1. ARCHITECTURE

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

Figure 1. Computer running MasterTool X

2. DEVELOPMENT

The project tree (TreeView) of MasterTool IEC XE organizes all the elements of the application, allowing the user to quickly access programs, variables, libraries, and system settings. Below is a brief description of each presented item:

Figure 2. TreeView - Application

• Device (XF325)

Represents the physical PLC used in the project.
Contains all hardware-related configurations and the application linked to this device.

• PLC Logic

Area related to the main control logic of the controller.

• Application

It is the core of the project, where all elements of the developed application reside, such as programs, variables, and settings.

• Bill of Materials

Project materials list.
Used for documentation and inventory of components used.

• Configuration and Consumption

Area dedicated to analyzing the current consumption of the PLC's internal power supply

• SystemGVLs

List of system global variables (already prepared).
Includes:

1. IntegratedIO → Physical input and output variables
2. Module_Diagnostics → Module diagnostics
3. Special_Variables → Special variables (e.g., pulses, system)
4. System_Diagnostics → General system information

• SystemPOUs

Internal system programs.
Example: MainPrg (PRG) → Standard main system program

• UserGVLs

User-created global variables.
Organized into lists, such as:

1. Disables → Blocking variables
2. Qualities → Signal qualities
3. ReqDiagnostics → Diagnostic requests

• UserPOUs

User-created programs.

1. StartPrg (PRG) → Executed at startup
2. UserPrg (PRG) → User's main program

• Library Manager

Library manager.
Allows adding external libraries (e.g., Util) with new blocks and functions.

• Task Configuration

PLC task configuration (execution cycle).

• MainTask → Main system task
• MainPrg → Program linked to the task execution
