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.
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.
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)
•SLC 500 processor I/O data table limit (4,096 input and output bits)
•processor memory to support the application (SLC processor dependent)
