The Remote I/O (RIO) scanner, Catalog Number 1747-SN, is the
remote I/O scanner for the SLC 500. It enables communication
between an SLC processor (SLC 5/02
located (3,048 meters [10,000 feet] maximum) 1746 I/O chassis and
other RIO compatible Allen-Bradley operator interface and control
devices. The 1747-SN scanner communicates with remotely located
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. The scanner can reside in any
slot of the local SLC chassis except for slot 0.
RIO Scanner
(Master of the
RIO Link)
The scanner transfers input and
output data between itself and all
configured network devices over
twisted pair cable. Note that the
end to end length of the cable can be
a maximum of 3,048 meters (10,000
feet).
