Introduction
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 i sland c an s upport u p to 12 Ad vantys STB I/O modules. The
only I/O devices that may be used in the basic segm ent are Advantys STB modul es;
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 AdvantysSTB 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 mo re PDMs, which d istribute field pow er to the I/O module s. The
basic segment must be terminated by a 120Ω termination plate, which ships with
the NIM.

Introduction
What Is a Network Interface Module?
Purpose An island of STB I/O modules requires a network interface module (NIM) in the
leftmost location of the basic island. Physically , the NIM is the first (leftmost) mod ule
on the island bus. Functionally, it is the gateway to the island bus—all
communications to and from the island bus pass through the N IM. The NIM also h as
an integrated power supply that provides logic power to the island modules.
The Fieldbus
Network
An island bus is a node of dis tribute d I/O o n an op en f ieldbu s netwo rk, a nd the NIM
is the island’s interface to that network. The NIM supports data transfers over the
fieldbus network between the islan d and the fie ldbus master.
The physical design of the NIM makes it compatible with both an Advantys STB
island and your specific fieldbus master. Whereas the fieldbus connector on each
NIM type may differ, the loc ation on the module front panel is essen tially the same .
Other NIM conne ctors, such as the pow er s up ply i nte rfac e, a re identical for all N IM
types.
Communications
Roles The NIM manages the exchange of input and output data between the island and
the fieldbus master. Input data, st ore d i n nat ive i sl and bus format, is co nv erte d to a
fieldbus-specific format that can be read by the fiel dbus mas ter. Outpu t data writt en
to the NIM by the m aster is sent acro ss the i sland bu s to upd ate the ou tput modu les
and is automatically reformatted.
Integrated Power
Supply
The NIM’s built-in 24-to-5 VDC power supply provides logic power to the I/O
modules on the basic segment of the island bus. The power supply requires a
24 VDC external power source. It converts the 24 VDC to 5 V of logic power,
providing 1.2 A of current to the island. Individual STB I/O modules in an island
segment generally draw a current load of between 50 and 90 mA. (Consult the
Advantys STB Hardware Components Reference Guide [890 USE 172] for a
particular module’s specifications.)
A basic NIM supports up to 12 Advantys STB I/O modules.

About INTERBUS
Introduction IN TERBUS imple ments a maste r/slave net work model. It c an communic ate with up
to 512 nodes over a dist anc e o f 12.8 km , an d ca n read 1024 inputs and wri t e 10 24
outputs in 4 ms.
Each network slave has an in connector for receiving data a nd an out connector for
transmitting data on the ring. The last device automatically closes and terminates
the network ring; sometimes this last device has no out connector.
Components of a simplified INTERBUS network are shown below:

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
Topology
Transmission
Media
The INTERBUS network observes a master/slave model with active ring topology,
having all device s integrated in a closed tran smission path. There are thre e types of
bus structures in the ring:
l
remote bus—The AdvantysSTB island (with an STB NIB 1010 INTER BU S NIM
at the head) connects to this section. Remote bus characteristics include:
l
12.8 km (maximum) network length
l
512 possible connections
l
400 m (maximum) between dev ic es
l
256 devices (maximum)
l
local bus (not supported)—The local bus ring is used to conne ct I/O d evic es in a
remote substation enclosure. Local bus characteristics include:
l
8 devices (maximum)
l
1.5 m (maximum) between de vices
l
10 m (maximum) network length
l
800 mA (maximum) current
l
sensor loop—The sensor loop is connected directly to sensors and actuators
without the use of bridge routers. Sensor loop characteristics include:
l
1 unshielded pair (+24 V)
l
32 devices (maximum)
l
10 m (maximum) network length
Note: An Adv antys STB islan d with an INTERBUS NIM head can be implemente d
only as a remote bus node.
While it is possible to connect INTERBUS devices with a variety of media (fiber
optics, 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.

