4.4 Switching outputs
Switching outputs OUT1...OUT5 are configurable. If an external illumination is used, OUT5 serves as
a trigger output.
The configuration can be done individually for each application using the ifm Vision Assistant software.
The table below shows the standard configuration.
Pin Signal Standard configuration
4 OUT5 Trigger output in case of external illumination
5 OUT3 Ready signal (“Ready for trigger”)
0: device busy
1: device ready for trigger signal
6 OUT4 Application results “all models found”
0: not successful
1: successful
7 OUT1 / IN1 Not used
8 OUT2 / IN2 Not used
Tab. 3: 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 contour and blob (e.g. object/model
found, object/model matches the reference, object/model outside the threshold level, etc.).
4.5 Switching inputs
The switching inputs provide the functions of static and pulse-controlled application switching.

4.5.1 Static application switching
Up to 32 different applications can be stored in the unit. With the corresponding configuration the first
4 applications can be selected via the two switching inputs IN1 and IN2.
IN1 IN2 ID number application
0 0 1
1 0 2
0 1 3
1 1 4
