Post by mtho on JSON Utilities - JSON file written with invalid structure ^{CODESYS Forge talk (Post)}
I'm using the JSON Utilities SL library to write configurations in my program to a file. I'm generating the JSON data using the builder function block and all appears to work correctly. When I write the jsondata to file, I'm finding that some of the JSON elements are not being written in the right location in the file. Rather than writing they keys under the parent object, they get written outside the root JSON object at the end of the file. If I then try to read the file back into the program, I get an invalid_structure error. I don't get any errors when populating the JSON data or when writing the file. I attached an example of the JSON writer output. The problems begin with key P200. Each P200 should go under MBR1 through MBR3. Among the rest of the keys, they are supposed to be under different parent objects. I am using default values for wsLineBreak and encoding.

Post by kuegerls on CSV Utility SL ^{CODESYS Forge talk (Post)}
Hello, I want to read a CSV file using the CSV Utility SL library, but I encounter an 'invalid_handle' error during initialization. What could be the cause? For my test program see the screenshot. I have purchased a license, and it is also installed on my PLC. Thank you in advance. Best regards, Stefan.

Post by transmin01 on PCAN serial "No CAN driver found" ^{CODESYS Forge talk (Post)}
Hi, I am using a PCAN mini CAN board which has the Windows drivers installed on the target PLC. PCAN board can be seen in device manager. However, I am getting "No CAN driver found" error. I have read the post https://forge.codesys.com/forge/talk/CODESYS-V2/thread/44aae19318/ and have uncommented the CmpPCANBasicDrv driver in the CodesysControl.cfg file in development PC and have copied it to the target PC. Current CodesysControl.cfg file attached. Is there anything else I am missing? Regards
