CIM Issues » WG13 Issues

Problems found in the latest draft of the template for IEC 61970-453 for CIM 18:

Contains one or more references to IEC 61970-451. The referenced document does not exist and this reference should be removed.

Contains references to the specific contents of the IEC 61970-552 header. This description will no longer be valid in IEC 61970-552 edition 3 and should be removed or rephrased in a less specific manner.

Constraint C:453:DL:Diagram:units makes an unverifiable restriction of requiring units to be in millimeters. This is unverifiable. If I put in a value of "40" how can you prove that it is or is not millimeters?
Are we requiring screen DPI to be taken into account? Should it be 40 mm with a ruler held up to the operator screen? should be also be only 40mm on a ruler held up to the mapboard wall? Is zooming in and out forbidden because it would change the physical distance?

Constraints C:453:DL:DiagramObject:SynchronousMachine and C:452:DL_DiagramObject:PowerElectronicsConnection assume that the only types of diagrams that can exist are network diagrams. The prohibition of GeneratingUnits means that is impossible to create an AGC display or a production overview display or a facility display.

Constraint C:453:DL:DiagramStyle:name assumes that the only types of diagrams that can exist are network diagrams. What about SCADA diagrams? What about AGC diagrams? What about overview diagrams? What about simplified diagrams?
