Unleash the Power of LogicLab: A Comprehensive Guide to lltool

Tired of wrestling with LogicLab files? Want to streamline your PLC project development? lltool is your answer. This powerful command-line tool simplifies the manipulation of LogicLab files, offering efficient conversion and updating capabilities. This guide dives deep into how to maximize lltool's potential, boosting your productivity and ensuring error-free PLC projects.

What is lltool? A Swiss Army Knife for LogicLab Files

lltool is a command-line utility designed to convert and update LogicLab files with maximum efficiency. By minimizing dynamic memory allocation, lltool ensures swift operations. It handles:

• Conversion: Transforming LogicLab libraries between different formats (.h, .pll, .plclib).
• Updating: Seamlessly updating libraries within your LogicLab projects (.ppjs, .plcprj).

Key Benefits: Why Use lltool?

• Efficiency: Designed for speed and minimal resource consumption.
• Automation: Perfect for integrating into automated build processes.
• Command-Line Simplicity: Easy to use with clear, concise commands.

Getting Started: Installation and Requirements

Before diving in, ensure you have the necessary prerequisites:

On Windows:

• C++ runtime: VC_redist.x64.exe.
• Notepad++ for parsing error display.

On Linux:

• mousepad for parsing error display.

Core Functionality: Converting LogicLab Libraries

The convert task is the heart of lltool. It allows you to translate between different LogicLab file formats, enabling compatibility across various versions and systems.

Supported Conversions:

• .h (Sipro header) to .pll (Plc LogicLab3 Library) and .plclib (LogicLab5 PLC LIBrary)
• .pll to .plclib

Pro Tip: The file extension dictates the conversion process.

Example: Converting Multiple Files at Once

$ lltool convert prog/*.h plc/*.pll --options timestamp,plclib-indent:3 --force --to plc/LogicLab/generated-libs

This command converts all .h files in the prog/ directory and all .pll files in the plc/ directory. The output will be placed in the plc/LogicLab/generated-libs folder.

Conversion Options: Tailoring the Output

Fine-tune your conversions using comma-separated key-value pairs with the --options switch.

Example Options:

• plclib-schemaver:2.8: Specifies the schema version for .plclib files.
• plclib-indent:3: Sets the indentation level for .plclib files.
• timestamp: Adds a timestamp to the output files.
• sort: Sorts the elements within the output file.

Core Functionality: Update LogicLab Projects with Ease

The update task streamlines the process of updating your LogicLab projects with the latest library versions. It identifies external linked libraries and refreshes their content within your project file.

Example: Updating a LogicLab Project

$ lltool update "C:\path\to\project.ppjs" --force --to "C:\path\to\project-new.ppjs"

This command updates the project.ppjs file, saving the modified version as project-new.ppjs. The --force switch ensures that the output file is overwritten if it already exists.

Actionable Tips and Tricks

• Utilize glob patterns (e.g., *.h, *.pll) to process multiple files simultaneously.
• Always back up your original project files before running the update task.
• Take advantage of the --force switch to overwrite existing files when needed.

Common Pitfalls and How to Avoid Them

• Encoding Issues: Ensure your input files are encoded in UTF-8 with Unix line breaks (\n) to prevent parsing errors.
• Case Sensitivity: Be mindful of case sensitivity, especially in file extensions and within .pll files (keywords must be uppercase).
• Syntax Limitations: Adhere to the specific syntax rules for .h and .pll files to avoid parsing failures.

Automating Your Build Process: A PowerShell Script Example

The following PowerShell script demonstrates how to integrate lltool into a complete build process:

# [Generate libraries]
& lltool convert PROG/*.h PLC/*.pll --options plclib-indent:3 --force --to $libsoutdir
check_exit_code "lltool convert" $LASTEXITCODE

# [Compile project]
$ppjs_compiled = compile_plc_project $ppjs
