Since yesterday I started to get these errors.

Seem to happen when one of my C# blocks is writing files. But I haven't changed that code taht has been working for months already.

What does it mean? 

 

Using PLCNextEngineer 2020.6 and Firmware on PLC is aslo 2020.6

Hello alexsanchez

the message is independent of the C # FBs and has no effect on the function of the controller in terms of real-time and process data. There could only be problems with the neighborhood detection (Profinet features). 

It would be interesting to know exactly how long the problem started. A log file would be helpful.

Possible causes are:

Full SD card
Internal / external SD card problem
Changed permissions

For uploading the logfile data to the ShareFile server, please use the following server link:

Thank you Eduard,

 

I have uploaded the Output.log

The last time I saw that error was at:

11.11.20 10:37:38.278

 

Keep in mind that one point the PLC did not have the SD card (can't remember exactly when we installed it) but even after that, we got the error.

Please let me know your findings,

 

Alex

Hello Alex,

I do not found the cause of Error Message in Output.log file, but I can try to reproduce it, if you send me your C# project.

Please send me also the PLCnEng project, if possible.

Hi Edward,

 

Before sending our project we were doing some testing and found out that using the Garbage Collect Method helped us.

 

https://docs.microsoft.com/en-us/dotnet/api/system.gc.collect?view=net-5.0

 

I haven't got the error anymore, but will continue testing.

 

Thanks,

 

Alex
