Summary
The TELEPERM M process control system consists of functionally different components which are optimized for the various
problems encountered in process automation. Because of their
modular design, these components are also referred to as systems.
The TELEPERM M process control system is divided into
AS automation systems,
OS operation and monitoring systems and
CS 275 bus system.
The CS 275 bus system is responsible for communication between all TELEPERM M components and to components of other
systems by means of serial data transmission on stranded conductors (local bus) or coaxial cables (remote bus), if applicable
also via optical fibers. Data exchange is mainly between the AS
automation systems themselves as well as between automation
systems, OS operation and monitoring systems and central
configuring console and the AS and OS systems.
In order to satisfy the high demands made on data communication in process control technology, the CS 275 bus system has
been particularly optimized for the following demands:
Efficient data transmission
High data reliability and availability
Uniform system time
Automatic establishment of communication.
The CS 275 bus system has exceptional real--time properties.
Every bus participant is provided with the current process data
at all times. The capacity of the bus system is large enough
such that sufficient reserve is available for transmitting messages (e. g. process alarms) even with a high cyclic loading.
Automatic test routines guarantee data reliability. The user can
configure which messages must be acknowledged by the receiver. The failure of a bus component has no influence on the
communication between the other participants.

Summary
The bus system can be designed in redundant form if extremely
high demands are placed on the availability. This does not result
in additional configuring requirements.
Events are always recorded with the exact time since the individual bus participants can synchronize their clocks via the bus
system.
The simple configuring is one of the most important characteristics of the CS 275 bus system. Convenient system functions are
used to establish the connection, intervention by the operator is
not required. The parameters to be transmitted (analog/binary
values, messages etc.) are already declared when configuring
the automation systems and the operation and monitoring systems. The establishment of the connection for the operation and
monitoring systems is carried out automatically when starting
up, it is merely necessary to enter a coupling command for connections between automation systems.
Optimum utilization of the high performance of the CS 275 bus
system is only guaranteed with a large number of participants if
certain rules are observed when configuring the bus and if it is
ensured that the cyclic bus loading does not exceed 70 % of the
bus capacity. Thus 30 % are available for acyclic data transfer
(e. g. messages).
In the case of a specific configuration, the cyclic bus loading is
independent of
the configuration of the transmitter blocks in the automation
systems,
x the transmission mode selected and
x the processing cycle of the transmitter blocks.
Information on the establishment of data transfer with the coupling blocks for data exchange via the CS 275 bus system is
included in the publication ”Configuring guidelines” in the
Manual ”CS 275 bus system”. This publication describes the
determination of the cyclic bus loading using the bus loading
characteristics and lists the cyclic bus loading for a selected
configuration.

