10.16.2 Module 91 – AutoReflAct (automatic reflector activation)
PROFINET-IO module identifier
Module-ID 1091
Submodule-ID 1
Description
The module defines the mode of operation of the laser scanner for controlling the reading
gate.
The AutoReflAct function uses the scanning beam to simulate a photoelectric sensor and
thus permits an activation without additional sensory mechanism. This is achieved by
directing the scanner with reduced scanning beam towards a reflector mounted behind the
conveyor path. As long as the scanner is targeted at the reflector, the reading gate remains
closed. If, however, the reflector is blocked by an object such as a container with a bar code
label, the scanner activates the read procedure, and the label on the container is read. When
the path from the scanner to the reflector has cleared, the read procedure has completed
and the scanning beam is reduced and again directed onto the reflector. The reading gate
is closed.

Mode
This parameter activates the
function of the laser scanner.
If "Autom. reading gate con-
trol" is set as the parameter
value, the BCL activates the
reading gate automatically if
the reflector is obscured.

Debouncing
The parameter defines the
debounce time in scans for the
reflector detection
With a motor speed of 1000,
1 scan corresponds to a
debounce time of 1ms.
