In the PmaData object, the #vars identifier is used to enable variables (of the PmVar type) defined on the "Data" page. This identifier can be used e.g. for the Pm method, or for the PP data binding in the application and in panels. For example the method Pm("data1/#vars/aaa") returns the data item aaa from the object named "data1" of the PmaData type.
References to Data extensions objects in the PmVar variable can also be done directly by extending the path of the Pm method using the #ext identifier. This can be used in the Pm method or in PP binding in the application and in panels. For example the method pMe.Pm("/data/#vars/Temperature/#ext/al") returns the data extension with al identifier (ExtAlarmAnalog) in the "Temperature" variable (PmVar) in the "data" object (PmaData).
