Processing Setup
Object with
DMC
The objects with the data matrix code are fed past the sensor head with a suitable
conveyor.
They must be located fully within the sensor field of view when being read.
In the training mode, the character content of the code is saved.
In the evaluation mode, the current code is read and, if required, compared with the
saved content of the trained code. Depending on the results of the read operation,
the digital output signals are set: READ (code was localized and decoded),
MATCH (code matches the learned code), N_OK (code was not legible).
The result of the read operation is output via the RS-232 interface or via
PROFIBUS. It is also possible to filter the read character string and to append
additional characters at the start or end.
Triggering
To read the data matrix code, you must make sure that the code is completely
within in the sensor field of view and clearly visible.
The data matrix code is captured at the trigger time. In this case, you generate an
exact trigger signal at the trigger time, for example with a laser light barrier.
You can check your settings with the setup software of the VS 130.
