Techniques barcode scanning module and PLC industrial control equipment connected
Industrial control PLC more and more appear in the production line, automatic operation lines. These goods are produced on the assembly line with a bar code, there are many scenarios require the PLC controller operating barcode scanning module to read the bar code on the provider, and then determine the bar code data to the next step.
Today we'll talk about the PLC coupler precautions and bar code scanning module:
Communication interfaces are serial TTL level one barcode scanning module, which is more associated with PLC controller RS485 or RS232 interface, you need level interface converter.
2 RS232 transmission distance is limited, if the bar code scanning module and farther away from the PLC, it is recommended to convert to RS485 remote communication. This is not easy to lose data.
The default baud rate is usually 3 barcode scanning module is 9600, so when you try to join 9600 recommendation from the beginning. Communication speed is not usually transferred to a relatively high, prone to interference during data transmission.
4 bar code scanning module to scan, may be attached carriage return, line feed, etc. behind the bar code can be associated on and off by setting the scan code setting.
5 If the conditions recommended barcode scanner module and the PLC coupling cable should be shielded to ensure data transmission without errors.
6 yards scanning module data is sent to the PLC barcode contents ASCII codes in the PLC process please pay attention to distinguish whether the hexadecimal value HEX or ASCII code directly, different barcode scanning module is not the same.
7 Some bar code scanning module with an Ethernet or other interface, please note that the definition of the PLC communication protocol to use.

LV3080 2D:TTL232 Interface; barcode scanner module
Production Introduction:
LV3080 is the world's smallest 2D scan engine, armed with a computerized image recognition system, bringing about a new era of 2D barcode scan engines.The LV3080, a compact, lightweight engine fits easily into even the most space-constrained equipments such as data collectors, meter readers, ticket validators and PDAs.The LV3080 also features an industrial grade sensor with no moving parts to wear out and the product is carefully designed based on years of industry knowledge for easy integration into OEM devices.
Product Features:
1) 2D barcode decoder chip
The engine armed with the state-of-the-art 2D barcode demonstrates unprecedented reading performance.
2) Two-in-one design
Seamless integration of CMOS image sensor and decoder board makes the engine small, lightweight and easy for integration.
3) High Performance & Ultra-Low Power Consumption
The engine can read most 1D and 2D barcodes with a power consumption only one fourth that of a traditional engine.
4) All-Round Scanning Capability
It can read barcodes on virtually any medium - paper, plastic cards, mobile phones and LCD displays.
