Presentation
The Modicon M580 automation platform offers four different types of architectures with local racks or with racks in 
remote drops. These four options are presented on the following pages as architectures A, B, C and D.
The Modicon M580 automation platform offers an I/O architecture solution over local racks, eldbuses and 
Ethernet, connecting the M580 main rack to remote I/O (RIO) drops, installed on a Modicon X80 rack (1), and 
distributed I/O (DIO) devices.
This Modicon M580 solution comprises:
b RIO drops on a Modicon X80 drop
b Ethernet DIO devices
b A choice of three CRA Ethernet drop adapters (standard or high performance) in each Modicon X80 RIO drop
b Two optical repeaters, for single mode or multimode optical ber, on Modicon X80 RIO drop
b A choice of three types of managed dual ring switches (DRS) from the ConneXium offer (2), congurable by 
means of predened conguration les for immediate setup
Different architectures are therefore possible, such as:
b Ethernet RIO architectures with or without ConneXium managed switches (2)
b Architectures with separate or combined Ethernet RIO and Ethernet DIO devices on the same physical 
medium
This solution also includes numerous options and functions as standard, providing:
b High process availability, with the option of connecting Ethernet RIO and Ethernet DIO in a daisy chain loop
b Deterministic data exchanges between the PLC and the Ethernet RIO
b Remote service, with a SERVICE port available on the M580 CPU or Modicon X80 CRA Ethernet drop 
adapters

Typical architecture (3)
(1)  The Modicon X80 range offers common I/O modules which can be used both in Ethernet RIO drops connected in 
Modicon M580 automation platforms.
(2) Supported ConneXium switches: TCSESM083F23F1/063F2CU1/063F2CS1 (see page 2/11).
(3)  This typical architecture representation is a conceptual network diagram and does not represent the actual wiring 
specications. 
Note
b The validated and tested 
architectures are shown in 
the technical documentation 
available on our website 
www.schneider-electric.com.
b The use of switches other 
than those detailed in these 
architecture I/O pages
(pages 2/4 to 2/19) is not 
supported (2).
