8.1.7 Last eight fault codes and error codes
Every time, a fault is thrown which triggered a fault reaction, information about the fault is stored to the
<StandardErrorField> (0x1003) parameter array. The <StandardErrorField> (0x1003) parameter array con-
tains a list of up to 8 entries. This error code provides information about the reason of the error. The parame-
ter <NumberOfErrors> (0x1003) holds information about the number of errors currently recorded. Every new
error is stored in the first element of the parameter array <StandardErrorField> (0x1003), the older ones move
down in the list. If the maximum number of entries is reached and a new fault occurred the oldest fault infor-
mation will be deleted.
Writing the value 0 to the object <NumberOfErrors> (0x1003), sub-index 0, deletes the entire error code en-
tries.
8.1.7.1 Object 0x1003: Predefined error field
This object contains the last eight error codes, fault codes and the number of recorded errors.
Value description
Example
The parameter <StandardErrorField> (0x1003), sub-index 1 holds the decimal value 3167536 (corresponds to
0x305530 hex).
The coding of the value is shown in the following table:
Result:
Only the first eight elements of the parameter array <StandardErrorField> (0x1003), sub-index
1…8 are used.
