Hello.

WinCC Professional V14 SP1

I have a screen called "TrendScreen" that consists of Online Trend Control & Trend Ruler Control, I want to call this screen more than 200 times since I have a power switches with trends for  "Amp, voltage, PF".

the available solutions i think:

1- use a screen Window with Tag Prefix, the disadvantage is a high number of screen windows. since each switch needs a screen window

2- at the main screen for each power substation which contains many switches, I can put the two objects (Online Trend Control & Trend Ruler Control) with invisible mode and at each button I can pass the trends tags "Historical" to the Online Trend Control using VB script and make the two objects visible.

3- Can i call the screen window using VB scripts in each button and pass the Tags to the Online Trend Control at runtime?

i'm looking for a less effort solution, if you can advise me for the best solution?

thanks

Yes. Change .txt to .pdl

Check this one with WinCC 7.3 or 7.4

I dont have Wincc v14 prof since i've wincc 7.4. otherwise i'll check that too.

In this I did script to change the tag in runtime. Try like this in V14

thank you, but I can't open the file with .pdl, can you save the code with pdf format?

thank you.

I have already done this without any problem.

my question was:

I have a screen called "TrendScreen" that consists of Online Trend Control & Trend Ruler Control, I want to call this screen more than 200 or 300 times inside my project.

For example substation or location  A with 20 switchgears, and for each switchgear there is a trend for ampere, ampere,  voltage, power factor.

Now I have more than 30 substations, so imagine the huge number of screen windows if I use a screen window with Tag Prefix!

so the best way is insert a screen window with displayed screen "TrendScreen" in each substation different screen, can I pass these tags into an Online Trend Control inside a screen TrendScreen inside a screen window without using Tag Prefix?

Or in each substation screen I should add an Online Trend Control and also Trend Ruler Control without a screen windows and make there visibility is false and at the button pass the trends tags and make them visible?

thanks
