Thank you for your reply.
Your topic is not - derailing topic. I make standard and cheap automaton systems, my clients want cheap solutions.
I see like same you. The normal mode is 1 minute and 4seconds. In auto tune I do not calculate. But I think the method is from time duration devided the sum ofabcissa units.Is this correct?
Sorry for derailing topic.
I tried playing with it. When monitoring 1 unit is 1 minute and 2-3 seconds. When running autotune 1 unit is about 30ms. It doesn't seem consistent, it is the same if you change sample time. Maybe it depends on communication with controller.
If you need time values to analyze your system I suggest calculating it manually by dividing your total online time with displayed units under the graph. Maybe someone who knows better can chime in, but I don't see any more settings for time axis.
I can remember a time in the "way-back", when I had set up a control for a small machine. just a PLC with switches and lamps for the User Interface,
then they decided they needed to be able to adjust the time of a certain function, so I added some small red lion display that showed the timer preset with up/down buttons to change the value. For some reason I couldn't define the decimal position on the display, and the operator was confused by the term Implied Decimal. I'd point to the spot and say "just pretend there is a decimal point here", he still didn't get it...
Finally, I grabbed a bottle of White-Out, and made a "dot" on the display.... Oh, now I get it....
