Overview
As a PROFIBUS participant, the device is equipped with four M12 plugs/sockets which are A- and B-
coded.
The voltage supply (PWR) as well as the four freely configurable switching inputs/outputs (SW IN/OUT and
PWR) are connected there.
The device is designed for use in PROFIBUS DP. An incoming DP IN - PROFIBUS DP is available as a
HOST / BUS IN interface for connecting to the PLC. An outgoing DP OUT - PROFIBUS DP is present as
another second physical BUS OUT interface for setting up the PROFIBUS DP network.
An USB connection is used as a SERVICE interface.

Figure 7.1: Connections of the device
Described in detail in the following are the individual connections and pin assignments.
CAUTION
Do not open the device yourself under any circumstances! There is otherwise a risk of uncontrolled
emission of laser radiation from the device. The housing of the device contains no parts that need to
be adjusted or maintained by the user.
Before connecting the device, be sure that the supply voltage agrees with the value printed on the
name plate.
Connection of the device and cleaning must only be carried out by a qualified electrician.
Ensure that the functional earth (FE) is connected correctly. Unimpaired operation is only guaranteed
when the functional earth is connected properly.
If faults cannot be corrected, the device should be removed from operation and protected against pos
-
sible commissioning.
CAUTION
For UL applications, use is only permitted in Class 2 circuits in accordance with the NEC (National Elec
-
tric Code). The bar code readers are designed in accordance with safety class III for supply by PELV
(protective extra-low voltage with reliable disconnection).
CAUTION
Degree of protection IP 65 is achieved only if the connectors and caps are screwed into place!
