Introduction

Physical Layer

The physical layer contains a single twisted pair of shielded wires. The

 

STB NIB 1010 INTERBUS implements the SUPI 3 (serial universal peripheral

 

interface) ASIC from Phoenix Contact.

Network

 

The INTERBUS network observes a master/slave model with active ring topology,

Topology

having all devices integrated in a closed transmission path. There are three types of

 

bus￿structures in the ring:

 

remote bus—The Advantys STB island (with an STB NIB 1010 INTERBUS NIM

 

at the head) connects to this section. Remote bus characteristics include:

 

 

12.8 km (maximum) network length

 

 

512 possible connections

 

 

400 m (maximum) between devices

 

￿

256 devices (maximum)

 

local bus (not supported)—The local bus ring is used to connect I/O devices in a

 

remote substation enclosure. Local bus characteristics include:

 

 

8 devices (maximum)

 

 

1.5 m (maximum) between devices

 

 

10 m (maximum) network length

 

￿

800 mA (maximum) current

 

sensor loop—The sensor loop is connected directly to sensors and actuators

 

without the use of bridge routers. Sensor loop characteristics include:

 

 

1 unshielded pair (+24 V)

 

￿

32 devices (maximum)

 

 

10 m (maximum) network length

Note: An Advantys STB island with an INTERBUS NIM head can be implemented only as a remote bus node.

Transmission While it is possible to connect INTERBUS devices with a variety of media (fiber

Mediaoptics, SMG, etc.), the STB NIB 1010 NIM only supports networks that are connected with twisted pair copper wiring (RS-485). Network connectors (in and out) are 9-pin SUB-D types. The TDMA transmission method is implemented for transmission rates of 500 kbits/s.
