The document follows the logical mainline of "safety specifications → system positioning → hardware configuration → installation and operation → fault handling", covering the entire process of module configuration from early stage to later stage maintenance. The applicable product is the 1747-DCM direct communication module, which serves as the communication interface module for SLC 500 series controllers (including extended chassis or modular controllers). It is connected to higher-level Allen Bradley controllers (such as PLC-2/3/5, SLC with RIO scanner) through RIO (Remote I/O) links to achieve data transmission between distributed processors, and is suitable for multi controller collaboration scenarios in industrial automation (such as multi area data exchange in production lines and remote device monitoring).
