Unlock protected block in simatic manager using Microsoft Access

Introduction

This tutorial will guide you through the process of unlocking a protected block in SIMATIC Manager using Microsoft Access. If you're unable to access certain functions in your projects due to protection settings, this method will allow you to modify the settings and regain access.

Step 1: Locate Your Project

• Open Windows Explorer.
• Navigate to the folder where your project files are stored. Typically, this will be in C:\Program Files.
• Identify the specific project you wish to unlock. For example, let's say your project is named "Finance."

Step 2: Open Microsoft Access

• Launch Microsoft Access on your computer.
• Once opened, you will need to open the database file associated with your project.
• Using the file navigation options, locate your project’s file (e.g., Finance.MDB or Finance.STX).

Step 3: Find the Protected Function

• In Microsoft Access, ensure you are viewing all files by selecting "All Files" in the file type dropdown menu.
• Look for the database file that contains the protected block. This file will typically have a .DB extension.
• Open the relevant database file.

Step 4: Modify the Protection Settings

• Once the database is open, you will see a list of blocks. Locate the block number associated with the function you wish to unlock, for instance, Function 2001.
• Click on the block to view its properties.
• At the top of the properties window, you will find a field labeled “Password.” This will show a number that indicates the protection status (e.g., it may show 3).
• Change this number from 3 to 0. This change will disable the protection for that block.

Step 5: Save Your Changes

• After modifying the password status, save your changes in Microsoft Access.
• Close Microsoft Access to ensure all changes are properly saved.

Step 6: Reopen SIMATIC Manager

• Launch SIMATIC Manager again.
• Open your project (e.g., "Finance") and check if the previously blocked function (Function 2001) is now accessible.
• You should see that the function is no longer marked as protected, allowing you to edit and use it freely.

Conclusion

By following these steps, you can successfully unlock protected blocks in SIMATIC Manager using Microsoft Access. This simple modification can help you regain access to essential functions in your projects. If you encounter any issues, double-check each step to ensure all settings were correctly modified. Enjoy working with your newly accessible functions!