Mode of operation
Transfer control, data protection and transfer
Transfer control
Sequential data transmission systems require a transfer control
unit for organization of the data traffic on the line. This unit organizes and coordinates the data traffic so that only one subscriber transmits data on the bus at a time. This transfer control
function is decentralized in the CS 275 bus system. The availability of the data transmission system is therefore mainly determined by the line length.
Data transfer control in the CS 275 bus system operates according to the token principle, i. e. each participant (local bus interface module) accepts the transfer control function (master function) from time to time.
In a system with n participants, there is only one participant in
the master condition at any one time, all other (n--1) participants
are in the slave condition. The change of the master function
from one participant to another is called master transfer. Since
every participant can assume the master function, this function
has n--times redundancy in a token system.
The ”bus protocol” also specifies how a participant becomes
master and how this status is transferred within the system. The
protocol complementary methods for the assignment of the
master function to a participant are:
Time-out-controlled master transfer
Request-controlled master transfer
Instruction-controlled master transfer
Data protection
Data protection is achieved in the CS 275 bus system by generating line and column parities and is referred to as block parity.
The following errors are detected by the data protection:
1-bit, 2-bit and 3-bit errors,
Hamming distance d = 4
Odd bit errors, 1-, 3-, 5-, 7- and 9-fold errors,
independent of location
Error bursts < 11 bit long
Error pattern (with exception of rectangular format).
This presents the following advantages:
Easy configuring of communication (only the transmitter and
receiver blocks must be configured, not the interface modules
for 20-m local bus)
Messages to several subscribers are simply transmitted on
the bus (several receiver blocks can access one transmitter
block)
Symbolic addressing (block name and number)
Complete documentation of all connections by self-documentation of systems
The communication procedure can be configured in a still
simpler manner in full-graphic mode on the screen by means
of the configuring tool PROGRAF and can also be documented in the same representation (see page 2/5).
Cyclic data transfer
Analog values are transmitted cyclically with the coupling
blocks AKS/AKE, binary values with the BKS/BKE blocks and
characters with the ZKS/ZKE blocks.
There are also further functions in addition to the cyclic data
transfer.
These functions include image updating in an OS operation and
monitoring system. The updating time is < 2 s in the TELEPERM
M process control system. In order to guarantee this value, the
bus system provides a function ”Read parameters”. This enables up to 30 different parameters per message to be read
from one AS system. The functional sequence is as follows:
The OS system sends the request to the bus system to read the
corresponding parameters from several AS systems for image
updating. The addresses of these parameters have already
been converted to on-line-accessible parameters from the symbolic addresses of the configuration during the system start-up.
Thus, the bus interface modules can read the desired information out of the automation system memory by DMA, generate
corresponding reply messages and return these to the corresponding OS systems.
The bit error rate of p =10- 5 satisfies the requirements of IECSC-65-WG6 for process buses. According to this, an undetected transmission error in a message may occur on average
once in every 1000 years (at 250 kbit/s).
Data transfer
Blocks in the TELEPERM M system components are available for a
cyclic and a sporadic (acyclic) data transfer via the bus system:
Dedicated transmitter and receiver blocks handle all functions
associated with data transfer. Thus, the data transfer can be
established easily by configuring, just as the automation functions.
The user need only carry out the following to produce communication:
-- The inputs of the transmitter block must be provided with the
addresses of the data to be transmitted
-- The transmitter block must be inserted into the processing
sequence
-- The outputs of the corresponding receiver block must be
linked accordingly in another automation system
-- The receiver block must be inserted into the processing
sequence
-- The connection to the transmitter must be established using a
coupling instruction.

Mode of operation
Addressing, transmission modes
This method has the following important advantages:
There is far less loading on the bus system since only the
information is read from the automation system which is currently displayed on the monitor channels
Data need only be stored at one position as a result of the
distributed data base principle. Modifications are therefore
only necessary at one position
No special planning for the OS systems is required in the
automation systems (exception: curve display)
Acces to information in the automation systems by another
computer is possible without additional planning (by using the
function ”Read parameters”).
Addressing
The cyclic data exchange is also used for a life test of all participants connected to the CS 275 bus by an OS operation and
monitoring system. Each failure and also the return of a participant is supervised and signalled.
The bus coupler behaves like a participant with respect to each
bus. It has an address on each bus.
The addressing of the participants of the bus system is oriented
towards the transmission of messages between several autonomous buses and within a bus.
Each participant is identified by two addresses:
Bus address (0 to 7), i. e. 8 autonomous buses are possible.
7 bus couplers are needed in this case.
Participant address (0 to 99).
These two addresses are set on the local bus interface module
using jumpers or DIP switches.
Sporadic data transfer
Sporadic data transfer is necessary to rapidly pass on modifications in the process control system to other participants. Typical
examples are faults or changes in status (e. g. motor on/off)
which detects the automation system. Messages exchanged
between several automation systems are transmitted by means
of the coupling blocks MKS/MKE.
A status word is assigned to each function block for processing
with standardized operation and monitoring as well as to driver
blocks for I/O modules with standardized display. The changes
in signal are detected event-controlled by the status word or by
the MKS block, provided with the actual time (MKS only) and
transferred to the bus system. This then transfers MKS messages to a maximum of 6 participants (typically OS systems
and higher-level computers) which have ”registered” themselves for this information when the complete system was
started up. This presents the advantage that the automation
system need only transmit one message with one or several
destination addresses. In addition, only those stations receive
the information which actually require it.
Data transfer with OS systems and computers takes place using
the functions ”Read parameters” and ”Write parameters”.
Transmission modes
A differentation is made between two transmission modes when
configuring and defining the AKS and BKS transmitter blocks:
-- Direct coupling (DI)
-- Common data (CD).
Direct coupling (DI)
The registered participants are directly addressed by the transmitter blocks, i. e. each participant only receives the data which
is assigned for it. Up to 6 receivers can be registered with a
transmitter block and receive the data (analog or binary values)
pertaining to it with each transmission cycle of this block.
Any participant on the bus can be a receiver. Transmission can
also take place via bus couplers. A receiver is entered as such
in the transmitter block in the respective automation system.
The MKS block only operates in direct coupling mode.
Common-Data (CD)
The transmitter block sends the data simultaneously to all connected participants of a particular bus. Thus certain identical
data can be planned in a transmitter block for many participants
on a bus and many destination addresses can then be reached.
Fig. 2/2
Sporadic/acyclic data exchange, example OS/AS and AS/AS
Siemens PLT 130 . 1994
The CD procedure can only be used for subscribers with the
same bus address. Addressing via bus couplers is not possible.
The participants on a bus connected via a bus coupler can be
addressed via their own CD procedure.

