[C#] [ReportControlBlock] The methods (SetTrgOps / SetOptFlds) throwing System.AccessViolationException about libiec61850 HOT 5 CLOSED

I tried this with the 64 bit compiled native DLL and the examples I have for reporting ("reporting" and "report_new_dataset" and the problem doesn't show. Have you tried the examples? Do they also show the problem for you?
Maybe in your code the connection doesn't work and "self" is a NULL pointer?

Hi @mzillgith,

I found a way to work.

Call the methods: SetOptFlds and SetTrgOps
BEFORE the method GetRCBValues and the exception will not be thrown.

Probably, the method GetRCBValues must be blocking some memory access lock.

Hi @IgorMundstein ,
I have seen in your video that the RCB reference uses the "$" as separator, while the examples are using the "." as separator. In fact the GetReportControlBlock method assumes the "." signs in the reference and cannot detect if it is an buffered report when using the "$" signs. Because the GetRCBValues function later assumes it is an unbuffered RCB where the elements are slightly different the memory gets corrupted. When you are using "DemoProtCtrl/LLN0.BR.brcb02" as reference it should work.
I know it is a bit confusing that the "." signs have to be used for the RCB reference while the "$" for the data set reference in the RCB. I will change the code so it will accept both types of separators.

I did not realize it. I am used to remove FunctionalConstraint from address and replace $ to .

Like I do in the method "ReadValue", for example. However, it have the parameter (FunctionalConstraint ) in the signature.

Thanks!
