Company

Title

Version

 Defines the SFC library that CODESYS uses by default.
Namespace Enables unique references to libraries. Required when various versions of the library are available on the system. Please make sure that there are no discrepancies between the namespace defined in the library manager and the namespace defined for the individual object. The SfcIec.library data is used for the default settings that CODESYS provides with the default profile.

Note

Each SFC block stores the information via the library version that applied when you added the block. This can cause you to use multiple library versions within the same project. In order to prevent this, you are prevented from defining specific versions of IecSfc.library (as of compiler version V3.4.1.0). The library version, which you use for all SFC blocks in the project, is defined with a placeholder. CODESYS resolves the placeholder depending on the compiler version in use. The allocation of the library version to the compiler version is defined in the library profile.
