Interface PItoPI & Location 4

Hi all,

 

I'm tryng to configure a tag on an interface PItoPI, with scanclass 1 (event scanclass), so that when the tag on PI source change her value, at the same time, this value is reported on tag PItoPI; but I see an issue with this behavior. In the archive of the PItoPI tag, I can't find the last current value(snapshot) present on PI Source, but it is always one value back.

 

For ex, with PI SMT, in archive I can found:

 

tagPITOPI, x value at 06:05:00

 

tagPITOPI, y value at 06:07:00

 

tagPITOPI, z value at 06:09:00

 

-------------------------------------

 

tagPISource, x value at 06:05:00

 

tagPISource, y value at 06:07:00

 

tagPISource, z value at 06:09:00

 

tagPISource, w value at 06:11:00

 


 

... the current value for tagPITOPI is z at 06:09:00, for tagPISource is w at 06:11:00

 

When a new value arrive for tagPISource, on archive of tagPITOPI I can find w value at 06:11:00.

 


 

What could be the cause? In the tag's configuration or interface's configuration?

 

Best Regards,

 

Marco