Mode of operation
Redundant operation mode, transmission reliability, synchronization
Redundant operation mode
Time synchronization
The CS 275 bus system can be redundant in order to increase
the availability. The interface modules for the local bus are already designed for a redundant local bus line. A bus converter
UI and a connector board AF are required for connection of a
redundant remote bus per remote bus cable. Different remote
bus cable lengths are permissible between bus A and the redundant bus B.
The real-time clocks of the particular TELEPERM M subsystems
are synchronized by signals from an OS operation and monitoring system. This can be synchronized by a radio clock (DCF 77
radio transmitter) or a standard clock.
The bus system is started up on bus A. Besides this, no preference is given to either bus. The bus system carries out a cyclic
test to see whether a changeover criterion is satisfied. An automatic changeover is carried out if this is the case.
The subscribers on the CS 275 bus system must be synchronized with high accuracy. Because of it, the transit time of the
synchronization message is corrected within the milliseconds
range by the internal buffers of the local bus interface modules
of the automation systems and programmable controllers or by
bus couplers.
Changeover criteria
An image of the local bus is generated through each bus line
approx. every 750 ms. If the image of the passive bus contains more entries than that of the active bus, the system
switches to the passive bus.
If the images on the two bus lines are the same, but the master detects a transfer request on the passive bus, a changeover also takes place to the passive bus. A slave sends transfer requests on the passive bus if transfers are no longer
possible for it on the active bus.
If the current master fails because of a fault, the slave with the
smallest participant address assumes the master function on
the previously passive bus (if one exists).

General notes, local range
The CS 275 bus system is physically divided into
-- a local range up to 20 m (local bus) and
-- a remote range up to 4 km, or up to 12 km with bus couplers.
Each participant requires a local bus interface module to enable
bus communication, redundant systems such as the AS 235 H
automation system require two modules. These interface modules convert the various internal system bus interfaces of the
participants into the uniform local bus interface. The transfer
control function for the complete bus is transferred from participant to participant. This function is also handled by the local
bus interface module of the respective participant which currently possesses the master function.
The design of the local bus interface modules depends on the
participant system to be connected. Thus the modules e. g. for
connection of the automation systems are of double ”EUROPE”
format, and those for connection of SICOMP industral PCs are of
AT format. In the local range, the local bus interface modules
are connected together into a ”local bus island” using cables.
Systems not belonging to TELEPERM M require additional coupling software to match their internal communication interface to
that of the CS 275 bus system. This software is available,
amongst others, for the connection of personal computers with
MS-Windows or UNIX operating systems, for workstations and
for SIMATIC S5 programmable controllers.
In the remote range, individual participants or complete local
bus islands are connected to the remote bus via inductive bus
couplers UI. Different designs of coaxial cable are available for
the connection depending on the associated mechanical stress.
The local bus is always redundant, the remote bus can be either
single or redundant.
Local range
The transmission is on multi-conductor cables with a max. total
length of 20 m.
Three line signals are used. The data themselves are transmitted sequentially on one data line. A second line transmits the
clock, the third is used for synchronization.
It is necessary to differentiate between electrical participants
and (bus) participants when determining the maximum possible
number of participants. Electrical participants are the local bus
interface modules, the bus converter modules UI and connection multiplexers AV (for connection of a local bus interface
module).
(Bus) participants are e.g . an AS 215 automation system
(1 electrical participant) or an AS 235 H automation system
(2 electrical participants). Up to 9 electrical participants are
permissible on a local bus. For example, this means $ 7 bus
participants for a local bus island connected to a redundant
remote bus via two bus converters UI (cf. Figs. 3/1 and 3/2.)
Depending on their type, the local bus interface modules can be
either floating or non-floating. Certain design guidelines must be
observed when connecting into a local bus island in order to
prevent interferences (also refer to Manual ”TELEPERM M,
Information and Guidelines for Planning, Installation and Operation”, Order No. C79000-G8076-C417).

