Authentication and Access Control

Authentication ensures that only authorized users can make changes that affect system behavior.

Web Server Authentication

• Configuration changes made through the PCMM2G web server are permitted only for authenticated users.
• See User Authentication.

Authenticated KAS-IDE Access to PCMM2G

Engineering operations initiated from KAS-IDE include:

• Project download.
• Project start and stop.
• Controller configuration modification require authentication using the existing PCMM2G Web server username and password.
• See Connect to the Controller.

By default:

• Authentication is required for KAS-IDE connections that perform protected actions.
• Unauthenticated users cannot overwrite or control the active controller configuration.
• An explicit configuration option is available to allow unauthenticated KAS-IDE access in controlled environments, with clear indication and warning of the reduced security posture.
  • See Security tab.
  • These mechanisms prevent unauthorized or accidental controller modification, even when users have network access or project files.
