The DataMan Industrial Protocols Manual provides comprehensive guidance for integrating Cognex DataMan barcode readers into industrial automation systems using a wide range of Ethernet-based protocols. It describes how to enable, configure, and operate protocols such as EtherNet/IP, PROFINET, SLMP, CC‑Link IE Field Basic, ModbusTCP, and EtherCAT.

The manual explains reader object models, assembly layouts, control/status signaling, SoftEvents, DMCC command execution, result transfer, buffering, and fragmentation for long codes. It also includes protocol‑specific setup procedures and PLC programming examples for Rockwell, Siemens, Mitsubishi, Wago, and Beckhoff. A dedicated section covers wireless DataMan considerations, including BaseStation behavior, offline buffering, and limitations. Overall, it serves as a full reference for reliable triggering, communication, and result handling in automated production environments.
