GF Posts: 17 Rating: (0)	Is it possilbe to copy the values from one curves to another during set-up? I want to trend 8 Temperatures with the same properties on the same pdl. and would like to set-up a single curve then copy to another curve and select another tag that will have the same parameters. Thanks.

When you add a new curve to a trend it picks up all the default settings. However ... if you are familiar with VBA you could write a function that automatically set the properties for new curves. The key is to look at the Properties Dialog box and not the Configuration Dialog Box. As Danielle mentions, setting the Index property sets all other properties to reference that curve. So if you set the Index to 0 then all properties are looking at your first curve. If you set the Index to 1 then all properties are referencing your second curve. You could write a VBA function that automatically copies the properties of the first curve and pastes it onto all subsequent curves. I would like to stress that this is not a standard function and you would have to write it yourself. Unless anyone else has already done this ?

I was referring to VBA which will make the change on the PDL in the Graphics Designer. GF, maybe you should do it in Runtime and ask Danielle for their script ?

Danielle Posts: 1275 Rating: (123)	I didn't send the script 'cause it's quite long, and all the tags and comments are in Portuguese, and you kinda need those to configure... [:(] And I'm currently caught up in an iFIX project, so I don't have time to translate it and post it... [:(] Unless you're interested in learning some portuguese... [:D] Setting the index goes somewhat like this: SetPropWord(Screen_Name, "Trend_Control", "Index", 0); // Screen name was supplied as a parameter when calling the script, "Trend_Control" is the Trend control object's name... Of course you'd have to set all the trend propertiesmsuch as "RelayCurves", "GridLineValue" and so on... Sorry I couldn't do the whole script! [:(]

That was not my intention [:blush:] Thanks for the extra info though. I think this faq will help with examples too for GF http://support.automation.siemens.com/WW/view/en/23416667
