# Voith EOL By default, the control unit software is configured using a dataset. The parameter values of this dataset are influenced by engine and vehicle data, transmission parameters, the required shift program and other fundamental variables such as communication protocols, OEM-dependent settings, etc... In order to achieve more flexibility regarding the characteristics of the control unit software, you have not only the option of flashing datasets but you can also adjust individual EOL parameters. At present, approx. 200 parameters are vehicle-specific in DIWA.5. This is why they are potentially required for a complete EOL configuration.
| Operational principle:
The initial loading of a dataset simultaneously fills the complete EOL area. You can change individual EOL parameters subsequently using the Voith EOL Manager. For an individual dataset parameter A that means that it is copied to a corresponding EOL parameter A when the dataset is loaded for the first time. The software accesses the corresponding EOL parameter A instead of the dataset value A. This EOL parameter can be changed using the Voith EOL Manager.
| Reflashing a dataset:
| Each time a dataset is loaded again, the dataset that is currently loaded in the control unit decides how the EOL area is to be treated. The dataset parameter "EOL_ENABLE_OVERWRITE_BY_DS_SEL" is used for this purpose. It controls whether EOL groups are overwritten or retained. The behavior of the individual group is displayed in the Voith EOL Manager.
