Project Information

Rule #3:

Fill in the Project Information (Required)

This data is important for switching off the CODESYS default behaviour.

It is also important for a self-describing library.
Activate namespaces.
Define the library type
Do not select "Automatically generate 'Project Information' POUs"

Please do not check "Automatically generate 'Project Information' POUs"!

Note

The option "Automatically generate 'Project Information' POUs" results in huge memory footprint and require WSTRING support. WSTRING support is not optimal for PLC controllers with a small footprint. In the past, this option was useful for having a simple way to get the version and the release status of a project.

With CODESYS V3.5 SP8 (CDS-27155) are now a new set of functions called 'Library Information' available, consisting of three functions:

GetLibVersion: VERSION
GetLibVersionNumber: DWORD
IsLibReleased: BOOL

Please check "Automatically generate 'Library Information' POUs".
