How to gain access to M241 controller for which password is lost for user enabled access rights

The only way to gain access to M241 controller that has user access-rights enabled and for which user do not have the password(s) is by performing an Update Firmware operation.

This clearing of User Rights can only be accomplished by using a SD card or USB key (depending on the support of your particular controller) to update the controller firmware.

In addition, user may clear the User Rights in the controller by running a script.
This effectively removes the existing application from the controller memory, but restores the ability to access the controller.
