Retrying While External Trigger Is Input

Reading is performed until successful, as long as

an external level trigger is input.

Retrying While Changing the Shutter Speed

Reading is performed for the same scene while changing the exposure time in stages.

Scene 1

When reading DPM codes, inconsistencies in

printing conditions can result in NGs if reading

is performed with only one set of reading set-

tings. The FQ2 allows you to register up to 32

sets of reading conditions as scenes and retry

reading while changing the scenes in order.

The system automatically determines the

scenes with the highest usage rates and

changes the order to start with them to flexibly

handle changes in reading conditions. Of

course you can specify a fixed order if required.

Smooths the image.

Smooth

For white codes, increases the cell size.

Effective for reading codes with cell spreading.

Dilate

For white codes, reduces the cell size.

Effective for reading separated dot codes.

Erosion

Removes noise.

Median

Types of Filtering

You can apply up to three of the four unique filters developed by

OMRON in the desired order to remove printing irregularities and

noise, in order to achieve a stable reading.

Retry function

Code Readers must be able to read codes even for poor printing conditions. You can automatically retry reading while changing the exposure time

and other reading conditions, even for changing workpieces or environments, to enable a stable reading.

Combining Filtering

Erosion and dilation can be combined to connect dots without chang-

ing the dot thickness.

・Print Quality Grading Function

The function to evaluate the quality of a 2D code (DataMatrix) enables an in-line check of the relative quality change and the pa-

rameter where the change occurred.

Note This function evaluates relative change in code quality and does not give absolute grading

The FQ2-S4 with sensor version 2.20 or later provides this function.
