I have tried to display historical data to trend view following that confusing document, with no success.

https://support.industry.siemens.com/cs/ww/en/view/109477071

Historical data logging Works as expected, I have the saved values, I can check it by Excel-CSV, etc.

So cited document does not attach full WinCE script, and sample project give me errors while trying to open even with TIA V15_SP1 trial software (I’m still using TIA V14 with S7-1500 and 9” comfort panel) and just this maybe can solve my doubs.

Problems I'm facing seems me that are coming from file management, and VB Scriptint limitiations under WinCE.

Thank you in advance

Hello McAndrew,

I looked into the "SIMATIC WinCC WinCC Engineering V15.1 - Programming reference" :

And there is no "Attributes" property listed, just an "Attr" property which is read-only:

There is a "SetAttr" method, I recommend to try this out to set attributes:

Hopefully this is helpful.

Hi

Now, I have revised everything and I found an error at script. I was pretending to manipulate the file while still on use from other side. So the attributes was not apparently the problem.

So now I can have properly copied the file from long therm to actual trend.

The piti is that is still not showing any trend. I mean, now I copy properly the file, I do all the steps with no errors, I execute a "OpenAllLogs" and I set the trend time to some value contained into file. Connecting to screen with smartaccess and browsing logger all setps seems to be done properly, with no errors, but trend is still not displayed

If I set time after records trend table becomes blue, but when browsing values contained into log, returned values are ### or 0,000. At trend nothing is displayed.

Any idea on what else to look for?

Found the problem with support, and it is not the file copy.

The story is that after copigin the file, variables names into the file must be edited to align to project.

I mean. Variables can not be duplicated, so 2 historical records are done, one for logging, and one for displaying. So after copying file, editing the variable name, will show trends stored.

Fins attached the script done to do so. On that way by means of SD card, its is amazing what a simple comfort panell can do.

Hope can help someone
