Introduction (continued)
Advantages
Flexibility, availability of combinations and deterministic operation
Flexibility of Ethernet topologies provides many different options to meet the b
needs of numerous applications.
Ability to combine Ethernet RIO and DIO devices on the same medium enables: b
Reduced wiring costs
v
Up to 31 Ethernet RIO drops and 128 Ethernet DIO devices
v
Deterministic nature of data exchanges between the PLC and the Ethernet RIO b
allows the system response time to be calculated for the Ethernet RIO, regardless
of the number of Ethernet DIO devices.
Increased process performance and availability
High performance levels exceeding the current limits for Modicon b
™
Quantum
™
architectures (S908 network) with 400 input words and 400 output words per drop
(instead of 64 input words and 64 output words for the S908 architecture)
High overall process availability in Hot Standby architectures with: b
Primary ring and secondary ring topologies using the Ethernet ports on the
v
CRP Ethernet head adaptor and CRA Ethernet drop adaptor
RSTP (Rapid Spanning Tree Protocol) for the primary ring or secondary ring,
v
enabling a ring to self-heal in less than 50 ms if there is a cable break or a
module becomes inoperative
Remote debugging
CRP Ethernet head adaptors and CRA Ethernet drop adaptors have 3 or 4
connection ports, depending on the module:
2 DEVICE NETWORK ports for daisy chain loop connection of Ethernet RIO b
1 SERVICE port supporting a rate of 5 Mbps for connecting Ethernet DIO devices, b
up to a maximum of 20 Mbps for Ethernet DIO ports:
Local HMI (Magelis
v
™
terminal, etc.) (1)
One or more Ethernet DIO devices
v
PC with Unity Pro software
v
(2) for debugging an application remotely
Network diagnostics with the ConneXview
v
™
or HiVision software, or other
network analysis tools (Port Mirroring, etc.)

Online conguration modication with the CCOTF function
The CCOTF (Change Conguration On The Fly) function enables I/O modules to be
added to or removed from a Quantum PLC conguration in RUN mode.
It also enables the conguration parameters of pre-existing and new I/O modules to
be modied online.
These changes are possible on the Quantum local rack and on RIO drops (Ethernet
or S908 networks).
This CCOTF function avoids interruptions to processes and helps reduce
production costs.
Compatibility with references in the Quantum catalog
Quantum Ethernet I/O offer is fully compatible with the references in the Quantum
offer (CPUs, power supply, I/O modules, racks).
This compatibility simplies:
Implementation of Ethernet I/O architectures b
Migration from a S908 network architecture to a Quantum Ethernet I/O b
architecture
Rack Viewer function
Rack Viewer function provides access to Ethernet RIO data via a web browser.
Function requires the 140NOE77111 Ethernet communication module.
Predened congurations for ConneXium managed switches
Use of ConneXium managed switches specically for Quantum Ethernet I/O
architectures is simplied using 7 predened conguration les (included on the
Unity
™
Pro u V6.0 DVD). These congurations are optimized to meet the
requirements of the majority of Ethernet architectures (see page 17).
(1) Please refer to the “Human-Machine Interfaces” catalog.
(2) Requires Unity Pro Extra Large software u V6.0.
