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.

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:

0: unit busy
1: unit ready for trigger signal

When using the teach button:

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.
