Navigation Setup → Advanced setup → Locking status
Description Indicates the write protection with the highest priority that is currently active.
User interface • Hardware locked
• SIL locked
• CT active - defined parameters
• WHG locked
• Temporarily locked
Additional information Meaning and priorities of the types of write protection
• Hardware locked (priority 1)
The DIP switch for hardware locking is activated on the main electronics module. This
locks write access to the parameters.
• SIL locked (priority 2)
The SIL mode is activated. Writing access to the relevant parameters is denied.
• WHG locked (priority 3)
The WHG mode is activated. Writing access to the relevant parameters is denied.
• Temporarily locked (priority 4)
Write access to the parameters is temporarily locked on account of internal processes in
progress in the device (e.g. data upload/download, reset etc.). The parameters can be
modified as soon as the processes are complete.
On the display module, the -symbol appears in front of parameters that cannot be
modified since they are write-protected.
Access status tooling
Navigation Setup → Advanced setup → Access status tooling
Description Shows the access authorization to the parameters via the operating tool.
Additional information The access authorization can be changed via the Enter access code parameter
(→ 140).
If additional write protection is active, this restricts the current access authorization
even further. The write protection status can be viewed via the Locking status
parameter (→ 139).
