How can I reset the password of a zenon Service Engine/Runtime User?

Resetting a password in the zenon Engineering Studio can be essential for maintaining security and managing user access to your project. zenon offers two different methods to reset a password: one through the zenon Engineering Studio and the other through the zenon Service Engine. In this knowledge base article, we will walk you through both of these methods step by step.

  1. Access User Administration: Launch the zenon Engineering Studio and open your project. In the navigation menu, click on "User Administration" > "Users"
  2. Select the User: From the list of users in your project, select the user for whom you want to reset the password.
  3. Open User Properties: Right-click on the selected user and choose "Properties" from the context menu or just click on the user.
  4. Set a New Password: In the User Properties dialog box, navigate to "Password". Click to change the password.
  5. Transfer Changes: After setting the new password, click on the "Configure Service Engine changable files" button to allow zenon to overwrite existing user data. Ensure that the checkbox labeled "Do not generate and transfer" is not selected to ensure the changes are saved and propagated to the zenon Service Engine.
