Title: Simple Bar code reading required
Post by: navair67 on April 16, 2011, 11:00:56 AM

Looking to put together a simple bar code reader that when scanned it reads the remaining weights to complete and loads them to "V" memory so then I can send data to a HMI.

All the logic is done,im using a D06.I just dont know how to get a bar code reader to read data back to the PLC, Hardware and both Bar code reader types would be helpful and any I/O card that would be needed would help too.

Cheers

Did you get anywhere with your request in February of 2008?

Exactly which CPU are you using?

reads the remaining weights to complete

This is information in the barcode?

I've always used a BASIC module with a serial link to the barcode reader. I do any extracting of values which may be buried in the middle of the barcode response in the BASIC module then supply the result to appropriate V memory registers.

The current barcode readers we are using are from Microscan:

Im using a D06-AR,but dont know what card to buy to read the bar code reader.
Im printing a barcode with only really 4 pieces of information that the PLC has to read (recipe weights).
Then I was looking to extract that to a location and allow the PLC to take over the function.

When you say BASIC module what card is that in the catalog?

BTW no response back in 08 :(

It's the F0-CP128. It is very flexible and communicates to the D0-06 CPU.

Thanks a bunch. I will be ordering the card this week and the HS-1 from Microscan (and probably be posting again to find out how to right some code)This is a bit beyond my knowledge ???.

Cheers
and thanks again
