For sensitive processes, requiring an I/O control takeover time within the region of
the PLC scan time, an I/O architecture based on RIO (Remote I/O) native topology
should be chosen by default.
The scanning of RIO drops is synchronous with the CPU scan time. As a result, the
RIO remote I/O architecture provides a smooth CPU switchover with regard to the
outputs, i.e. with no disturbance.
RIO I/O drops, consisting of Quantum modules, are recognized and configured from
the Unity Pro
A splitter box
drops
The line impedances
necessary to disconnect one of the I/O CPUs. The optional grounding terminals
60 0545 000 are used to maintain the grounding of the coaxial cable in these
conditions.
The availability of this I/O system can be reinforced by using a dual-medium I/O
wiring system. It is possible to transpose these I/O drops on a (single or dual)
optical ring, using optical repeaters.
Note: For items 1, 2, …15, see pages 3/21 to 3/23.
The components are available in kits.
