What happens when you specify and apply PI variables configuration to a project?

AVEVA™ Production Management does the following:

• Creates a PiVariable item to represent each variable that you selected to add. Where possible, AVEVA Production Management gives the PiVariable item the same name and a compatible data type as the corresponding variable on the PI server.

• Converts any special characters of the source variable name, including the dot character (.) to underscores to create the value of the Name property of the PiVariable item. This conversion occurs because the Microsoft .Net Framework uses the dot character as an object separator. However, for the PiItemID property, AVEVA Production Management uses the source variable name without conversion of special characters so that the server can still map to the correct variable tag on the PI server.

• Places the newly created PiVariable items in the PiGroup item.

• Deletes PiVariable items from a PiGroup item according to the variable check boxes that you cleared in the PI variable configuration window.

• Applies the variable mapping to the list of variables in the PI variable configuration window.
