Access management

The access management system controls which control signal source may access the user interface of the software module.

Each control signal source may request access and receives a corresponding feedback message as to whether access is possible.

The control signal sources available for the software module are HMI, UI, PD, and UPPER. This order corresponds to the priority of the control signal sources regarding access.

A separate access management system exists for each single axis. If access is granted via UI or HMI for a single axis, the software module cannot access it.
