The device
crashes during
startup
•
Redundant I/O addresses
•
Redundant hardware interrupts
and/or DMA channels

Fluctuation of signal frequencies
or levels

Different pin assignment
Check your computer configuration:
•
If the computer configuration corresponds to the delivery
state, contact your technical support team.
•
If the configuration has changed, restore the factory state.
To do this, remove the third-party modules and restart the
device. If the error no longer occurs, the third-party module
being used was the cause of the fault. Replace the thrid-
party module with a Siemens module or contact the module
supplier.
If the device still crashes, contact your technical support team.

Insufficient output of an external
power supply, e.g. UPS

mediately
•
A counter voltage is fed into the
device by connected or installed
third-party components
Clarify the following with the supplier of the component:
•
The component can be operated without an external power
supply.
•
The component can be reconfigured so that it only uses the
external power supply or that of the device.
