What Is Advantys STB?
Introduction Advantys STB is an assembly of distributed I/O, power, and other modules that
function together as an island node on an open fieldbus network. Advantys STB
delivers a highly modular and versatile slice I/O solution for the manufacturing
industry, with a migration path to the process industry.
Island Bus I/O A basic Advantys STB island can support up to 12 Advantys STB I/O modules. The
only I/O devices that may be used in the basic segment are Advantys STB modules;
preferred modules, standard CANopen devices and Advantys STB extension
modules are not supported.
The Basic
Segment
STB I/O modules may be interconnected in a group called the basic segment. The
basic NIM is the first module in this segment. The basic segment must contain at
least one Advantys STB I/O module and can support as many as 12 addressable
Advantys STB modules, drawing a current load of up to 1.2 A. The segment must
also contain one or more PDMs, which distribute field power to the I/O modules. The
basic segment must be terminated by a 120 termination plate, which ships with
the NIM.
