Description of Operation
Basics
The image recorder of the MultiSight is a CCD chip with a resolution of 640 x 480 pixels. Evaluation is based on 320 x 240 scanning
points. The sensor is designed for inspection and cannot provide measurement information. To operate the MultiSight, at least one
virtual detector must be configured by designating a Region of Interest and teaching a sample image (see screen shot on page 20).
This virtual detector is stored in a non-volatile flash memory on the sensor and is re-activated for standalone operation after
switching off and on. Standalone operation is, therefore, possible with or without PC or PLC.
Evaluation Method
During operation, the MultiSight continuously compares the pattern of the detected image with that of the reference image. The
pixel grey-scale values of the sample are analyzed and a level of conformity to the original sample is determined. If this level falls
within the user adjustable threshold settings, the sensor turns the PNP output ON or OFF (i.e., the part passes or fails the inspection).
The EtherNet/IP connection is capable of communicating additional data about the inspection.
