I/O architectures
Remote I/O (RIO)
For applications that require remotely mounted I/O drops, a higher I/O capacity,
and/or connectivity to existing Modicon I/O installations, Quantum provides a remote
I/O (RIO) architecture solution.
Based on the S908 remote I/O network technology, this network is compatible with
existing Modicon I/O installations, including those with 800 and 200 series I/O
modules and Sy/Max I/O. Retrofit installations can therefore incorporate an I/O
installed base to reduce installation costs.
The RIO architecture uses coaxial cabling, and provides long distance capability up
to 4572 km with a CATV cable, or longer with an optional fiber optic cable. It is a
high-performance network, operating at 1.544 Mbps, providing a high I/O data
throughput.
The RIO cabling system consists of a linear trunk cable, with line taps and drop
cables for connection to each remote drop.
Up to 31 remote drops can be configured. Each drop can support up to 128 I/O
words (64 input words/64 output words).
The segment scheduler mechanism increases the performance of the RIO network
by interleaving I/O scanning and execution of the program.
The segment scheduler breaks the application program into logical segments, then
co-ordinates the scanning of the inputs and the updating of the outputs in
conjunction with the execution of the program associated with the segment. The
inputs are read before the program is processed and the outputs are written after the
program is processed. This avoids having to wait for an entire scan before the
outputs are set, thus giving a faster system response time. An RIO architecture does
not therefore reduce system performance.
For most systems, throughput of local or remote I/O can be estimated at no less than
two times scan (with 24 V c I/O modules). Analog values and words are updated
automatically, as fast as discrete I/O, with no user programming.
Quantum is compatible with 800 and 200 series I/O that are earlier generation
products. Using the same RIO head-end interface, 800 series I/O are connected via
J890, J892, P890 or P892 RIO adaptors, and 200 series I/O are connected via
P453/J290 and P451/J291 RIO adaptors.
Other standard components are also compatible with this system, including
MA 0185 100 network T-connectors and MA 0186 100 splitter boxes. The Quantum
remote I/O system also takes Sy/Max I/O drops.
To help ensure a valid configuration, add together the consumptions (in mA) of the
modules in the rack, for each drop, and check that the total is less than the power
available with the selected power supply.
