XTIOT industrial barcode scanners provide stable and standard communication methods for direct connection with PLC, servo systems, sensors, robots, and production line control systems. They are widely used in automated assembly lines, conveyor sorting, and industrial data collection applications.


Supported Communication Interfaces


RS232 / RS485: Standard serial communication for stable data transmission in industrial environments.
TCP/IP Ethernet: High-speed network communication for long-distance and multi-device networking.
Profinet: Standard industrial bus for direct access to Siemens and other mainstream PLC systems.
EtherNet/IP: Compatible with Rockwell and related industrial automation platforms.

IO Trigger & Output: External trigger input and result output for high-speed automated control.


Wiring and Connection Method

Power Connection: Connect to 12V or 5V industrial power supply according to the scanner model.


IO Signal Terminal:
  • Input Trigger: Connect to PLC output or photoelectric sensor to activate scanning.

  • Output Result: High/low level feedback for successful or failed decoding.

    Communication Cable: Use industrial-grade shielded cable to reduce interference.

Communication Configuration
Serial Communication: Set the same baud rate, data bit, stop bit, and parity on both scanner and PLC.
Ethernet Communication: Configure the same network segment IP address for scanner and PLC.
Industrial Bus: Import the device description file and complete node configuration in PLC programming software.

Data Format: Set unified output rules including suffix, separator, and data packet structure.


Data Transmission Mode
ASCII String Output: Directly send barcode data to PLC for processing.
Fixed-Length Data Packet: Standardized format for stable industrial transmission.
With Check Code: Improve reliability in strong-interference environments.

Real-Time Upload: Immediately upload data after successful decoding for high-speed lines.


Typical Application Flow
  1. The sensor or PLC sends a trigger signal to the scanner.

  2. The scanner captures and decodes the barcode automatically.

  3. The scanner outputs scanning result to the PLC.

  4. The scanner sends a level signal to indicate success or failure.

  5. The PLC performs logic control such as sorting, rejecting, or recording.

Supported PLC Brands

Siemens, Rockwell, Mitsubishi, Schneider, Omron, Delta, Inovance and other mainstream brands.


Configuration Tools

XTIOT Config Software: Set communication parameters, IO logic, and data format.
Web Management Interface: Ethernet scanners support browser-based configuration.

Serial Command Set: Used for secondary development and automated integration.


Advantages for Automation Systems

Stable industrial-grade design: Anti-interference, wide voltage input, IP65 protection.
Multiple bus protocols: Plug-and-play with most PLC systems.
Real-time response: Microsecond-level reaction for high-speed production lines.
Easy integration: Clear wiring, complete documentation, and short commissioning time.
