FATEK PLC to communicate with RS232 Bar Code Reader

FATEK PLC to communicate with RS232 Bar Code Reader

FATEK PLC to communicate with RS232 Bar Code Reader

(OP)
Hello there!

I'm an Electrical Engineer and I want to do an application using a PLC from FATEK. What I want is to communicate my PLC with a Bar Code Reader using the RS232 port. I want it to read the code and my PLC have to store it to be used elsewhere. Is there anyone with practice with this kind of application?

Best regards.

Gustavo

RE: FATEK PLC to communicate with RS232 Bar Code Reader

If your looking for standard code for Asc2 I know that most plc manufacturers have standard code for Asc2 or barcode data. If they dont then not sure about their support level for this type of application for this plc brand.

This is typical data from bar code reader and how i usually setup:
STX beginning asc2 code says here is where barcode info starts.
data inbetween is the barcode info, how you set that up depends on what barcode your looking for which is a ton of formats.
ETX end of barcode info

Most barcode readers have ethernet interfaces so your not stuck with RS232 which is for under 25 feet distance max or use RS422 which is up to 5000 feet.
