Disabling User Management
Important
After disabling the user management, your controller is accessible again for everyone in the network of the controller. Therefore, you should only do this in justified exceptional cases or if the clients used do not support any user management.
Tip
For enabling the user management, at least one development system CODESYS V3.5 SP16 is necessary. This means that, in the case of enforced user management which has not been enabled yet, you cannot connect to an older development system.
To reset a forced, active user management to "Optional", proceed as follows:
Double-click the controller in the device tree, on the Communication Settings tab click Connect network, and establish the connection to your controller.
On the Communication Settings tab, select Device → Change Communication Policy.
In the Change Communication Policy dialog, in the Device User Management area, select Optional user management as the New Policy and click OK.
The security policy for device user management is set to "Optional".
Establish the connection to the controller and in the Online menu click Reset Origin Device. This deletes the still active user management and the setting that the controller should only have an optional user management is set. Note: In CODESYS V3.5 SP16 Patch 20 and higher, you can exclude the boot application from the delete operation when you execute Reset Origin Device.
