Supervision of Hardware Configuration
The modular hardware concept requires adherence to some rules within the product family and the modular
system. Configuration errors show that the hardware configuration saved in the device does not agree with
the hardware actually detected. Impermissible components and unallowed combinations must be detected
just as missing configured components are.
Depending on the type and severity of error, the following error responses will result: The identified hardware
configuration errors are assigned to the defect severities as follows:
Configuration errors where the device remains in operation.
The failure is indicated. The signals/data affected by the failure are marked as invalid. In this way, the affected
protection functions can go into a secure state. Such errors are, for example, errors in IE converter configura-
tion (loss and errors).
Fatal configuration error: The device goes permanently out of operation into a secure state (fallback
mode).
Such errors are, for example:
•
Missing hardware module (module x)
•
Incorrect hardware module (module x)
•
Incorrect hardware combination
•
Incorrect plug-in module (module x)
You can find the detailed description, in table form, of the error reactions at the end of chapter 8. You will find
corresponding corrective measures there. You can resolve configuration errors through another synchroniza-
tion with DIGSI.
