Calling up the web front end

▶ Enter the IP address of the device 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.
• The settings are made via the ifm Vision Assistant software.

- 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 ( → 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.

Fig. 1: Ready signal ("Ready for trigger")

Example: A diffuse reflection sensor as an external trigger source triggers the unit on a positive edge ( t_A = evaluation time).

4.3.2 Internal debouncing

Fig. 2: 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 ifm Vision Assistant. The table below shows the standard configuration.

Output	Standard	External illumination	Process interface
OUT1	For applications via ifm Vision Assistant:Ready signal (“Ready for trigger”)0: unit busy1: unit ready for trigger signal		Selectable via command
	When using the teach button:evaluation successful (pass/fail)
OUT2	For applications via ifm Vision Assistant:code evaluation0: code evaluation not successful1: code evaluation successful	Trigger output
	When using the teach button:OUT2 not used

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" ( → 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 ifm Vision Assistant software.

Fig. 3: Illumination LEDs

- O2I5x0, O2I5x2, O2I5x4: red light (617 nm) and integrated polarisation filter
