions.


  • Rapidly deploy accurate simulations of each IED within your SCADA network
  • Quickly specify thousands of point-to-point gateway tests across single or multiple protocols
  • Execute thousands of individual tests and view detailed results in real-time
  • Use both default and custom Gateway Test Actions
  • Quickly scale up test coverage by exporting Gateway Test Actions for several points to Excel and replicating to a large number of points

Example: IEC 61850 to DNP3 Mapping Verification

This example demonstrates how to test the mapping of a SCADA gateway or RTU in an automated test environment.

In this example, Distributed Test Manager (DTM) simulates multiple IEC 61850 IEDs and a single DNP3 SCADA Master. This simulates the real environment that the gateway can be tested within. Automated tests are generated by repeatable actions. DTM runs these automated tests in order to validate the configuration of the gateway and document the results. In this example, the Triangle MicroWorks SCADA Data Gateway is the device under test.

This example illustrates how DTM can be used to test partial systems without requiring all components in place and configured.  It also shows that this type of testing can be performed without expensive test equipment to generate signal changes.

This same test can be performed for standard SCADA protocols like ICCP/TASE.2, IEC 60870-5 (-101 or -104), DNP3, IEC 61850, and Modbus.

This video demonstrates using the Distributed Test Manager to validate mappings.
