The purpose of this tutorial is to explain how to insert the Util library into a MasterTool X project.

Components

Equipment: 1 computer/laptop.

Software:  MasterTool X

2. DEVELOPMENT

1. ARCHITECTURE

A computer/laptop will be required to use MasterTool X.

2. DEVELOPMENT

During the development of a project in MasterTool IEC XE, it may be necessary to use features that are not available by default in the environment. For this, the software allows the addition of complementary libraries, which expand the project’s functionalities.

These libraries may contain:

• Additional functions
• Function blocks
• Operators
• Specific resources for certain applications

Proper use of libraries makes the project more complete, modular, and scalable.

Inserting libraries into the project

To add a new library to the project, follow the steps below:

1. In the project tree, locate the item Library Manager.
2. Right-click on it.
3. Select the option Add Library.

After this action, a window (popup) will open containing the libraries available in the environment.

Library selection

In the selection window, the user can locate the desired library in two ways:

Option 1 – Navigation through the structure:

1. Navigate to:
   Application → Common → Util
2. Select the desired library
3. Confirm the selection

Option 2 – Direct search:

1. Use the search field located at the top of the window
2. Type the name of the desired library (example: Util)
3. Select the library from the displayed list
4. Confirm the selection

After insertion

Once added:

• The library will appear listed inside the Library Manager
• Its resources will be available for use in the project
• It is not necessary to restart the software

Best practices

• Add only libraries that are truly necessary for the project
• Avoid excess libraries to prevent overloading the project
• Use reliable libraries compatible with the controller

Practical application

Adding libraries is used when the programmer needs to:

• Expand system functionalities
• Use specific features not available by default
• Standardize solutions using existing libraries

In summary, using the Library Manager allows adding complementary libraries to the project, expanding development possibilities and making the logic more robust and flexible within MasterTool X.
