PI AF structure for OpenPCS 7 data

In the figure below there is an example of an OpenPCS 7 followed by a screenshot showing the result in PI AF.

OpenPCS 7 example

In PI AF, the connector replicates the OpenPCS 7 process groups to PI AF elements and the OpenPCS 7 variables to static and dynamic PI AF attributes. The SIMATIC S7 Protocol Suite object was considered an entry to the OpenPCS 7 hierarchy.

OpenPCS 7 PI AF hierarchy

Here is an example of individual element names in the PI AF hierarchy:

Pcs7Demo\Distillation\FIC_Feed\PID

These were derived from the individual element names, as in:

• Pcs7Demo: The Data source name, specified in the connector's configuration page.

• Distillation: The value of the OpenPCS 7 variable #areaname.

• FIC_Feed\PID: The OpenPCS 7 process group.
