Individual images from a camera are archived in a camera archive. These are shown in the Camera archive menu mask and by calling up the camera archive via the visualisation.
The maximum size of a camera archive is determined by the two parameters "Ring memory" and "Max. memory (bytes)". The value that is reached first in each case limits the size of the archive.
The archives are saved retentively.
Camera archives can be imported and exported via the Global Library.

1.1.Data
Designation
The camera archive is maintained under this term in the HS/FS Expert.
Camera archives can be searched via the end point interface, where a word from the designation begins with the search word used there.

Camera
The camera is assigned here. The images are archived from this camera via the command: Archive camera image.
The image format in the archive results from the dimensions in the camera definition (Master data/Camera).
The image format in the archive results from the dimensions in the camera definition (Master data/Camera).
Ring memory
The number entered here specifies the maximum number of images in the camera archive. If the number is reached, the oldest image is replaced by the newest one. See also: Limit values.
Max. memory (memory)
The number entered here specifies the maximum memory capacity reserved for the camera archive. If all the defined camera archives together occupy too much memory, an error message is output during the check. If a value is specified for an individual camera archive that is too large, the input is shown in red.
See also: Limit values.
If the limit value entered here is reached, the oldest image is replaced by the newest one. If the specification made here is larger than the memory physically available on the HS/FS, then the physically available memory is used as the limit and the specification made here is ignored.

If the limit value entered here is reached, the oldest image is replaced by the newest one. If the specification made here is larger than the memory physically available on the HS/FS, then the physically available memory is used as the limit and the specification made here is ignored.
Note
If the memory of the HS/FS is no longer sufficient to back up the retentive memory cyclically, images are removed from camera archives in order to create space. For more information, see Retentive memory, Section Cut off.
Max. memory (unit)
The unit for the value of the max. memory can be specified here. You can select:
- Bytes
- KB (1 KB = 1024 Bytes)
- MB (1 MB = 1024 KB)
Note
Please note that the entered value is not automatically recalculated by the program if the unit is changed!
1.2.End point
Camera archives can be accessed via the end point interface of the HS/FS.
