I am trying to use a fixed Miniscan Ms4404 barcode scanner.

[Joe Tagarisa]

I am trying to use a fixed Miniscan Ms4404 barcode
scanner. In such a way that when a part passes through, it will scan
automatically without manually triggering the barcode scanner. Moreover is
there a way to use this scanner communicate with Slc5/03 Processor?.. basically
to cut it short i need a basic idea on how to setup this entire project. Your
input and suggestions will be greatfully appreciated.

Thanks

Joe

Do you have a means of detecting when the part is in position to be scanned, such as a proximity switch, or a camera, or some sort of load sensor? When you say the part passes through are you saying the part is continually in motion? How fast is it? If it's too fast you may not be able to detect the part being in position and triggering the scanner under software-based control.

as for the question regarding communicating with the Slc5/03 processor, this is a vague question. What's the processor doing? What kind of communication are you referring to? If you have a processor in there, what is the LabVIEW-based app doing?

The project is on the design stage, but the idea is to test for pressure decay in Automotive parts. Here is a scenario.

1.  All the parts to be tested are barcoded for identification.

2. The testing station has a plate that moves in and out to load and unload the parts to be tested. And by the testing table, a Miniscan MS4404 is fixed to read off the barcode.

3.  There will be two proximity switches that detects the part present.

4.  As soon as the part is present it should stay for the entire test which should last for about 10sec at least. Simultaneously the scanner should be triggered.

5.  Now since I am goin to use the MS4404 miniscan, my reseach tells me this miniscan and does not have trigger button, but I understand somewhere out there it can be triggered automatically,Software based, as soon as the part

      is within its range. So that I will be able to communicates with scanner to enable. disable, beep, etc.

6. I need a way to decode the scanned data and store it my data base for passed and failed tests. i guesse this where the PLC and LAbView come into picture.

If there is a way to bypass PLC and cheaper way, I will welcome all the suggestions.

Thank you

According to the manual, the scanner has a serial(RS-232) interface that you would just read with LabVIEW and a VISA function. Don't understand the reference to a PLC.
