During fail-safe operation, you must be aware that the following error cases may arise:
● HMI does not start
If the HMI device does not start, the wires at interface X10 in the connection box may
have been crossed. Check the connected wires and change the connections if
necessary.
● Internal error
If an internal error occurs in the HMI device, the HMI device displays the "Fatal Error"
message. Safety functions are no longer available. If the error persists after resetting the
fail-safe module, contact the Siemens hotline. You can find additional information in the
following section: "Fatal Error" dialog (Page 213)
● Communication error
If a PROFIsafe communication error occurs on the HMI device, the safety functions are
not available. The F-CPU triggers an emergency stop and switches the plant or plant
area into a defined safe operating state. When PROFIsafe communication is possible
again, the message "Confirm communication error" is displayed. Confirm the message
with the enabling button. You can find additional information in the following section:
"Confirm communication error" dialog (Page 213)
● SCALANCE firmware error in the connection box
If a SCALANCE firmware error occurs in the standard or advanced connection box, press
the SET button shown in the figure below for at least 15 seconds.
The SET button resets the firmware of the internal SCALANCE switch to the factory
settings.
Note
The setting for safety
-related operating mode of the connection box is retained.
You can find additional information about the SET button in the following document:
