General Information about INTERBUS
What is
INTERBUS?
INTERBUS is an open communication standard and is provided by over 200
manufacturers who offer wide range of different products. The high-speed network
is used for the connection of I/O modules, sensors, actuators, and control devices
to programmable logic controllers or large computer systems.
Features of the
INTERBUS
The INTERBUS is a master/slave network, optimized for efficient I/O data exchange.
It can communicate with up to 512 nodes over a distance of 12.8 km, and can read
1024 inputs and write 1024 outputs in 4 ms.
It offers an optimum flexibility of the configuration of control devices with regard to
the number of I/O stations and transmission distances. Despite exceptional
configuration flexibility, system performance and reliability of the I/O data have not
been compromised.
Based on an open system architecture, terminal block modules (TIO) and
Momentum I/O modules together with INTERBUS compatible products from other
manufacturers can be integrated easily and cost effectively into a control system.
Typical system configurations with Momentum I/O modules can be found in section
Examples of Configuration for INTERBUS, p. 17.

General Information about INTERBUS-Configuration
INTERBUS Configuration with TSX Momentum
General
information
The INTERBUS consists of remote bus and peripheral bus segments.
All bus segments transfer the same signals, but with differing electrical signal levels.
Note: TSX Momentum I/O modules can only be used on the remote bus and
remote bus branches.
Remote bus
The remote bus is used for the transfer of data over long distances, up to 400 m
between 2 nodes when using copper cable and up to 300 m between 2 nodes when
using HCS fiber optic cable. The remote bus is generated by the INTERBUS master.
No voltages are carried by the remote bus cable. When using copper cable, the
signal levels of the remote bus are implemented according to RS 485.
The bus operates full duplex with a transfer rate of 500 Kbaud.
Typical remote bus devices are, for example, Momentum I/O modules or bus
terminals.
The sections between two remote bus nodes are called remote bus segments.
Remote bus
branch
The remote bus terminal is created by a branch interface module (e.g.
170 BNO 671 00, 170 BNO 681 00). The branch interface module itself is a remote
bus node on the INTERBUS network. The Momentum I/O modules on the remote
bus branch are the same as those on the remote bus.
15
General Information about INTERBUS-Configuration
Switching off
remote bus
branches
The INTERBUS can only function properly as a shift register if all bus nodes are
present and intact. If one node is switched off or fails, the data transfer is stopped
by the bus master.
With INTERBUS topologies with branch terminals (see example Construction of a
Tree Structure, p. 21), the bus master can be configured so that remote bus
branches after a branch interface module (CMD Tool, keyword group definition) can
be switched off. The bus master then hides branches that are switched off with the
help of the branch interface module, creates a new total frame and restarts the
remaining bus. The data transfer on the INTERBUS only stops briefly for the identity
cycle. This behavior must be configured on the bus master.
If a branch that was switched off should be included in the network again, the voltage
supply must be turned on and the reconfiguration button on the branch interface
module must be pressed.
Switching off the remote bus branches is frequently carried out when performing
maintenance on machine or system parts or are not completely present during the
commissioning phase. Even if one or several nodes fail unexpectedly, it is still
possible that the bus where the node failure occurred continues to run, with the
exception of the branches.
Transition from
Copper Cable ↔
Fiber Optic Cable
There are two standard converters available for the transition from copper cable
(RS485) to fiber optic cable and vice versa.
l OPTOSUB, requires a voltage supply
l OPTOSUB PLUS, does not require a voltage supply
The converters can be used with the following modules:

The conversion from copper cable to fiber optic cable is done with OPTOSUB or
OPTOSUB PLUS, depending on the module used (see section Transition from
Copper Cable ↔ Fiber Optic Cable, p. 16).
A switch between copper cable and fiber optic cable can be made at any point.
However, a maximum of 2 OPTOSUB plugs per branch interface module can be
used.

Construction of a
Tree Structure
This example shows a tree structure using branch interface modules on the
INTERBUS. Each branch interface module is a remote bus node and enables the
connection of a remote bus branch to the remote bus. Using a tree structure, the bus
can be matched to the local requirements. Cabling expenditure can be considerably
reduced in this way.

