Without ConneXium

managed switches

Ethernet RIO architectures
Ethernet RIO without ConneXium managed switches
Simple Ethernet RIO architecture specically for applications requiring discrete I/O,
analog I/O or the 140ERT85410 multifunction input module.
Maximum distance between each rack is 100 m.
Ethernet RIO with ConneXium managed switches
Ethernet RIO architecture specically for applications requiring discrete or analog
I/O. Integration of ConneXium managed switches allows drops to be located
remotely using a ber optic link:
Over long distances (more than 100 m) b
In environments subject to a great deal of interference b
Connecting sites that do not share the same earth ground point where a potential b
difference between the sites may exist.
Each switch also allows the management of a secondary Ethernet RIO ring.
Ethernet RIO and Ethernet DIO devices (2)
Separate Ethernet RIO and Ethernet DIO devices
Conventional architecture with Ethernet RIO and Ethernet DIO devices on two
isolated networks:
The Ethernet RIO are connected to the PLC via the 140CRP31200 Ethernet head b
adaptor (1).
The Ethernet DIO devices are connected via the 140NOE771 b pp or
140NOC77100 Ethernet communication module (2).
Combined Ethernet RIO and Ethernet DIO devices
This architecture has the advantage of being able to combine Ethernet RIO and
Ethernet DIO devices on the same physical network.
It allows a ConneXium managed switch to be connected from the
140CRP31200 Ethernet head adaptor (1). This switch is used for addressing the
Ethernet RIO and the Ethernet DIO devices.
The entire network is connected to the CRP Ethernet head adaptor (1).
A TCSECN3M3M1S4/1S4U Ethernet Interlink cable (3) between the 140CRP31200
Ethernet head adaptor (1) and the 140NOE771pp Ethernet communication module
(2) is used to access the communication module functions.
The Ethernet DIO devices (standalone devices and devices connected in a daisy
chain loop) should be connected directly to a ConneXium managed switch.
For simple architectures without switches, the Ethernet DIO devices can also be
connected directly to the SERVICE ports on the CRP Ethernet head adaptor and
CRA Ethernet drop adaptor.
This architecture features:
Reduced wiring costs b
Deterministic data exchanges between the PLC and the Ethernet RIO b
High availability of Ethernet DIO devices that can be connected in daisy chain b
loop topology (limited to devices compatible with this type of architecture)
Maximum distance between each ConneXium managed switch:
100 m with copper medium b
2 km with multimode ber optic medium b
15 km with single mode ber optic medium b
