To meet the needs of machine manufacturers and users, automation architectures
have been decentralized while delivering performance close to that of centralized
systems.
Architectures based around islands installed as close to the machine as possible
reduce the time and cost of wiring for sensors and actuators, while increasing
system availability.
The Modicon STB distributed I/O system is an open, modular input/output system
and makes it possible to design industrial automation islands managed by a master
controller via a bus or communication network.
These islands can be used to connect:
TeSys U or TeSys T motor starters
Altivar variable speed drives
FTB IP 67 distributed I/O
OsiSense rotary encoders
Magelis HMI terminals
Approved third-party products via the CANopen bus: Bosch, Festo,
Parker valves, Balluff linear encoders, etc. (1)
Advantys software guides users through the design phase, start-up, and even
maintenance of the system. This single software package covers the Modicon STB,
OTB, FTB, and FTM ranges.
The island components are electronic modules mounted on one or more DIN rails.
These clusters of modules, known as segments, carry a bus from beginning to end of
each island. The island bus provides power distribution, signal sensing, and power
management to all compatible modules, in the form of a wiring management system.
The Modicon STB I/O family can be divided into 2 groups of modules:
Basic modules: A set of low-cost modules, with simplied operating modes.
Standard modules: An extended offer of I/O modules, with additional functions:
congurable parameters, extended operating modes.
The basic range comprises:
PDM power distribution modules (24 V and 115/230 V )
I/O modules:
Digital I/O (24 V )
Analog I/O (10-bit resolution).
The standard range comprises:
NIM modules: network interfaces
PDM power distribution modules (24 V and 115/230 V )
I/O modules:
Digital I/O (24 V and 115/230 V )
Analog I/O (10, 12, and 16-bit resolution)
Relay outputs (24 V coil and 24 V or 115/230 V contact)
Application-specic module: counter module, HART multiplexer
Dedicated module: for TeSys U and TeSys Quickt applications
EOS end of segment and BOS beginning of segment modules.

Standard and basic modules can be combined on the same island. Combining them
in this way allows a wide range of functions as shown in the table on page 15.
The sensors and actuators are connected to the I/O modules via removable
screw-type or spring-type terminals (2)
Standard Modicon STB I/O modules are hot-swappable, provided the network
interface modules are also standard type.
Modicon STB distributed I/O islands have a protection rating of IP 20. For
installations in production workshops, they must be incorporated in protective
casings with at least an IP 54 rating (in compliance with IEC 60950 or NEMA 250).
