FB_TableGeneratorAsciiFile

FB_TableGeneratorAsciiFile 1:

Implements a file read mechanism for a user-defined table (e.g. for use as a transformation table).

Formatting the file:

Drive               Load

0.0        100.0
1.0        110.0
2.0        121.0
3.0        131.0
4.0        142.0
…
FB_TableGeneratorAsciiFile 2:

Limited number of points

The number of points that can be loaded with this class is limited by the parameter Tc3_PlasticBaseAppStaticParams.cnMaxTrafoPoints. If a file contains a larger number of points, the limit in the library settings must be adjusted accordingly!
