Tag Logging on Datachange.

Hi

I need to log when a product type is changed. 

So I would like to log this Tag on a data change. 

How is this possible? I only find cyclic logging in Tag Logging.  

Hello,

what version are you using? In wincc 8.0 the after every change option appears

Thanks you

HI 

I am using 7.5 SP2

Havillant Comet, could you take a screenshot of where you can choose "Every change". 

Maybe I am not looking at the right options. 

Ohh... I found it! Thanks! 

Hi again. 

As I understand it, Auqusition type is how often the tag value is updated from the PLC.
When I set Auqusition type to 'After every change' the Auqusition type will default be 500ms. 

But Archiving/display cycle is still cyclic. eg.  5sec. with a factor. 

So how can I set Archiving to execute only when data value changes?

I would like to have a WinCC OnlineTabelControl that shows a row for every data value change, not cyclic. 

Ok, I found that setting Acquisition Type to 'After every change' and Archiving/display cycle to '1 day', 

the display cycle will be 1 day, but a value change will also be displayed. 

So this way I can have a table only showing value changes.
