A bit of work but maybe possible to make your own driver using "CODESYS Control SL Extension Package". Look at the "ExternalIoDrv" example. It is installed in "C:\Program Files\CODESYS 3.5.20.0\CODESYS\CODESYS Control SL Extension Package" when you install the "CODESYS Control for Linux SL".
Just adding: sSubscriberdata := ''; Right before your memcopy should fix the extra characters. It is because your are copying 36 characters into a string which can contain more than 36 characters and there is garbage left in the extra characters.

Same problem here. I am pretty sure I was able to make it work a couple weeks ago but now I cannot make it work anymore. Always get FILE_OPEN_ERROR
Yes it is possible. I did it a lot of times using TeamViewer VPN. Unfortunately, TeamViewer VPN only works on Windows. If the remote PLC is a Codesys runtime running on Windows, you should be able to login directly using TeamViewer VPN if it is installed on the PC/PLC. If it is not Windows based, you can still do it but you need to have a Windows based PC acting as a gateway in the middle. In this case you need to enable IP Forwarding on the Windows remote PC (the gateway) and you need to setup the...
