These operating instructions describe the SMARTCAMERA product from the Balluff Vision
Solution BVS SC product family as well as the data interfaces and the startup for an immediate
operation.
The web-based software interface integrated in the SMARTCAMERA is described in the
separate software manual (BVS Cockpit manual).
Both manuals are available on the Balluff product website via www.balluff.com or via the help
system of the BVS Cockpit interface.
The SMARTCAMERA was developed to identify objects in automated industrial environments
via optical codings (barcode, 2D codes or plain text) and to recognize and verify characteristics
of objects such as presence, contours, dimensions, colors and positions. The test results can be
processed in a flexible way and forwarded to the higher-level controller. Some outstanding
properties are:
– Complete camera control and evaluation integrated in the device
– Simple camera access from the network
– Simple and user-friendly settings, control of camera without additional software
– Simple, user-guided operation
– Support of Industry 4.0
– Integrated, flexible displays of process statistics
These characteristics make it possible to easily create test and identification tasks in automation,
to flexibly check the status of the test process, to monitor long-term processes in a clearly
arranged way.
Hence, the SMARTCAMERA perfectly supports logistics processes and quality assurance in
different industries.
These operating instructions apply to the following variants of the SMARTCAMERA:

The Balluff SMARTCAMERA BVS SC is a camera for the acquisition and analysis of black-and-
white and color images. Application areas are optical identifications of codes and plain text,
inspections for quality assurance and the measurement of objects. The camera can also be used
in robot environments.
With the Gigabit LAN interface, the host industrial system can affect the processes in the camera
and receive customer-specific processed result data.
The product is suitable for use in harsh industrial environments (IP67 with lens protection,
standard M12 industry plug connections, standardized industry network connections).
Since the complete software is located on the SMARTCAMERA itself, no external software is
required for the configuration and monitor display. Using standardized web browsers such as
Google Chrome, Mozilla Firefox or Internet Explorer, the user can easily connect with the
SMARTCAMERA and work in the Balluff BVS Cockpit interface developed specifically for
camera systems.

The maximum load on the supply voltage output is 1.2A.
The digital sensor inputs correspond to the guideline concerning inputs, EN61131-2,
Type3.
Every output may be loaded with a maximum current of 100mA.
The power plug connector supplies the SMARTCAMERA with the supply voltage and offers two
I/O-24V switching signals (I/O0 & I/O1) for the connection with sensors, actuators or PLC.
These two inputs and outputs feature a push-pull output stage. This allows using the output
signal for PNP logic as well as NPN logic. The input stage always features PNP logic.
I/O 0 & I/O 1 (power plug connectors)
Operation as input
Voltage Signal 0 0…5 V < 2 mA
Signal 1 11…30 V 2…5 mA
Delay < 160 µs
Operation as output
Voltage Signal 0 0 V (+VD)100 mA max.
Signal 1 24 V (VDC – VD)100 mA max.
Voltage drop VD< 2 V
Delay < 10 µs
See also the guideline on digital inputs, EN 61131-2, Type 3.
Below are examples how inputs and outputs must be connected to obtain input and output
function.
Notes
I/Os of the same name are logically connected with each other.
When operating the I/Os as output, then e.g. I/O0 is connected at the power connec-
tion and I/O0 at the IO connection.
If the I/Os are configured as input, their signals are ored. A 1 signal is recognized if a 1
signal is present either at I/O0 of the power connection or I/O0 of the I/O connection.
Input connection
If I/O0 is configured as input, it is sinking and can be connected directly with the PNP output of
a sensor, a PLC. A 1 signal is being detected if the input is connected with the supply voltage. A
0 signal is being detected if the input is set to ground or is not connected.
If an NPN device is to be connected to the input, then an external level converter must be
connected upstream.

Output connection
If I/O0 is configured as output, the supply voltage is applied at the output and the actuator, PLC
input is supplied with it if 1 is being output. The output is connected with GND if 0 is being
output. The output current of an I/O may not exceed 100mA.
If the output is being overloaded, e.g. by a short circuit, it is switched off and periodically
checked whether the fault occurrence is still present. If the error was removed, the output is
again in normal operating state without a reset.
PNP output connection
PNP logic is predominantly used in Europe. The output is sourcing, so that the load between I/O
and GND must be switched accordingly. The load is connected with supply voltage if 1 is being
output.

The I/O light interface provides 24 volt and two I/O signals (I/O6 & I/O7). These I/Os, similar to
the two I/Os at the power plug connectors (see “Power” on page16), are equipped with a
push-pull output stage and a PNP input.

Among other things, this makes it possible to easily connect lighting equipment to the SMART-

The IO interface furnishes six galvanically isolated I/O 24V switching signals for the connection
with sensors, actuator or PLC.
All inputs and all outputs have a Common In or Common Out reference potential. This allows
using the I/Os either for PNP logic or NPN logic. A mixed mode (PNP and NPN at the same time)
is not possible.
These I/O signals can be used to control the camera or transfer individual information to the host
system. As a result, the image acquisition can be triggered via these I/O signals. Outputting a
binary analysis result is also possible. The assignment of the I/O signals is done via the BVS
Cockpit interface (see “Digital I/O interface” on page29).

1) The supply voltage for the I/O of the I/O interface is galvanically isolated from the operational
voltage of the SMARTCAMERA.
2) The maximum current for Common In and Common Out is 630 mA.
Below are examples how inputs and outputs must be connected to obtain input and output
function.
Notes
I/Os of the same name are logically connected with each other.
When operating the I/Os as output, then e.g. I/O0 is connected at the I/O connection
and I/O0 at the power connection.
If the I/Os are configured as input, their signals are logically combined with OR. A 1
signal is recognized if a 1 signal is present either at I/O0 of the power connection or
I/O0 of the I/O connection.

PNP mode
PNP logic is predominantly used in Europe. The output is sourcing, the input is sinking.
To operate the I/O port in PNP mode, Common Out must be supplied with +24 V (19.2…30 VDC)
and Common In with 0 V.
If I/O0 is configured as input, it can be connected directly with the PNP output of a sensor, a
PLC or similar. A 1 signal is being detected if the input is connected with Common Out. A 0
signal is being detected if the input is set to Common In or is not connected.

If I/O0 is configured as output, the output is connected with Common Out and the actuator,
PLC input or similar is supplied with it if 1 is being output. The output is high-resistance if 0 is
being output.

The output current of an I/O may not exceed 100mA. If the output is being overloaded, e.g. by a
short circuit, it is switched off and periodically checked whether the fault occurrence is still
present. If the error was removed, the output is again in normal operating state without a reset.
It is also possible to use input and output functions at the same time. In the following example,
I/O0 is configured as output and I/O1 as input.
