Library Generator
FOREWORD
The purpose of this functionality is to provide, to firmware developers, the necessary tool to declare IEC blocks, including embedded ones, to be distributed as PLCLIB libraries.
Availability
The library generator feature is available on LogicLab BETA releases starting from 5.7.x.
GENERAL INFORMATION
Prerequisites
Library generation requires a ".plcprj" project with custom workspace option enabled ("Project" + "Options" + "General" + "Use customizable workspace").
Library generator folders
To mark a workspace folder as library generator, check the specific voice on the context menu (Right click on folder then "Edit folder properties").
Once done, a special icon appears to mark the folder.
Options
You can define some library options by editing those folder properties.
| Option | Description |
|---|---|
| Enabled | mark selected folder as library generator. |
| Version | Must be in X.Y.Z format (empty corresponds to default 1.0.0) |
| Password for encryption | Password used to crypt library content. |
| Crypt all contents | Library contents will be encrypted using the password above. |
Encrypted POUs
As mentioned above you can crypt all POUs contained in the library.Otherwise you can select individually each POU that has to be encrypted.
Check "Crypt with password" option on the POU edit properties dialog (Right click on the POU then "Edit POU properties").
The POU will be encrypted using the password given for the parent container folder.
Hidden POUs
POUs can be included as hidden on the generated library. Check "Generate as hidden" option on the POU edit properties dialog (Right click on the POU then "Edit POU properties").
Embedded blocks
Embedded blocks can be declared only in Library generator folders and its subfolders. Those special blocks don't contain any IEC code but only I/O variables declarations.
Make libraries
To trigger the libraries generation select "Generate library" on selected folder or "Generate libraries" of project root.
All libraries are created, in .PLCLIB format, on the PRJPATH/AutoGenerated libraries folder.
Header files
WORK IN PROGRESS
A more useful and user friendly method to customize the generated header files is under development.
