Monitoring temperature with WinCC flexible

vince1980 Posts: 6 Rating: (0)	Hello, About Monitoring temperature (HVAC), Is that possible for an operator (or other level) to change configuration settings with WINCC flexible in order to record temperature every 15 minutes and not every 15 secondes as currently defined? Too much temperatures values are displayed on the charts..... Thank you so much Regards Vincent

The trigger of this function can you create with your PLC. Trigger_1 ---> 15 secondes Trigger_2----> 15 minutes How are tags and alarms logged in WinCC flexible? Tweety

vince1980 Posts: 6 Rating: (0)	Hello Thanks for your feedback! I'm not sure but I think that there is no "on demand" available for final user. I think that It's configured like this (by default) The values displayed on the charts are those which where recorded every 15 seconds. This induces less visibility at least...for charts. Too much values Is it possible that is only one value to modify/replace in the operator's window configuration? If yes, could you upload a screenshot? I have difficulties to identify clearly the related window of the Siemens software (Step 7 or maybe Win CC flexible...) to perform directly such a change. Maybe Wincc flexible could allow this change with upper level? (supervisor or another...?) ...in all cases without specific programmation skills/access to another tool required? If this modification depend on programmation...please let me know (I’m not sure as you speak about “trigger”) Regards Vincent
