4 Function
The device checks and monitors code content, code properties and code quality. To do this, it creates
image captures with set applications.
The device outputs the results via an Ethernet-based interface (process interface).
In addition, the device has 2 switching outputs for controlling external devices.
4.1 Overview of device functions
• Integrated, configurable code evaluation
• Read different code types with one application
• Process interfaces:
– O2I50x: Ethernet TCP/IP and EtherNet/IP
– O2I51x: Ethernet TCP/IP and PROFINET
• Parameter setting interface: Ethernet TCP/IP
• Control of the switching outputs via the active application or externally via process interface
• Automatic setting of focus, illumination and code parameters during the configuration
• Internal illumination
• Control of external illumination units possible
• Internal and external triggering of image captures
• Data processing with function blocks and logical links in the unit
• Integrated ifm mass storage device saves current configuration for easy device replacement.
Optional storage of error images
4.2 Web front end
The unit has a web front end via which the following information can be retrieved:
• device documentation
• device set-up
• error images
• licences
uEnter the IP address of the unit in a web browser. Example: http://192.168.0.69
4.3 Triggering image captures
1...5 parameter sets can be defined for image captures.
Image captures for code recognition are triggered by an internal or external trigger signal. Depending
on the selected trigger mode, the images are then captured accordingly.
• Internal triggering
– Images are captured continuously with a fixed frame rate.
– Setting via ifmVisionAssistant or teach app.
• External triggering
– Image capture activated by external trigger source (switching signal of a connected sensor) via
the trigger input.
– Image capture activated by process interface command (PLC) via Ethernet.

Multicode Reader O2I5xx

If an internal or external illumination unit is used, it will be switched on with each triggering.
4.3.1 External triggering
For external triggering of image captures, different trigger modes can be used (Ò software manual at
documentation.ifm.com):
• Negative edge
• Positive edge
• Negative and positive edge
• Gated trigger
• Burst trigger
During an active trigger process, no new trigger can be activated. A trigger signal that occurs
too early will be discarded and treated as a “Trigger overrun” error. The ready signal “Ready for
trigger” can be output to a switching output.

t [ms]
Fig.4: Internal debouncing
1: trigger input 2: image capture
The trigger input can be debounced internally
(preset: internal debouncing deactivated). Internal
debouncing prevents several short pulses from
triggering. The pulse must be at least 4ms long to
be recognised as a trigger.
Depending on the electrical installation, debouncing
is not necessary.
A trigger delay can be set.
4.4 Switching outputs
Switching outputs OUT1 and OUT2 are configurable. If an external illumination is connected, only
OUT1 is still available for the application.
The configuration can be set individually for each application using ifmVisionAssistant. The table
below shows the standard configuration.
Output Standard External illumination Process interface
OUT1 For applications via ifmVisionAssistant:

Tab.1: Standard configuration of the switching outputs
The switching output switches as soon as one of the following device states has occurred:
• “Ready for trigger”
The unit signals that a new image can be captured. Only with this device status are trigger
operations processed. For the continuous image capture the status “Ready for trigger” is not
output.
• “Image capture finished”
The unit signals that the image capture is finished. The device status can be used for cascading
devices in order to prevent mutual interference during image capture.
• “Error”
The unit signals an internal error. Detailed information about errors can be requested via Ethernet.
• “Controlled via process interface” (e.g. by PLC)
The device is controlled via the command “O” (Ò Programmer’s Guide).
• “User-defined states”
The user-defined states are changed with the processing of codes (e.g. code found, code matches
the reference, code quality outside the threshold level, etc.).
4.5 Internal illumination
The activated internal illumination can improve object recognition. The 4 illumination LEDs can be
activated separately.
The internal illumination is set via the ifmVisionAssistant software.

uUse the laser markings to align the unit (Ò Aligning the unit and object/13).
Information about available accessories at www.ifm.com
5.1 Installation instructions
Storage at high humidity can lead to fogging of the front glass after switch-on, which can affect the
functioning of the unit.
uDo not exceed the following limits:
Temperature Maximum recommended relative humidity
25 °C 75 %
30 °C 72 %
35 °C 70 %
40 °C 67 %
uAvoid back light, scattered light and changing light conditions. Sunlight hitting the lens or the scene
to be monitored may cause interference.
uEnsure mechanical decoupling when installing the unit to prevent the sensor from vibrating.
uAvoid installation in heavily polluting areas of the machine.
Units mounted side by side can interfere with each other when exposed to active lighting
simultaneously.
uEnsure constant external illumination or trigger the units one after the other.
uMake sure that the pressure compensation element on the bottom side of the unit is not covered.

6 Electrical connection
ATTENTION
The unit must be connected by a qualified electrician.
Protection class III (PC III) unit (IEC 61010-2-201 chap. 6.5.2.101.4).
The electrical supply must
- be provided only by PELV circuits (IEC 61010-2-201 chap. 3.111),
- not exceed 35 V DC during operation,
- not exceed 60 V DC in the event of a single fault and
- not exceed the permitted operating voltage of the unit (see data sheet).
Use energy-limited circuits for the electrical supply (IEC 61010-1 chap. 9.4). The energy of
the circuit can be limited at an operating voltage of 24 V by an overcurrent protection
device. The overcurrent protection device must switch off a current of 8.3A in maximum
120s. Observe the specific tripping characteristic. Possible overcurrent protection devices:
- fuse or
- non-adjustable and non-self-reclosing electromechanical device.
Separate the circuit from other, non-energy-limited circuits by at least basic insulation. The
separation of external circuits must comply with IEC61010-2-201, figure 102.
uDisconnect power before connecting the unit.
uFor cable lengths >30m use an additional protection against surge voltages to
IEC61000-4-5.
ATTENTION
The device can be damaged by insufficiently tightened M12 connectors.
wThe IP rating indicated in the data sheet is only guaranteed if the M12 connectors are
firmly screwed.
uFirmly screw the M12 connectors to the device.
For the scope of validity cULus:
Minimum temperature rating of the cable to be connected to the field wiring terminals: 70°C.
Observe when connecting the device:
uUse strain reliefs for cables connected to the device.
uCover the unused sockets with protective caps (E73004). Tightening torque 0.6...0.8 Nm.
If the device is permanently used in wet areas, the nut of the M12 industrial Ethernet connection
cable (e.g. E11898) may corrode.
uUse a connection cable with a high-grade stainless steel nut.
