Parameters
5.4.2.2.1
Distribution
The trigger signal communication is activated/deactivated and assigned to a communicati-
on network via the
• D
EACTIVATED
: The trigger is not distributed to other network users.
• CAN: In a group of devices that communicate with each other via the CAN network, the
signal for opening the reading gate can be distributed. This involves an appropriate trigger
signal being received by one of the devices – usually the master – and distributed to the
remaining devices in the CAN network
5.5
Position
The coordinates and angles of the LECTOR
®
620 above the conveying system are defined on
tab. In the application, this means that objects can be clearly assigned, a defi-
ned position can be output, and the objects can be aligned in relation to the reading point.
5.5.1
Coordinates
group, the position of the device above the conveying system is defined
in relation to a neutral point. Establishing the device position makes it easier to map the po-
sition of an identified object at a later stage.
Looking in the conveying direction, the neutral point can generally be found on the bottom
right-hand edge of the conveying system.
5.5.1.1
X-coordinate
The distance between the reading device and the reference point in the X-direction, i.e.
along the length of the conveying direction, is entered under the
parameter.
5.5.1.2
Y-coordinate
The distance between the reading device and the reference point in the Y-direction (at 90°
to the conveying direction), is entered under the
parameter.
5.5.1.3
Z-coordinate
The distance between the reading device and the reference point in the Z-direction, i.e. the
distance above the conveying line, is entered under the
parameter.
5.5.2
Angle
The three-dimensional position of the camera is defined in the
group.
5.5.2.1
Alpha
The device's Alpha angle in relation to the code and trigger position is defined under the
Example: Setting the angle to 90° or 270°. The reading is taken perpendicular to the con-
veying direction.
