I/O architectures
Distributed I/O (DIO)
The Modicon Quantum platform DIO (Distributed I/O) architecture uses the same
I/O modules as a local or remote I/O (RIO) subsystem, and reduces installation costs
by using low-cost twisted pair cables.
Special DIO drop adaptors, with a built-in power supply, are used at each drop. The
Quantum DIO drop adaptor is specifically designed to link I/O modules to the head-
end via a shielded twisted pair cable. DIO drop adaptors (one per drop) also provide
the power supply to the I/O (maximum 3 A), from a 24 V c or 115/230 V a source.
These DIO drops can also be powered by standard 8 A power supply modules. In
this case the 3 A supply built into the drop adaptor is not used.
The DIO architecture can take up to three network heads per CPU and up to 1800 m
per network (using RR85 repeaters). Even greater distances can be achieved using
fiber optic repeaters.
The DIO architecture is based on Modbus Plus technology. Each DIO network can
take 32 nodes over 472 m (with repeaters, 64 nodes over 2000 m). Up to three DIO
networks are permitted, one native to the CPU itself, and the other two by adding
140 NOM 211 p0/212 p0 head-end modules in the local Quantum rack. RIO and
DIO can be combined in the same CPU, for large quantities of I/O.
Products that can be connected to Modbus Plus networks (for example HMI
equipment) can coexist on the DIO network. For example, a programming terminal
can be connected to the DIO network to monitor and troubleshoot a control system
from a remote site, without requiring a separate communication link.
