REX640 Engineering Manual

Data attribute mapping means that each FPN data attribute in the FPN model is mapped to a corresponding data attribute in the internal PCM600 model, that is, the real device in the substation.

The mapping status is indicated visually. It can be seen what FPN data attribute is mapped to what PCM600 internal data attribute and how many FPN data attributes are mapped to a PCM600 internal data attribute.

Data attribute mapping is complete when all data attributes of the FPN IED, which are not excluded from the mappings, are mapped to a PCM600 internal data attribute. Data attribute mapping must be complete to be able to write to IED.

Data attribute mapping is broken if any of the mapped data attributes - FPN or PCM600 internal - does not exist in the SCL database.

Note: All data attributes in the FPN model must be mapped or excluded, otherwise write to IED fails.
