Hi, I have a AS project written in V3 and want to convert it to V4 I have done this before, but this one has a X20SL8001 safety PLC running safety release 1.5 Is it possible to convert this to AS4? I can’t find any safety releases under AS4 which will work Thanks, Brian

Thanks Pavel, looks like none of the safe designer versions work with Windows 11, so it’s a non-starter All the best, Brian

Upgrade AS3 to AS4 with safety PLC

The only compatible combination for Windows 11 is SR 1.10 + SafeDESIGNER 4.4.1. See this topic.
