I would like to inquire whether it is possible to communicate via the ETS board hardware, for example, to access the DUT's web server. The aim would be to use it to perform functions such as updating the DUT's firmware or retrieving operating information without having to constantly reconnect the ...

Using the Automated Runtime Tester sometimes the test result PassWithHint is reported? Could you explain this result a bit more.


A PassWithHint is generated, in case a value is allowed, but not the recommended value defined in the PROFINET specification. The resulting hint is put in the test ...

Webinar_Question wrote: ↑24 Nov 2025, 09:41 What IO device cycle rate is being used for the Security Class 2/3 testing?

The cycle rate is dependent on the capabilities of the DUT and has to be configured individualy.
Currently 8ms is the fastest cycletime that is used on the ETS.

Is it possible to set/change the cycle rate of the ETS tester for in House tests?


Currently it is not possible to adjust the cycle rate. Some Testcases modify the cycle rate and/or iterate through the possible cycle rates. It would be quite problematic in certification to guarantee the usage of ...

Sometimes "Get MAC-Adress" does not work - what could be the reason? (Connection to ETS is established!)


The "GET MAC-Address" feature is using the LLDP packets to find the different MAC-Addresses. We try to wait as long as possible, but we need an LLDP packet to be recieved at the ETS.

Our custom PowerOutlet DLL is not recognized/selectable in ART Tester 2.46.0.205 under Windows 11. It seems to be Windows
specific, because the same PowerOutlet DLL is working with the same ART Tester version on a Windows 10 computer.

The DLL was generated with the .NET 8 framework and Visual ...

What could be the reason?
What is missing on the PC?

earlier it worked fine on the same PC.

ART Tester Version: 2.45.0.2
ETS Firmware-Version: 2.44.4.2


Hello,
unfortunately the debug.log is only generated from a lib used in ART and does not really help here.

Hi Profinet Experts,
I am currently testing a PROFINET device using the Embedded Test System (ETS) and Automated Real-Time Tester (ART), and I ran into an issue that I am hoping to get some insights on.

The device setup includes standard PROFINET configurations, and I am specifically running the ...

Excuse me, seniors, I would like to ask for your advice. In the 2024-07-30_PN-Test_V2450 Test Bundle, when using the Automated RT Tester software, the test item Behavior_-Scenario_10(CLRPC) failed, but the reason for the failure is unclear. The DUT (Device Under Test) provided a get-response, and ...

When I use the balenaEtcher to flap, I almost always get an error message that the verification did not work, is that ok?


The process should end with a successful validation. If you have this problem, please try common problem solutions. Like download bundle again, reinstall tester and try with ...

Is there a CLI (command line interface) for automation integrated in the ART Tester? Can pass/fail results be sent to another test framework?


Yes, we provide an AutomatedRtTesterCli.exe.
We do not provide a pass/fail in the output. To get a result please use the xml report that is provided for ...

Webinar_Question wrote: ↑09 Sep 2024, 09:56 Is it possible to test the CDML for controllers with the GSD Checker?

There is no Checker for CDML available, as the CDML is only used in the certification test and not like the GSD files in the engineering tools.

Webinar_Question wrote: ↑09 Sep 2024, 09:55 Does the ETS board support DCP DeviceRole=0x03 in new firmware?

The ART supports devices that send DeviceRole as 0x03.
But please note, that ART does only test the device or the controller part. Not a combination.

Webinar_Question wrote: ↑09 Sep 2024, 09:54 Is there any dll available for automated PROFINET testing without using ART software?

Every Testcases is provided in a separate dll file, but these files use the API of the ART base implementation. There are no standalone dll files for testing.

Webinar_Question wrote: ↑09 Sep 2024, 09:45 Is there a tracker for bugs?

Yes, there is a bug tracker. Access can be requested via PNO office.

What is your recommendation to have more than one Version of ART installed?


It is not recommended to install more than one version of ART. A parallel installation is prepared if this is intended. Like for Innovation bundles.

There can be multiple versions of ART on one PC, if the installation ...

Webinar_Question wrote: ↑09 Sep 2024, 09:44 What do I have to consider when testing the ART of a 1-port device with regard to the MAC and the settings? How about port MAC same with interface MAC?

That is no problem. Port and interface MAC have to be set, it is no problem if they are the same.

If the controller tests with the ETS no longer require TFPC, what is used instead to exchange the necessary information between ART Tester and DUT? What changes are required for already implemented controller tests that are based on TFPC as stated?


There is no substitution of TFPC. With ...

Webinar_Question wrote: ↑09 Sep 2024, 09:40 What is meant by 'automated comparison of test results' with respect to the CLI in ART?

The CLI of ART is capable of doing some basic comparison between two projects.

Is a special PC network card needed for running the certification tests based on ETS?


For official certification a specific PC with specific network card is defined to ensure reproducible results.

For in-house testing even other network cards might work but in case of issues, the specified ...

I followed the guide on how to create a custom power outlet for the Automated RT Tester .
Unfortunately, the DLL that is created by Visual Studio can not be loaded by Automated RT Tester .
It fails with the following error:

I think I do not understand your question? Can you be more precise what you want to do?
Because for PROFINET, you need a profinet controller.

Hello PROFINET Forum experts.

I tested our device with ART(2.44.1.2). The device has 16 electrical ports and 4 optical ports.
I meet a strange problem when testing Different Access Ways Port2Port (CLRPC).
The failure information of the case is shown in the attachment.

Hello.
We have written our own Power Outlet DLL for our test environment. Base was the template which is part of each ART Tester version.
Switching dut on/off/toggle works fine. But the ART Tester does not wait (e.g. the configured DutBootUpTime / DcpResetToFactoryTestSetupTime / ...) after ...
