The Modicon Quantum Automation Series provides a flexible architecture that
ensures a cost-effective and high performance control solution, regardless of the
configuration. From centralized systems to highly distributed systems to networked
distributed control schemes, Quantum provides the right solution.
Quantum I/O can be used in three major architectures to meet control system
requirements:
b Local I/O.
b Remote I/O (RIO).
b Distributed I/O (DIO).
