guillencito Posted November 24, 2004 Report Posted November 24, 2004 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. Quote
mgvol Posted November 24, 2004 Report Posted November 24, 2004 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. Quote
Chris Elston Posted November 25, 2004 Report Posted November 25, 2004 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 Quote
Ken Moore Posted November 25, 2004 Report Posted November 25, 2004 I've used a Banner vision system for the same type of thing. Had to determine label was right color also. Quote
Guest Luciano Vasconcelos Posted November 25, 2004 Report Posted November 25, 2004 Hi, Try to use the following ones : BCL8 supplied by Leuze. ( www.leuze.de ) or another one ( serie 1000/2000 - DS2200 ) from datalogic ( www.datalogic.com ) Another is www.seal.com.br Regards, Luciano Vasconcelos Quote
Andy_P Posted November 25, 2004 Report Posted November 25, 2004 I have also used Microscan barcode readers, specifically MS-911, which has discrete I/O. Andy. http://www.microscan.com Quote
Guest Piotr Posted November 26, 2004 Report Posted November 26, 2004 Sick barcode readers from CLV430 series have AFAIR 2 programmable outputs. Quote
Crossbow Posted November 29, 2004 Report Posted November 29, 2004 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? Quote
