The AT box is not ready. An expansion module conforming to the AT specification has either no
functionality or restricted functionality.

DBX103.6 HMI temperature limit
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change 0 → 1
The environment conditions of the limit value are in the permitted tolerance range of 5 to 55 degree
C.
Signal state 0 or
edge change 1 → 0
The temperature range was either exceeded, or the temperature fell below the limit.
The temperature monitor has responded and the PCU is disabled.
DB10
DBX103.7 HMI battery alarm
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change 0 → 1
The battery monitor has responded. Power failure can cause the loss of recently changed data and
a correct device configuration. A corresponding HMI alarm is reported. The HMI buffer battery
should be checked. An insufficient battery voltage also affects the current time on the operator
interface.
Signal state 0 or
edge change 1 → 0
No HMI battery alarm is present.

DBX104.7 NCK CPU ready
Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 The NCK CPU is ready and registers itself cyclically with the PLC.
After a correct initial start and the first complete OB1 cycle (initial setting cycle) the PLC and NCK
continuously exchange sign of life signals.
The PLC basic program sets the interface signal "NCK CPU Ready" to 1.
Signal state 0 The NCK CPU is not ready.
If a sign of life is not received from the NCK, the PLC/NCK interface is neutralized by the PLC basic
program and the interface signal "NCK CPU Ready" is set to 0.
The following measures are introduced by the PLC basic program:
• Status signals from NCK to PLC (user interface) are deleted (cleared)
• Change signals for help functions are deleted
• Cyclic processing of the user interface PLC to NCK is terminated.
