Library: Analyzation

This library contains POUs for the analysis of expressions. If a compound expression has the total value of FALSE, then those of its components which contribute to this result can be identified. In the SFC editor, the SFCErrorAnalyzation and SFCErrorAnalyzationTable flags implicitly use these functions to examine transition expressions. The flags then provide the identifiers of the variables which contributed to a timeout error. They retain this information until the SFC flag SFCQuitError is used to explicitly reset the information.

An analysis POU cannot be called via a pointer. This kind of request will be ignored. Call the POU as a single instance.

For a description of the library POUs and an example of how the SFC flags display the analysis results in CODESYS, see the documentation for the library in the online portal or directly in the Library Manager.
