SIMATIC Box PC 620  Manual

A5E00131465-01

The PC crashes during power up.

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

Check your computer configuration:

 If the computer configuration is the same as when your PC was delivered,

please contact your technical support team (Chapter 8).

 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.
