199 Input of logical nodesCreated: 05 Sep 2005 Status: In Force (green) Part: Part 7-4 (2003) Links: Page: Clause: Paragraph: Category: Issue for edition 2 of this part Issue Once again, the issue of the logical nodes' inputs has been raised during a work shop. Inputs of logical nodes can be defined in the SCL, but are not visible over the communication. The importance of self description of an IED over the communication channel requires a solution. Proposal Propsal: add a generic input (optional) in the common logical node definition. This generic input can be instanciated as often as required, and needs a new CDC. This CDC contains (at least) 2 attributes: ExtRef and IntAddr (as it does in the SCL). The ExtRef is similar to the definition of setVal of ORG (the CDC we use for Historical and Statistical Data and for the Logical Node grouping) : reference of the Data Object that will be required by the LN. The IntAddr is a VISIBLE-STRING and contains optionally a manufacturer specific internal address (this onee could be aded in the PIXIT for engineering purpose for instance.).
