XML Document Type Definitions (DTDs)

DataType.dtd

LibraryElement.dtd

FBMGT.dtd

• Missing x,y parameters have been added to AdapterDeclaration.
• Algorithms now have the possibility to have VarDeclarations of temporary variables.
• Applications now contain SubAppNetworks instead of FBNetworks.
• It is now possible to declare (network) SegmentTypes.
• An optional CompilerInfo sub-element has been added to the System element.
• CDATA sections may now be used to represent the text of algorithms in ST and Other languages, and the Expression portion of LD Rung elements.

2010-09-28: A Parameter element has been added to FBMGT.dtd for use in READ/WRITE operations, in anticipation of the corresponding change in the 2nd Edition of IEC 61499-1.

• RESET has been added to the list of enumerated values for the Request.Action attribute. This action is present in Figure 24 of IEC 61499-1, but was missing in Table 8 (this will be corrected in the next Edition of 61499-1).
• The list of enumerated values of the FBStatus.Status attribute has been changed from (INITIALIZED|WAITING|EVALUATING|PROCESSING|STOPPED|KILLED) to (IDLE|RUNNING|STOPPED|KILLED) for consistency with Figure 24 of IEC 61499-1 The previous list was from a very early Industry Technical Agreement (ITA) and was rarely if ever implemented.

2009-03-07: LibraryElement.dtd has been updated to correct an error in the definition of the Application element. XML files of IEC 61499 system configurations produced by previous versions of the FBDK prior to this update may not comply with these DTDs. The XMLChecker application can be used to check for this compliance.
