# Options tab
General and frontend-specific settings
## General
### Data offset
* Data offset in hours:
Number of hours for data offsetting of daily reports
* Data offset in days:
Number of days for data offsetting of monthly reports
* Data offset in months:
Number of months for data offsetting of annual reports
### Password to close the system programs
You can assign a password for exiting the Provider, Database Engine, DDE / OPC Server and Mirror system programs which is then requested to prevent the program from being closed down unintentionally for example.
Note
The password is case-sensitive.
Note
Passwords and changes to them are logged in encrypted form in modification reports.
### Time in minutes until automatic logout
In case of inactivity, the ACRON frontends and the Designer are automatically terminated after this period of time. This option has no effect on ACRON Admin.
If this field is left blank, there is no automatic logout.
Note
If data backup or export is running, and if the ACRON Graph, Alert and Visual module windows are open in online mode, auto logout is disabled.
### Log data modifications
Data changes are logged, and can be viewed in the ACRON Reporter in the modification report.
## Shift times
Display the number of already configured shift times and create, change or delete shift times in the next dialog box. Enter the start of the work shift with the facility to view reports on a shift in the ACRON Reporter.
Note
The precondition is that [Shift reports](/acron-9.3/en/anlagenkonfiguration/berichte.md) are configured.
## Frontends
### Graphical value progression as
The selected display modes are used in the graphical views in the 'Production data' and 'Manual entries' areas of the ACRON Reporter. The following diagrams are available: Line, step, scatter and bar charts.
### Adapt scaling of y-axis to measured value/limit value range
By default, the Y-axis of the preview diagram (Reporter/Production data) is dynamically adapted to the value range.
If this option is active, the scaling of the Y-axis is based on the preset limit values of the process variable concerned. If no limit values are specified, the scaling is based on the measuring range.
### Text in title bar of frontend windows
The text entered here is displayed in the main window of the ACRON frontends after the module name.
### Update data before report output
The report data of the ACRON modules are updated prior to output.
As ACRON may in some circumstances only update compressed report data (such as in the [annual report](https://github.com/Dataforum-Software/gitbook/blob/master/acron/9.3/en/designer/glossar/jahresbericht.md)) on an hourly basis, it may be that the report does not output the latest data status.
### Always check manual entries outside [limit value range](https://github.com/Dataforum-Software/gitbook/blob/master/acron/9.3/en/designer/glossar/grenzwertbereich.md)
Whenever you enter a manual value that is outside the limit range in the input masks the ACRON Reporter asks you whether you want to apply the entry anyway.
### Limit number of report pages to
Enter the maximum number of pages a report may contain here as required. Once this maximum (1-2500) is reached, a notification is displayed and no further pages of the report are generated.
Note
This setting applies to all output modes, including e-mail and archiving to files.
### Limit number of data columns in Reporter to
Maximum number of process variables in the data table (1-100).
Note
The default is 10 columns. If the number is exceeded, the process variables are not displayed at all.
### Output format for online reports
The report is displayed in the format set here. The choices are EMX or PDF.
### Extend time frame for requesting alerts by n seconds
A time frame is defined for alert windows. This window displays all the alerts beginning within the time frame. The listing is regardless of whether the alerts have ended or are still occurring. For example, to also display alerts that are still occurring but that started outside the time frame, you can enter a value in this field by which to extend the range of alert data readout. This does not change the time frame of the alert window.
### Maximum number of alerts to read
Maximum number of alerts outputted in alert windows.
Note
Lowest value = 100, highest value = 10,000
If the number of records in an online window exceeds the value defined here, the window is automatically set offline.
### Maximum number of entries in history of search functions
User-defined number of saved search queries (maximum 100, default 25).
Note
If this value is exceeded, existing entries are overwritten.
## Automatic Server/Client updates
The Service Packs installed on the ACRON Server are installed automatically for all modules on all ACRON Clients.
