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 | 
 | 
| STB I/O modules may be interconnected in a group called the basic segment. The | |
| Segment | 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 Ω termination plate, which ships with | 
| 
 | the NIM. |
