CSharpExamples - FB_with_user_struct2 - PLC los connection to PnE

rintaro · November 28, 2019, 1:31pm

Hello community, I tried one of the C# examples.

So far every example has worked. Only with the example “FB_with_user_struct2” my CPU seems to lose the connection to the PnE. https://github.com/PLCnext/CSharpExamples/blob/master/PLCnext_CSharpExamples/03_UserStruct/FBWithUserStruct.cs
In Visual Studio the examples can be built without problems.
In PnE I can also integrate the block into the project without errors. After transferring the project the PLC lose the connection. I have to delete the project via WinSCP (/opt/plcnext/projects/PCWE/Plc/Eclr/eCLR.img) to be able to reach the PLC again after a restart. Does anyone have any idea why? I use PnE 2019.9 and the PLC AXC F 2152 with Firmware 2019.9 and Hardware 02. Thanks

Hello rintaro, I can reproduce this behavoir. Please find on GitLab the updated example program. Please note, currently it is possibe to use the Pointer only for Input and InOut parameters! https://github.com/PLCnext/CSharpExamples/blob/master/PLCnext_CSharpExamples/03_UserStruct/FBWithUserStruct.cs Best Regards Eduard
