Features and Capabilities

The 1747-SN acts as the scanner on the RIO network, continuously exchanging I/O status, diagnostic information, and control data. It supports long-distance communication up to 3048 meters, allowing flexible plant-wide integration.

The module provides robust industrial-grade reliability with wide temperature tolerance and flash memory backup. Its single communication port simplifies setup while maintaining high-speed transfer rates between PLCs and connected devices.

Applications

The 1747-SN is commonly used to integrate:

• PanelView HMIs for operator visualization

• Message displays for production data monitoring

• Remote SLC500 controllers for distributed control

• Third-party gateways or converters for cross-protocol communication

Design Notes

The module fits standard SLC 500 chassis slots and consumes 600 mA at 5V, ensuring efficient power usage. When used with Belden 9463 cable, it delivers reliable and interference-free communication across long industrial networks.
