Error Display

Cause
The following causes are possible:
– Double assignment of I/O addresses
– Double assignment of hardware interrupts and/or DMA channels
– Signal frequencies or signal levels are not met
– Different connector assignments
Remedy
Check your computer configuration:
S If the computer configuration is the same as when your PC was delivered,
please contact your technical support team (Chapter 8).
S If the computer configuration has changed, re-establish the configuration you
had when your PC was delivered. Remove any modules from other manufactu-
rers. Perform a complete restart on your PC.
– If the PC still crashes, you must contact your technical support team.
– If the error no longer occurs, the module you used from another manufactu-
rer was the cause of the fault. Replace this module with a Siemens module,
or contact the module supplier.
