Hello , perhaps a min/max-calculation will be solved fasterin PLC and not in WinCC. Use two PLC variables which are updated accordingly in PLC. Georg |

Hello mvisconte, AutoRange is setting the valueaxis according the incomming values, therefore you
should set it to "No". Then it works similar as in FAQ http://support.automation.siemens.com/WW/view/en/11942662 for the timeaxis. At first you have to set the property "ValueAxisIndex" to "0" for the first valueaxis, then write the properties "ValueAxisBeginValue" and "ValueAxisEndValue". Then set the property "ValueAxisIndex" to "1" for thesecond valueaxis, then write the properties "ValueAxisBeginValue" and "ValueAxisEndValue". a.s.o. Regards Georg Berghof |

I wish it was this simple, but unfortunately it is not. It keeps reading the last user-supplied values, regardless of the auto-range values :(

Unfortunately these properties are only available with Online Trend control, and I use a function trend control. Thank you very much for your help.
