Hello Vippi

I´m Sorry but there is no such System Taga or something else.There is also no Logging Object in VBS Object model. you only can try to set your own Tag if you start and Stop the logging.

Hello Vippi

yes I know its not a smart solution. but if you stop the runtime then the loggin will also stopped. and if you start the Runtime often (you can set in the TIA Project) the logging is started automatically.

So if you use an internal HMI Tag you can set it in case of Runtime Start to 1 then you are consistent again.

And you can use also the Event Runtime Stopp in the Scheduled Task editor. Then you can also know when the Runtime and the Logging is stopped
