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.
Advantys STB lets you design an island of distributed I/O where the I/O modules can
be installed as close as possible to the mechanical field devices that they control.
This integrated concept is known as mechatronics.
Island Bus I/O An Advantys STB island can support as many as 32 I/O modules. These modules
may be Advantys STB I/O modules, preferred modules, and standard CANopen
devices.
The Primary
Segment STB I/O modules on an island may be interconnected in groups called segments.
Every island has at least one segment, called the primary segment—it is always the
first segment on the island bus. The NIM is the first module in the primary segment.
The primary segment must contain at least one Advantys STB I/O module and can
support an I/O load of up to 1.2 A. The segment also contains one or more power
distribution modules (PDMs), which distribute field power to the I/O modules.
