DANGER D’EXPLOSION cs WARNING Publication 1747-IN060D-EN-P - November 2002 4 Remote I/O Scanner Overview 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. m bi a. c n 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. Refer to publication 1747-6.6, Remote I/O Scanner User Manual, for information on configuration, programming, and block transfers. o@ ca The SLC 500™ processor (SLC 5/02 or higher) supports multiple scanners in its local I/O chassis. The maximum number is dependent on the following: • backplane power requirements (power supply dependent) cs pr • SLC 500 processor I/O data table limit (4,096 input and output bits) pl cd • processor memory to support the application (SLC processor dependent) SLC 5/02 or later processor RIO Scanner (Master of the RIO Link) 1747-ASB Module (Adapter/Slave) Remote Chassis Remote Expansion Chassis Local SLC Chassis Dataliner™ Message Display (Adapter/Slave) PanelView™ Operator Terminal (Adapter/Slave) Publication 1747-IN060D-EN-P - November 2002 Redi PANEL™ (Adapter/Slave) Remote I/O Scanner 5 Hardware Features The figure below shows the scanner’s features.

Publication 1747-IN060D-EN-P - November 2002 10 Remote I/O Scanner RIO Link Wiring The scanner is connected to other devices on the RIO link in a daisy-chain (serial) configuration. There are no restrictions governing the space between each device, provided the maximum cable distance (Belden 9463) is not exceeded. A 1/2 watt terminating resistor (included with the module) must be attached across line 1 and line 2 of the connectors at each end (scanner and last physical device) of the RIO link. The size of the resistor depends on the baud rate and extended node capability, as shown in the table below. Note: To use extended node, all devices on the RIO link must support it.
