Table 7.3:
The bar code readers of the BCL
opto-decoupled switching inputs and outputs SWIO_1 ... SWIO_4.
The two switching inputs/outputs SWIO_1 and SWIO_2 are located on the SW IN/OUT M12
socket. The other two (SWIO_3 and SWIO_4) of the four freely configurable switching inputs/
outputs are located on the PWR M12 connector and are described in chapter 7.2.1.
Described in the following is the external wiring for use as a switching input or output; the
respective function assignments to the switching inputs/outputs can be found in chapter 10.

Figure 7.5:
 If you use a sensor with a standard M12 connector, please note the following:
• Pins 2 and 4 must not be operated as switching outputs if sensors which function as
inputs are also connected to these pins.
If, for example, the inverted sensor output is connected to pin 2, and pin 2 of the bar code
reader is, at the same time, configured as an output (and not as an input), the switching
output malfunctions.
