Split from WinCC advanced High frequency data logging.

Hello mmmehdimohamad

the fastest logging cacle for a cylic logging ist 1s in WinCC Comfort/Advanced.

you can try to set to "on demand" and use a Trigger Tag with 100ms cycle and cyyclic continious reading in the PLc to a toggling tag and the systemfunction to log the value. But I would not recommend this very often. this will stress your sysem and of course its not guaranteed that it runs in 100ms cycle

you can also use an array in the db to buffer the tag values and timestamps. with a Script you can read the values and write it every let´s say 10 seconds and look if it works...

but anyway... this System is not made for faster logging that 1s in general
