Product description
4.6.7
Reading operation mode
There is only one
object
in the reading field during
start/stop operation
, i.e. all the read
codes should be unambiguously assigned to the object. The start and stop of the reading
process control one/two reading pulse sensors at the beginning and at the end of the read-
ing field as standard. The distance between each sensor is determined by the size of the
reading field. The reading process can be alternatively controlled with command strings via
the data interface. The output of the reading results is carried out either at the end of the
reading pulse (the rear edge of the object has left the end of the reading field) or during the
reading pulse if certain configurable conditions have been fulfilled.

Output format
The reading result (decoded codes) is displayed via selectable physical interfaces. Two dif-
ferent output formats (telegrams) can be defined for this task, one format for "No Read" and
one for the heartbeat (signalisation of readiness).