General Relationship between I/O Unit and Adapter
General
information
The INTERBUS adapters 170 INT 110 03 and 170 INT 120 00 form the
communication interface between the I/O units and the INTERBUS network. It can
be plugged onto any I/O unit to form a fully functioning I/O module that
communicates via the INTERBUS.
The I/O modules of the TSX Momentum can be operated with any INTERBUS
master with INTERBUS certification.
The bus adapter is not a PCP node.
Note: The 170 INT 110 03 and 170 INT 120 00 adapters support the complete
diagnostic functionality of the INTERBUS firmware generation 4.
Functionality
Each bus node updates the INTERBUS telegram before passing it on to the next
node. The I/O module gets its output data from the telegram and transfers its input
data to the telegram.
Compatibility
The bus adapter can be combined with any I/O unit. The I/O modules are only
specified for connection to the remote bus and the remote bus branches of the
INTERBUS network.
Environmental
conditions
The environmental conditions of the bus adapter and the I/O units, on which they
can be mounted, match each other. Both are performed in protection type IP20
Further system data can be found in the user's manual for the I/O units of the
Momentum product family.

Assembly and Cable Connection
General Information about Connecting the Remote Bus Cable
Creation of a
cable plan
A complete cable plan should be created for the INTERBUS network, from which the
cable paths and the protective measures (EMC) on the cables are clearly visible .
The plan should identify the incoming and outgoing cable (incoming remote bus,
outgoing remote bus) of each module.
Connection of
the remote bus
cable
Modules within the INTERBUS network are connected to both of their plugs. One
cable is connected to the cable for the incoming remote bus and one the other is
connected to the cable for the outgoing remote bus.
Modules at the end of the network are only connected to one plug, that for the
incoming remote bus.
Types of
connections
The cables of the INTERBUS network can be planned in two different types:
l as copper wires
l in fiber optic technology
36
Assembly and Cable Connection
Connection of Remote Bus Cable, Copper Cable
Using Copper
Cable
Prefabricated cables are available in 3 different lengths for the remote bus, see
Overview of Ordering Information, p. 50. Each cable has two plugs for the
connection of two neighboring modules.
All other cable lengths must be made by the customer themselves, see Preparation
of the Remote Bus Cable, using Copper Wiring, p. 39.

Plug sets are offered to make your own cables in customized lengths. The set
contains one plug with pins (male) and one with sockets (female), see Overview of
Ordering Information, p. 50.
Before making the cable, please observe the following general guidelines:
l A 5 wire cable, shielded twisted pair, is required for the remote bus and can be
ordered by the meter (KAB-3225-LI).
l The maximum length of the remote bus is 12.8 km. The distance between two
remote bus nodes must be no more than 400m.
l The plugs for the outgoing remote bus always have pins, while those for the
incoming remote bus always have sockets.
l In the plug for the outgoing remote bus the connections 5 and 9 must always be
bridged, see Wiring diagram.
l The cable shield must be connected to the plug housing with a large surface area.

Central Shielding Measures for the INTERBUS
Central shielding
measures
For the commissioning phase, a large surface area connection should be made
between each cable shield and ground (FE/PE rail) directly after the cable enters the
switch cabinet.
Static discharge
Very long bus cables, which have been laid but not yet connected, are discharged
as follows:
Step
Notes for
connection the
cable shield with
earth
44
Action
1
Begin with the static discharge with the INTERBUS plug nearest to the FE/PE
rail.
2
Touch the FE/PE rail of the switch cabinet with the metal of the plug case.
3
Then plug the bus plug into the device, but only after this has been statically
discharged.
4
Discharge the cable’s other INTERBUS plugs in the same way and then plug
these into the device.
Note: The metal guide of the INTERBUS plug is internally connected with the cable
shield during the construction of the cable. If the bus cable plug is plugged into the
module’s INTERBUS interface, a short connection is automatically established
between the shield and PE.
Electromagnetic Compatibility Measures for Bus Adapter 170 INT 110 03
Overvoltage Protection for Remote Bus Lines (Lightning protection)
Overvoltage
protection
To protect the transmission equipment from coupled voltage spikes (lightning
strike), overvoltage protection equipment should be used in the remote bus cables,
as soon as it is laid outside of buildings.
The nominal discharge current should, in this case, be at least 5kA.
The lightning arrestors Type VT RS485 and Type CT B110 from Dehn und Söhne
GmbH & Co KG can, for example, be used. For the supplier address and order
numbers for protection equipment and accessories, see Overview of Ordering
Information, p. 50.
To protect an INTERBUS cable, two protection device groups are required in each
building. The first group (Type B110) is positioned where the cable enters the
building and is used as the lightning conductor. The second group (Type RS485),
close to the first node, is the overvoltage protection device.
Connection rules
for protection
devices
Before connection of the protection devices please observe the following rules:
l Install a functional ground (equipotential bonding rail)
l Assemble the protection devices near the building ground, so that the overload
current is diverted along the shortest route.
The cable(minimum 6mm2) to the building and functional ground should be as
short as possible.
l A maximum of 10 protection devices connected in series with 4 open land
sections, for connecting buildings to each other, are allowed in the INTERBUS
cables.
l Perform a Shield grounding (See Shield grounding with protection devices, p. 47)
of the INTERBUS lead according to the lightning arrestor used (type CT B110 or
type VT RS485).

Short description
General
information
The bus terminals 170 BNO 671 00 and 170 BNO 671 01 are remote bus nodes on
the INTERBUS and are used for the connection of a remote bus branch that has the
same extension limits as a remote bus.
The branch interface module 170 BNO 671 00 operates with the protocol chip SUPI
2. The branch interface module 170 BNO 671 01 operates with the protocol chip
SUPI 3, and supports the entire diagnostic function of the Generation 4 INTERBUS
firmware.
Mechanical
construction of
the branch
interface module
It has two interfaces (incoming and outgoing remote bus), provided as RS 485
interfaces and 1 RS 485 interface for the remote bus branch. The incoming remote
bus is electrically isolated. The interfaces conform to INTERBUS standards (DIN
19258).
The voltage supply and I/O periphery (relay output, keys) are connected via an 8 pin
terminal block.
The operating status is displayed using 7 LEDs.

Electrical Functions of Branch interface module 170 BNO 671 00 / 01
Supply
The supply voltage is UB = 24 VDC.
The logical supply (VCC = 5 VDC) is created from the 24 VDC. It is monitored. If the
voltage is in the tolerance range, a green LED will be switched on (ready). If the
voltage falls outside tolerance, a reset will be triggered.
Interfaces
The Branch interface module has an INTERBUS interface whose signals, inclusive
of GND, are sent outwards using three 9 pin. DSUB plugs (for incoming and
outgoing remote bus and remote bus branches). These signals are series
connected to RS 485 drivers.
These interfaces are suitable for the use of OPTOSUB. Up to two OPTOSUBs can
operate with the branch interface module.
The incoming remote bus signals are galvanically isolated from the other logic using
optocouplers. The outgoing remote bus and remote bus branch signals have a
potential connection. The branch interface module uses a special signal to test
whether it is the last node at the remote bus.
Peripheral
Signals
The terminals of the terminal block include a reconfiguration button, with which the
remote bus branch can be reconnected. A relay output is also available, which can
indicate an error at the remote bus branch.
The relay contacts are change over contacts.

Wiring of the 170 BNO 671 00/01 Branch interface module
Protection
Measures during
wiring
The following protection measures must be followed during the wiring of a branch
interface module:
l The fuses (F1) must be the correct size for the connected loads.
l The contacts of the relay output must be fitted with a protective circuit when
dealing with large loads, especially inductive loads (RC combinations, varistor,
or, with DC voltages of an inverse diode).
l Up to two 2.2 nF according to PE are required per contact when wiring contacts.
This depends on the degree of background interference (7 capacitors of this type
can be found in the capacitive by-pass terminal GND 001).
Supply of
voltages
The following voltages must be supplied externally:
l L+ for supply of internal electronics (terminals 8 and 7)
l 1L1 for supply of the relay output (terminals 2 and 1 or 3)
L+ and 1L1 are electrically isolated from each other and the incoming remote bus.
Note: The input for the reconfiguration request is not electrically isolated from the
logic supply. It is designed for using buttons.

Short description
General
information
The branch interface module 170 BNO 681 00 is a remote bus node on INTERBUS
and is used for the connection of a remote bus branch that has the same extension
limits as a remote bus.
The connection of the remote bus line uses fiber optic technology.
The branch interface module 170 BNO 681 00 operates with the protocol chip SUPI
3 and supports the entire diagnostic function of the Generation 4 INTERBUS
firmware.
Mechanical
construction of
the branch
interface module
It has two interfaces (incoming and outgoing remote bus), with fiber optic interfaces
and one RS 485 interface for the remote bus branch. The interfaces conform to
INTERBUS standards (DIN 19258).
The voltage supply and I/O periphery (relay output, manipulator) are connected via
an 8 pin terminal block.
The operating status is displayed using nine LEDs.

Electrical Functions of the Branch interface module 170 BNO 681 00
Supply
The supply voltage is UB = 24 VDC.
The logical supply (VCC = 5 VDC) is created from the 24 VDC. It is monitored. If the
voltage is in the tolerance range, a green LED will be switched on (ready). If the
voltage falls outside tolerance, a reset will be triggered.
Interfaces
The bus terminal has three INTERBUS interfaces. The incoming and outgoing
interfaces are designed for the connection of fiber optic cables. The remote bus
branch is connected using a 9 pin DSUB plug. This interface is suitable for the use
of OPTOSUB.
The user of the module must establish decide if it is the last node at the remote bus,
using an end identification slide switch.
Peripheral
Signals
The terminals of the terminal block include a reconfiguration button, with which the
remote bus branch can be reconnected.
A relay output is also available, which can indicate an error at the remote bus
branch. The relay contacts are change over contacts.

