Welcome to the DLMS Test Platform.

A knowledge sharing portal for DLMS testing & certification

Achieving DLMS Certification

The DLMS UA provides a series of test tools that members can use to complete the DLMS UA Qualification Process and obtain the DLMS UA Certification of Compatibility and/or Certification of Compliance.

These certifications guarantee that certified products are fully compliant with the internationally recognized DLMS/COSEM Standard and any other International Standardization bodies having adopted it such as IEC with the IEC62056 Suite or ANSI with their C12 Suite of Standards and are compatible with other certified DLMS products.

To find out more about the Qualification Process please visit the Qualification Portal here.

Test Tools

The CTT - Compliance Test Tool (previously known as the Standard CTT)

The CTT should be used when DLMS UA Members want to complete their DLMS UA Qualification Program application for certifying their candidate device. This Test Tool has been developed with the intent to permit DLMS UA Members to test autonomously their candidate device. At the end of each full test cycle the Test Tool will produce an accredited test report file to be submitted during the DLMS UA Qualification Program application.

The CTT is a software that implements the Abstract test cases (ATSs) as Executable Test Suites (ETSs). It runs on a PC under 64 bit Windows 7, Windows 8.1 or Windows 10 (from CTT 3.0 V108). The CTT acts as a DLMS/COSEM test client whereas the Implementation Under Test (IUT) acts as a DLMS/COSEM server. The CTT allows the selection, parametrization and execution of the ETSs using the information taken from the Conformance Test Information (CTI) file and the information obtained by the CTT from the IUT. The CTT supports the DLMS/COSEM 3-layer, connection-oriented HDLC based communication profile and the TCP/IP based communication profile. In addition, DLMS UA has developed a substantial number of additional Communications Profiles supporting the most popular wired and wireless communication technologies from which the Member can choose from.

The DTT - Development Test Tool (previously known as the Extended Test Tool)

The DTT gives more detailed access to all the log scripts during the process of testing. The DTT also supports a trace mode that allows the user to break the testing at specific points to focus on problem areas. This makes the DTT a more flexible and user-friendly tool for developing new products and correcting any alignment issues with the DLMS/COSEM specifications.

The DTT is the ideal tool for product developers wishing to gain a greater depth of understanding with their product performance and testing.
The DTT is a software that implements the Abstract test cases (ATSs) as Executable Test Suites (ETSs). It runs on a PC under 64-bit Windows 7, Windows 8.1 or Windows 10 (from DTT 3.0V108) and offers similar functionalities to the CTT, but in much greater depth.

Golden Devices

"Golden Devices" provide DLMS UA members with a defined test bench configuration with which to test unique transport layers.
The Golden device is used in conjunction with the CTT or DTT and the device under test. The CTT/DTT is designed to recognize the Golden Device configuration so that only accredited devices and any corresponding firmware and software can be used.
The uniformity of the test conditions means that the corresponding certificate is traceable to a known standard.

DLMS UA provides “Golden Devices” for members to use within their test bench. This is to ensure that test cases that require specific data compression for low bandwidth communications or test cases that require unique transport layers can be tested using the DTT or CTT with accredited devices that give a traceable test result to known test conditions and configurations.

Golden Device configurations are available with versions of the Test Tool from version 4.2 and later.

The Test Tool allows selection of the relevant transport layer within the configuration of the tool. The Test Tool then recognizes the Golden Device configuration and compares this configuration with the accredited parameter list.
