Advantys STB Islands of Automation
System
Definition
Advantys STB is an open, modular distributed I/O system designed for the machine
industry, with a migration path to the process industry. Modular I/O and power
distribution devices reside on the island bus. The island functions as a node on a
fieldbus control network and communicates with the fieldbus master controller.
Open Fieldbus
Choices
An island can function as a node on the following open industry-standard fieldbus
networks:
Profibus DP
DeviceNet
Ethernet
CANopen
Fipio
Modbus Plus
INTERBUS
A network interface module (NIM) resides in the first position of the island bus
(leftmost on the physical setup). The NIM acts as the gateway between the island
and the fieldbus, facilitating data exchange between the fieldbus master and the I/O
modules on the island. It is the only module on the island that is fieldbus-
dependent—a different type of NIM module is available for each fieldbus. The rest
of the I/O and power distribution modules (PDMs) on the island bus function exactly
the same, regardless of the fieldbus on which the island resides. You have the
advantage of being able to select I/O modules and establish island functionality
independent of the fieldbus on which it will operate.
I/O Modules on
the Island
In your application, you can combine a comprehensive set of I/O modules
specifically designed for the island with island-compliant devices from other
Schneider product catalogs (called preferred modules). Standard CANopen devices
can also be included in your combination of I/O devices.
Granularity Advantys STB I/O modules are designed to be small, economical devices that
provide you with just enough input and output channels to satisfy your application
needs. Specific types of I/O modules are available with two or more channels. You
can select exactly the amount of I/O you need and you do not have to pay for
channels that you don’t need.
