EVALUATION MODE:
This function field serves for setting the evaluation mode at the
colorSENSOR OT-3-...-200-20 color sensor.
All the evaluation modes apply to all CALCULATION MODE = X/Y INT, s/i M, X/Y/INT and i/i/M.
The TEACH TABLE is correspondingly adapted depending on the CALCULATION MODE.
The following explanation uses CALCULATION MODE = X/Y INT.
FIRST HIT:
The currently measured color values are compared with the
default values in the TEACH TABLE, starting with teach-
color 0. If in the row-by-row comparison the current color
values correspond with the teach-parameters entered in
the TEACH TABLE, this first "hit" in the TEACH TABLE is
displayed as a color number (C-No.) and is output at the
digital outputs (OUT0 ... OUT4) according to the settings of
the OUTMODE parameter (see OUTMODE).
If the current color does not correspond with any of the
teach-colors, the color code C-No. = 255 will be set ("error
status").
Tip! This mode is used if only one color is taught, and this
color must be checked to avoid "drifting away". With the
rising tolerance windows this can be detected very well,
and countermeasures can be initiated, if necessary.
Tip! If, for example, only the X/Y coordinates should be
checked, and intensity INT is of no importance, a tolerance
of 4000 can be selected for ITO. This inspection criterion is
thus always fulfilled.
Tip! Values can be entered in a cell of the table either by
double-clicking on the respective cell, or by highlighting the
respective cell and then pressing F2 .
Tip! The teach colors are only activated when the SEND
button is pressed!
