The Allen-Bradley 1747-SN SLC 500 Remote I/O Scanner Module 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 10,000ft. 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. The user can adjust the size of the scanner image files during configuration of the SLC system so that the scanner only transfers the discrete I/O data required by the 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. 

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 he application (SLC processor dependent)
