Overview of DV-90 Functions
Automated Product Selection at an Assembly Workstation
By reading the barcode attached to an assembly instruction sheet or a product in a high-mix low-
volume production line, the lamp on the shelf which contains the part to be assembled illuminates.
By assembling the part stored on the illuminated shelf, assembly errors can be reduced.
Use the “Normal Verification” function. Refer to 4-4
Up to 900 presets be registered beforehand in the DV-90 as master data. The data read with the bar-
code reader is compared with the master data, and the corresponding preset number is output in par-
allel transmission.
In the above figure, the barcode on the assembly instruction sheet is preset in the DV-90. By con-
necting the parallel output after verification to a device such as a PLC, the corresponding lamp on
the part shelf illuminates, thus preventing assembly errors.
Other uses
• Commanding operations to robots
By connecting the parallel output to a PLC for controlling a robot, the DV-90 can command the
robot to perform specified operations.
• Switching the setting values of devices
The parallel output allows the setting values of the connected devices such as a weight checker to
be changed automatically.
Note
The figure above is an example using a handheld reader. A fixed type reader can also be
used.
