After Fieldgate has been commissioned, a local hardware lock can be set that prevents any

6.5.2 Deactivating the hardware lock
Note!
• The service interface is not affected by the hardware lock and can always be used to access the
Fieldgate!
• The lock cannot be deactivated when the Fieldgate is booting - this causes a device reset.
The lock can be deactivated temporarily during normal operation by pressing the reset button for
one second, see Chapter 9.2. This allows access for five minutes, after which the lock is enabled
again. Pressing the reset button for 5 seconds enables the lock immediately.
The lock can be deactivated permanently by first temporarily unlocking it, then disabling it by
unchecking the
Enable Configuration Hardware Lock
box and pressing
Send
. Alternatively this
can be done via the Service Interface.
