The 1747-SN is a Remote I/O Scanner module for the Allen-Bradley SLC 500 platform, enabling communication between an SLC processor and remotely located RIO-compatible devices.
Single-master network controller
Daisy-chain topology utilizing
Twisted-pair cable communication
The Remote I/O (RIO) Scanner, 1747-SN, enables communication between an SLC processor and remotely located 1746 I/O chassis and other RIO-compatible Allen-Bradley operator interface and control devices. The 1747-SN scanner communicates with remote devices using the A-B Remote I/O link. The RIO link consists of a single master (scanner) and multiple slaves (adapters). Communication between devices occurs over twisted-pair cable with the devices daisy-chained together. Maximum distance for remote communication is 3,048m (10,000 ft.). The scanner is compatible with any standard RIO adapter device.
The SLC processor transfers a maximum of 4 logical racks (32 input and 32 output image words) of discrete remote I/O data into the SLC input and output image files. You can adjust the size of the scanner image files during configuration of your SLC system so that the scanner only transfers the discrete I/O data required by your application program. The 1747-SN Series B or later RIO Scanner can be configured to transfer up to 64 words of data to a remote device via block transfer.

When using 1747-SN you follow the remote I/O network physical rules and software configurations. The key involves installing terminating resistors at both ends and using dedicated blue hose cables within the baud rate length limits. Also you need to correctly set the main rack G-File and remote adapter dip switches to avoid address conflicts.
It supports a maximum network distance of 3,048 meters (10,000 feet), connecting to 1746 I/O chassis, operator interfaces, and other control equipment.
What is the maximum length supported by the RIO protocol?
The 1747-SN may be implemented up to a physical distance of 3050 meters or 10,000 feet at 57.6K baud.
How many communication ports does the 1747-SN have?
The 1747-SN has one dedicated 3-pin Remote I/O (RIO) communication port.
What is the appropriate communication cable used by the 1747-SN?
The 1747-SN uses the Belden 9463 (Blue Hose) shielded cable in a daisy-chain topology with terminating resistors.
