This tutorial will present what is contained in the Application tab of the TreeView of a project in MasterTool X.
Components
Equipment: 1 computer/laptop.
Software: MasterTool X
Tutorial Sections
- ARCHITECTURE
- DEVELOPMENT
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:
- IntegratedIO → Physical input and output variables
- Module_Diagnostics → Module diagnostics
- Special_Variables → Special variables (e.g., pulses, system)
- 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:
- Disables → Blocking variables
- Qualities → Signal qualities
- ReqDiagnostics → Diagnostic requests
UserPOUs
User-created programs.
- StartPrg (PRG) → Executed at startup
- 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
