CCD array camera OptoLine OL 80..
Counting direction, contrasting edges
Example:
right
camera in direction of
web travel
7.7.1 Configuring the first measured value:
A CAN address should be set for each measured value to be
output. The CAN address of the first measured value is usu-
ally the address specified on the module reference on the
camera or in the block diagram.
The following examples all refer to the illustration on page 16.
7.7.1.1 Setting the CAN address
➜
Call up the setup editor.
➜
Enter the camera device number in parameter 0.
1 for measured value 1 (right sensor)
➜
Enter the camera group number in parameter 1.
0 for measured value 1
7.7.1.2 Determining the operating mode
➜
Set the camera operating mode in parameter 6:
"1" = contrasting edge
"2" = center between two contrasting edges.
1 for measured value 1
➜
Enter the contrasting edge number, the position of which is to be
output, in parameter 7. The preceding sign indicates the direction
of counting, see fig. opposite:
The following applies for cameras mounted in the direction of
right
web travel:
No pre-sign = direction of counting from outside to inside
Negative pre-sign = direction of counting from inside to outside.
The following applies for cameras mounted in the direction of
left
web travel:
No pre-sign = direction of counting from outside to inside
Negative pre-sign = direction of counting from inside to outside
1 for measured value 1
➜
Enter the contrasting edge number in parameter 8 (only if camera
operating mode 2 is set).
No entry for measured value 1
7.7.1.3 Emergency guiding
➜
If necessary, enter the address of the sensor that is to perform
emergency guiding in parameter 9.
no entry for measured value 1
If the camera is only to output one measured value, it is now
ready for calibration.
