EtherCAT.NET

EtherCAT.NET copied to clipboard

Hi, when building EtherCAT.NET-master with powerScript .\init_solution.ps1 the process ended with error. It says: „... does not contain a CMAkeLists.txt file“ Obiously there is no such file in the folder ...\native\SOEM. Consequently no soem_wrapper.dll is being built.

I am using VS2019, powerscript 7.x, net core 3.1 etc. How can I solve the issue. Regards

What happens if you make a clean git clone and then run the script? What is the console output?

Well, I downloaded the code as .zip and opened it with 7z. First thing when run in PS is: term ‘git’ is not recognized. I have no clue why this happens! Second issue is as described above; no CMakeLists.txt where found in the ./../native/ SOEM.

Maybe anything wrong with PS settings?

Sorry I presumed you are using git to clone the reposity. Downloading the .zip and extracting it should make no difference.

Do you have Visual Studio with the C++ workload installed? Thiss workload provides the C++ compiler required for cmake.

The easiest for me to find the reason would be if you take a clean copy of EtherCAT.NET, run the powershell script and post the full output here.

Here is the expeced output:

Hi, thanks for advice. After reinstalling the git and adjusting the environmental var’s it finally worked. I can see the dll’s for the wrapper. However, they are not created when running the EtherCAT.net.sln in the VS2019 IDE. I keep struggling Best wishes

The native DLLs are not created when compiling the managed DLLs (EtherCAT.NET.sln). They can be compiled using msbuild:

msbuild ./artifacts/bin32/SOEM_wrapper/soem_wrapper.vcxproj /p:Configuration=Release
msbuild ./artifacts/bin64/SOEM_wrapper/soem_wrapper.vcxproj /p:Configuration=Release

I have no test setup right now, but somewhere in the artifacs/bin32 or bin64 folder, there should be another .sln file which can generate the native DLLs.

Hi, meanwhile the code compiles fine without error and can run. But, excecution failed at EcUtilities here: EcUtilities.CheckErrorCode(context, EcHL.ScanDevices(context, interfaceName, out var slaveIdentifications, out var slaveCount)); error 0x104, did not reach PreOp-State.

I can run slaveinfo.exe on same system with success. Anything overlooked?

Are you able to read out the slave state, right after catching the exception?

Maybe calling Ecutilities.GetSlaveStateDescription(IntPtr context, IEnumerable<SlaveInfo> slaves) helps to find the reason for the slave not getting into the PreOp-State.

var master = xxxx;
vat statusDescription = Ecutilities.GetSlaveStateDescription(master.Context, slaves);

Console.WriteLine(statusDescription);

The important part of the resulting string is the 'AL-Status' which can be translated here or here.

I get no slaveinfo yet. The system collapses before retrieving the slaves so as the status code. The output on exception is: An unhandled exception of type 'System.Exception' occurred in System.Private.CoreLib.dll ScanDevices failed (0x0104): One or more terminals did not reach PreOp-state. hm!
