Each deposition devices is described by a file info.txt in its subfolder. For the DD0 device in the demo product the content of this file is this:
Left

Top

width

height
12
Number of parameters
3
Parameter 1
BE1 L*
80
90
100
Parameter 2
BE1 a*
-2

Parameter 3
BE1 b*

My BE
BE1
The structure is the following:
The parameter Left, Top, Width and Height define the position of the device in the coating line and its size (all in m). These values are for production simulation only, please do not change.
Very important are the item 'Number of parameters' (which defines the number of parameters, of course) as well as the parameters themselves. If the deposition device produces a layer that contributes to the coating product, the layer thickness would be a parameter to be defined here. A composition parameter of the layer (e.g. its oxygen content) could be another parameter.
The parameters defined in all the deposition device definitions are to be determined by BREIN. They are collected in a list which is used to generate the database of results.
In the demo product we do not specify layer thicknesses but rather generally color parameters. For each deposition device three color coordinates L*, a* and b* are defined as parameters which are to be determined by BREIN. The names of these numbers in DD0 are 'BE1 L*', 'BE1 a*' and 'BE1 b*'.
For each parameter you have to type in 4 lines in the file which must contain the
•name in the first line
•the tolerated minimum of the parameter in the 2nd line
•the target value of the parameter in the 3rd line
•the tolerated maximum of the parameter in line 4
After the parameter section the last 2 lines of the file contain the identifier 'My BE' (do not change it) and the name of the bright eye that monitors this deposition device.
