Product description
4.6.2
Object trigger control
In order to start an object-related reading process, the bar code scanner requires an appro-
priate external signal (trigger source) for reporting an object in the reading area. The start
signal is emitted via an external reading pulse sensor (e. g.
photoelectric reflex switch
) as
standard. As soon as an object has passed the reading pulse sensor, a time window opens
in the bar code scanner (“reading gate“) for the reading process.
Alternatively, a command activates the reading process via a data interface or the CAN-SEN-
SOR network. In Automatic Cycle mode, the actual bar code scanner generates the reading
gate internally with an adjustable mark-space ratio.
The reading pulse can be ended in a number of ways: With external triggering by the reading
pulse source or a command, internally by a timer or an evaluation condition to be met.
4.6.3
Increment configuration
The bar code scanner receives information about the conveyor speed from an external in-
cremental encoder, for example. The incremental encoder delivers pulses which are used
to determine the current conveyor speed.
The conveyor speed results from the number of impulses and the resolution of the external
incremental encoder.
