Process Control and Statistics

rjduraocosta Posts: 14 Rating: (2)	Hello, I am using Wincc 7.0, and i am looking for a way to control processes so that i can afterwards do some statistics with these stored values. I need to monitor tags in a daily, monthly and early basis so that i can know for how long the Tag had a certain value, in absolute andpercentage values,since the system started, in a specific time frame. Is there any way to do this in wincc 7.0 directly, i mean without any options package? I have been looking for this answer for a long time, but i have not reached a conclusion. Help please!!!!!!!!! Thanks in advance.

TimeRange) by a button-script. So you have one Control and a lot of buttons, where you can show what you need. Add to the Trend Control a WiinCC Ruler control. an you can calculate a lot of values. regards cumulus

rjduraocosta Posts: 14 Rating: (2)	Thank you for your reply cumulus,I have already tried what you mentioned, but i don't think it can do all the statistics that i need. For instance i would like to define a especific calculation for an archived value is that possible? I want to monitor a escific bit, then i would like to show for how much time in a especific time frame that bit had the value "1" or "0", so that i can then calculate the amount of time it was "1", or "0" in percentage? Is this possible?Thank you in advance
