The source code upload is an essential feature in automation because it allows you to recover the complete project directly from the PLC. It is widely used in maintenance, diagnostics, or when the original project is not available.

Importance of the upload

Uploading enables:

  • Recovering the project directly from the PLC
  • Accessing logic, variables, and comments
  • Performing maintenance without having the original file
  • Ensuring system continuity

Important:
Upload is only possible if the source code was previously sent to the PLC.

Checking source code availability

To check if the PLC has source code:

  1. Access the File menu
  2. Click on Upload Source Code

Device Mapping

After this:

  1. A window similar to Easy Connection will open
  2. Click to map the network
  3. Locate the desired PLC
  4. Select the CPU
  5. Click OK

Verification Result

MasterTool will inform you:

  • If there is no source code:
    • The upload cannot be performed
  • If there is source code:
    • The system will proceed to the next step

Selecting the save location

In the next window:

  1. Choose a folder on the computer
  2. Define where the project will be saved

Content configuration

In the Contents tab:

  • Check all available options

This ensures the project is fully recovered, including:

  • Logic
  • Variables
  • Comments
  • Libraries
  • Project structure

Project extraction

After configuring:

  1. Click Extract

The system will:

  • Download the source code from the PLC
  • Rebuild the project on the computer

Opening the project
 

At the end of the process:

  • MasterTool will ask if you want to open the project automatically

If confirmed:

  • The project will load
  • It will be ready for editing and analysis

Applications in automation

  • Project recovery
  • Field maintenance
  • System auditing
  • Fault diagnosis
  • Operational continuity
     

Important notes

  • Only works if the source code is in the PLC
  • It is recommended to always send the source code at the end of the project
  • Checking all contents ensures complete recovery
  • The process may take a few minutes
