Bar code reader with discrete outputs

8 posts in this topic

Hi, all I have a question: Did you know about some barcode reader with discrete outputs? Let me explain you: I have a NAIs PLC which need to know if a number is right. This number is a barcode printed in a label, and this number is necessary to start the process. So, i know that NAIs didn't have the capability to keep string registers entered by serial port (like entered by a barcode reader). So I think about a barcode wich I can program the valid codes and this reader coud set an output if the codes are right. What do you think about this? I'll be very grateful by you comments or suggestions.

In theory, this should work (although I am shocked at a PLC that won't take strings over the com port). Take a look at SICK barcode readers; they may have a model w/on-board I/O.

I've used a Keyence Series Interface Unit to do what you need. Basically I trained the bar code reader to read a "bar code label" When it reads the bar code that matches, it turns on an OUTPUT for me. Simple, fast, effective. When a label wasn't present, it did not output. Meaning it didn't read it, or was missing a label. http://www.keyence.com/products/barcode/ba..._features_1.php http://www.keyence.com/products/barcode/ba...cations_1_1.php I used a Keyence bar code reader too... http://www.keyence.com/products/barcode/ba..._features_1.php

I've used a Banner vision system for the same type of thing. Had to determine label was right color also.

I have also used Microscan barcode readers, specifically MS-911, which has discrete I/O. Andy. http://www.microscan.com

Sick barcode readers from CLV430 series have AFAIR 2 programmable outputs.

I've used the Accusort Model 20 (Omron rebranded as V550-A20) with discrete outputs, or with ASCII strings into the PLC. Are you sure you can't use an ASCII command in the PLC to receive te info you need from the serial of the bar code reader?
