Hi, I have a problem. I get data from http get request in JSON format. When I use http_sys.hTTPClient_0.httpResult.wsContent (WSTRING) everything with chars (UTF-8) is ok. But for the needs JSON Parse I must use http_sys.hTTPClient_0.httpResult.sContent (STRING) data and in this case I have problem with Polish characters. After parse I create variables to print on HMI(webvisu): description:= STRING_TO_WSTRING(NewJSONObj.description.AsString); And the result is that I have no Polish characters. How...

I'm still working on this, but if you use the code here https://forge.codesys.com/forge/talk/Engineering/thread/1f8eee253c/ I'm using a struct to store all my different variables and then using the pointer to the struct memory location and then setting the data length greater than what is in the struct. My plan is to modify the FB so it automatically reads the length of the data and so you can assign the struct directly to it. Have not had time to do this yet. Your next issue will be the SD card...

I think I have it sorted now... looks like something may have gone wrong with the upgrade. I removed everything with sudo dpkg -r codesyscontrol and then reinstalled via codesys and everything seems to be working as it should now. So during the package upgrade from 4.1.0.0 to 4.2.0.0 something must have gone wrong or not installed correctly.

Hi, I have attached the PLC Log after a reboot Note: I had to start runtime using " sudo service codesyscontrol start " No the system is not read only. Everything was working fine and then upgraded to v3.5.17.30 and that's when the auto start stopped working.
