Modicon STB distributed I/O
solution
Open and modular system
Hot swapping
When a module on the standard type Modicon STB island is unplugged under power,
the behaviour of the other modules depends on the parameter settings of standard
type I/O modules :
 Mandatory or optional module
 Congured fallback type per channel.
Swapping a module Behaviour of the other modules (1)
Basic input The other outputs remain operational
Standard input optional The other outputs remain operational (1)
Standard input mandatory Fallback of other outputs according to conguration (1)(2)

They are designed for use in industrial environments of pollution class 2, in
applications of overvoltage category II (as dened in publication IEC 60664-1) and at
altitudes of up to 2000 m, without reduction in load.
Protection enhanced with a coating is provided on request, for use in harsh industrial
environments (see page 117).
