# Header data The header data are basic and correction values required for calculating the operating data and, consequently, also for the indices. Header data is used as expert information.
| Header data versions:
> Operating data - version | DIWA.5 |
> | E300 | E300.1 |
> 5 | E300-D2.3.0.0 |  |
> 6 | E300-D2.4.0.0 |  |
> 7 | E300-D2.5.0.0 | E300.1-D5.0.0.0 |
> 7 | E300-D2.5.1.0 | E300.1-D5.0.1.0 |
> 7 |  | E300.1-D5.1.0.0 |
> 7 |  | E300.1-D5.2.0.0 |
> 8 |  | E300.1-D5.3.0.0 |
> 9 |  | E300.1-D5.8.0.0 |
| Header data contents:
> Header data | Description / note | Example |  |
> |  | Raw value | Formatted value |
> Version number | The version number indicates the version of the operating data structure and the corresponding system (E300 / E300.1). | 262144 | 4 |
> Start address | The memory start address for the operating data in the transmission control unit | 4196352 | 0x00408000 |
> Correction value, axle ratio i(A) | Corrects the value for the axle ratio stored in the dataset to suit the actual vehicle axle ratio. | 5,970 | 5,970 |
> Dataset value, dynamic tyre radius in [mm] |  | 486 | 486 |
> Correction value for transmission ratio | This value is always 1,000 | 10,000 | 1,000 |
> Parameter TimeSlicesOfNoCumulation | Operating data is cumulated only if specific operating conditions are provided. Non-cumulative times are indicated here. | 12766725 | 354:37.52 |
> Parameter ReasonsForNoCumulation | Reasons for not cumulating, for example: Axle ratio i(A) missing. The reasons are encoded in hexadecimal. | 16777216 | 0x01000000 |
> Parameter TimeSlicesOfConsistence | There are reasons that might involve inconsistency between the operating data. The duration of inconsistency is indicated here. | 0 | 00:00.00 |
> Parameter ReasonsForNoConsistence | Reasons for inconsistency of the operating data encoded in hexadecimal | 0 | 0x00000000 |
> Parameter NumOfOperationCycles | Describes the number of operating cycles. | 24 |  |
> Parameter NumOfOperationCyclesHidden | Describes the number of operating cycles. | 25 |  |