Introduction
Node
Addressing
The INTERBUS master device is self-configuring because INTERBUS slave
devices are auto-addressed according to their sequence in a serial ring structure.
The master identif ies read/write da ta in terms of a node’s relati ve position i n the ring,
not by a fixed addres s. The sequ ential locat ion of slav es corresponds to the order of
input and output data in the master's buffer.
The ring structure uses a distributed shift register. In a single bus cycle, data from
the master to the slaves (and from the sla ves to the master) is transferred. The cy cle
ends when the loo p back word is returned to the master. Ea ch no de is a c omponen t
on the shift register ring on which data is circulated.
The NIM’s EDS For a particular device to be recog nized on you r netwo rk, a corres pondi ng EDS file
must be exported to your master device. Thi s ASCII file contains informat ion abo ut
a device’s:
l
identity—the node’s cl assificati on is prese nted in term s of the manu facturer co de
l
data size—the master’s input buffer must account for the amount of data
expected from the device
NIM Limitations The STB NIB 1010 INTERBUS basic NIM supports up to 16 words of INTERBUS
cyclic data. It does not support the parameter communication protocol (PCP).

STB NIB 1010 Fieldbus Interface
Summary The fieldbus interface on the STB NIB 1010 is the point of connection between an
Advantys STB island bus a nd the INTERBUS netw ork. Like every IN TERBUS node,
the NIM has two nine-pin SUB-D connectors for data reception (in) and transmission
(out). The connectors are located on the face of the NIM.
Fieldbus Port
Connections
The in and out fieldbus interfa ces are lo cated on the front of the INTERBU S NIM at
the top:
It is recommended th at you use 9 -pin SUB-D connec tors compliant with INTERBUS
Club or corresponding international standard.
The in connector is optically isolated. The signal level is according to EIA RS-485.
20
890USE19600 April 2004
The pin-out for both the in (upper) and out (lower) connectors should be according
to the table below (pin numbers correspond to callouts in the figure above):
Pin Signal (in) Signal (out)
1DO1 DO2
2DI1 DI2
3 GND1 GND
4 unused unused
5 unused +5 V
6/DO1 /DO2
7/DI1 /DI2
8 unused unused
9 unused RBST (see note below)
Note: The RBST pin detect s the presen ce of a sub sequent node on the ring. In the
absence of this detection (or if the node has no out connector at all), the network
ring is closed.

Cable and
Connectors
The drop cable from the fie ldbus to the Adv antys STB INTE RBUS NIM (and t he one
from the NIM to th e nex t IN TERB US nod e) mu st have connectors t hat ob serve this
pin assignment scheme. INTERBUS networking cables are shielded, twisted-pair
electrical cables, compliant with INTERBUS standard DR-303-1. There should not
be an interruption to any wire in bus cables. Th is allows for a future specific ation for
use of reserved pins.

LED Physical Description
Overview The six LEDs implemented in the STB NIB 1010 INTERBUS NIM are visual
indications of the operat ing sta tus of th e isla nd bus o n an IN TERBUS net work . The
LED array is located at the top of the NIM front bezel.
General
Indications
22
The bottom three LEDs indicate the status of data exchange between the
INTERBUS fieldbus master and the Advantys island bus:
l
LED 4—RC (remote bus check)
l
LED 5—BA (bus active)
l
LED 6—RD (remote bus disa bled)
The top three LEDs indicate activity or events on the NIM:
l
LED 1—RUN
l
LED 2—PWR/UL
l
LED 3—ERR
The following tables describe the LED behavior in more detail. When you refer to
these tables, keep in mind:
l
It is assumed that th e PWR/UL LED is on co ntinuous ly, indic ating that the NIM i s
receiving adequ ate power. If the PWR/UL LED is off, l ogic power to t he NIM is off
or insufficient.
l
Individual blinks are approximately 200 m s. There is a 1-second i nterval between
blink sequences. For ex ample:
l
blinking—blinks steadily, alternating between 200 ms on and 200 ms off
l
blink 1—blinks once (200 ms), then 1 second off
l
blink 2—blinks twice (200 ms on, 200 ms off, 200 ms on), then 1 second off
l
blink n—blinks n (some number) times, then 1 second off
