4.4 Switching output
[Übersetzung ist nicht mehr aktuell]
Switching output OUT1 is configurable. The output is not switched by default.
The configuration can be done individually for each application using the ifm Vision Assistant software.
The table below shows the standard configuration.

Tab. 3: Switching output standard configuration
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 contour and blob (e.g. object/model
found, object/model matches the reference, object/model 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.

Observe the safety instructions for photobiological safety. (
The internal and external lighting is switched on 500 µs before the image is taken. Switching on
prematurely does not affect the brightness of the captured image.

Example: With an integration time of 100 µs, the lighting is switched on for 600 µs.