Mounting the Terminal Blocks
Connection
The I/O periphery and the voltage supply of the branch interface module are
connected using an 8 pin terminal block.
Selection of
terminal types
Two different types of terminal can be chosen according to its usage.
These are available as a set of 3, see Overview of Ordering Information, p. 50:

Use of coding
pins
Terminal block type
Cable cross sectional area
Cage clamp terminals
up to 2.5 mm2 (AWG 14)
Screw clamp terminals
up to 2.5 mm2 (AWG 12)
The module can be used in dangerous and safe voltage ranges. Dangerous
voltages are higher than 42.4 VAC or 60 VDC.
A set of plastic coding pins is supplied with the terminal block. Correct usage of
these coding pins will prevent insertion of terminal blocks that are wired for other
voltages.
Note: To ensure maximum possible protection, a coding must be implemented
during system setup.
76

Protection
measures during
wiring
The following protection measures must be followed during the wiring of a branch
interface module:
l The fuses (F1) must be the correct size for the connected loads.
l The contacts of the relay output must be fitted with a protective circuit when
dealing with large loads, particularly inductive loads (RC combinations, varistor,
or, with DC voltages of an inverse diode).
l Up to two 2.2 nF according to PE are required per contact when wiring contacts.
This depends on the degree of background interference (7 capacitors of this type
can be found in the capacitive by-pass terminal GND 001).
Supply of
voltages
The following voltages must be supplied externally:
l L+ for supply of internal electronics (terminals 8 and 7)
l 1L1 for supply of the relay output (terminals 2 and 1 or 3)
L+ and 1L1 are electrically isolated from each other and the incoming remote bus.
Note: The input for the reconfiguration request is not electrically isolated from the
logic supply. It is designed for use with keys.

Data Management and I/O Words
I/O Words and ID Code
Function mode
After connecting the supply voltage, the ID code of the I/O unit are automatically
read from the bus adapter. The ID code provides the INTERBUS master with I/O
type data (inputs and/or outputs) and the number of words required by the I/O
module in the INTERBUS telegram. After the INTERBUS master has received and
evaluated the ID codes from the I/O modules, it automatically begins data exchange
in real time.
The length information is given in I or O words, the higher of the two values decides
the I/O module position in the INTERBUS telegram.
The following values are possible: 1 ... 10, 12, 14, 16, 24 or 32 words.
Example for
determining the
ID code:
Example:
The ID code for the 170 ADM 350 10 is 0103 hex.:

Data Management for I/O Units
Addressing with
digital I/O units
The data exchange between the I/O unit and the bus adapter occurs 1:1.
With the TSX Momentum digital modules, the I/O points of the peripheral terminals
are always mapped according to the following principle:
l Only words are mapped to (max. 2 for 32 inputs or 32 outputs).
l The most significant word (MSW) is sent or received first.
l The words sent from the bus adapter to the I/O unit (output words) represent the
output values and parameters.
l The words sent from the I/O unit to the bus adapter (input words) represent the
input values and status information.
Example of data
management for
2 digital I/O units
Data management for the 170 ADI 350 00 (32 inputs) and 170 ADO 350 00 (32
outputs):
Word
Input data 170 ADI 350 00
Output data 170 ADI 350 00
1 (LSW)
Inputs 1 16
Outputs 1 16
2 (MSW)
Inputs 17 32
Outputs 17 32
LSW = Least Significant Word
MSW = Most Significant Word
Addressing with
analog I/O units
102
The I/O data sent to and from the bus master is mapped onto the terminals of the
I/O units in the following way:
l Each analog word is mapped onto a word.
l The most significant word (MSW) is sent or received first.
l The words sent from the bus adapter to the I/O unit (output words) represent the
output values and parameters.
l The words sent from the I/O unit to the bus adapter (input words) represent the
input values and status information.

Diagnostics
Error monitoring
104
The internal voltage supply (Vcc) is supplied by the I/O unit. Vcc is monitored and a
reset signal is generated if Vcc is outside the tolerance.
The potentially isolated voltage (Vcx) for the INTERBUS interface is generated using
a DC/DC converter and is not monitored.
A SUPI protocol chip controls the display LEDs that provide data transfer information
(bus active, remote bus check, remote bus disabled, , see section Display and
Operating Elements of the relevant module description) and the operating elements
(with components for the use of fiber optic technology).
The supervision time of the internal watchdog is 640ms and is signaled via the "BA"
LED.
An I/O error created by the I/O Unit generates a module error in the INTERBUS
adapter. This is recognized by the master and can be evaluated by the application
program. A module error does not automatically lead to a bus failure.
