Web-based Management 2:
Security - User management

Valid from firmware release 2025.0 - for earlier firmware see WBM User Authentication

By default, on a PLCnext Control only a single user is configured and assigned to the Admin user role.

Of course, other users and user roles need to be assigned, once the controller is put into production, which is done by means of the User management WBM 2 page. The procedure is designed to be mostly selfexplanatory: By clicking the icon, you'll be led through a step-by-step configuration.

Security iconPlease note the guidelines in our PLCnext Technology ‑ Security Info Center.
For developing secure-by-design, IEC 62443‑2 compliant applications with PLCnext Technology, get a good grasp of the concepts used in the Security context.