The following therefore applies:
In the case of electrically isolated local bus interface modules,
the ground potential of the bus interface is decoupled from the
ground potential of the subrack system. In addition, the 0-V
level of the interface logic is matched to the potential of the coupling partner via the local bus cable. This prevents equalizing
currents from flowing via the local bus cable in the event of voltage differences > 0.2 V between the grounds of the coupling
partners. These currents would interfere with the bus traffic.

In this manner, it is possible e. g. to extend a local bus island
(0-V island) consisting of basic and extension cabinets by
means of external, electrically isolated local bus participants
(N-AS/N-AT). Any local bus interface modules can be linked
together within this local bus island since they are powered from
the same power distribution subrack. The following conditions
apply: max. length 20 m, max. 9 participants, where each bus
converter UI also counts as one participant.
The cables are fitted at one end with a front plug for connection
to the local bus interface modules, the other cable end is prepared for the connection and is soldered to the front plug of the
cable of the next interface module. A single front plug is required for the n-th local bus participant. This is not necessary
for standard connections, e. g. to the bus converter UI for the
remote bus, since prefabricated cables are available with
looped-through wiring to up to 5 plugs.
The total length of the cables must not exceed 20 m.

Connection distributor
The connection distributor has a vacant plug connection to the
redundant 20-m local bus for the connection of configuring aids
(SICOMP industrial PC with PROGRAF program package) and
bus diagnostic aids. It must be connected to the local bus via a
separate cable connector for this purpose.
Remote range
Transmission takes place via a coaxial cable up to distances of
4 km. The signals are self-timing bipolar square-wave pulses.
The coupling to the remote bus is reaction-free.
Up to 100 bus participants can communicate with one another
via the remote bus. The remote bus and local bus are connected
together via inductive bus converters UI. The complete bus
system therefore has the same information.
Two autonomous bus systems are connected together via a bus
coupler so that only the information intended for the other bus is
transferred. The bus coupler is counted in each of the two autonomous bus systems as one bus participant.
Siemens PLT 130 . 1994
Inductive bus converter (bus converter unit UI)
A bus converter is required to connect individual participants or
a local bus with several participants to a remote bus. It performs continuous signal conversion between the local bus and
the remote bus or vice versa without intermediate storage. The
coupling is inductive and non-reactive.

peaks in the kA range. It is installed where the remote bus cable
enters the building. The fine protection reduces the residual
voltage which passes the coarse protection down to a value
between the internal conductor and the screen of the remote
bus cable which is harmless for the amplifier of the inductive

An increased tensile strength up to 25 000 N is possible using a
cable with additional armouring. If protection against damage
by rodents and mechanical damage is required, the cable with
additional steel-tape armouring should be used.
Connection of remote bus cables
It may be necessary when using remote bus cables to connect
sections together. The maximum available length of the in-house
cable is 200 m, with all other types of cable 1000 m.
The type of connection depends on the type of cable. Standard
and in-house cables are connected by splicing or by using RF
plugs. The 2 other types of cable can be connected by splicing.
To provide protection against mechanical damage, the connection should be enclosed in a metal sleeve. The cable armouring
can be electrically connected using a copper cable (e. g. as

Interface module for 20-m local bus (N16-M), 16 bit
Application
To connect the OS 265-3 operation and monitoring system and
SICOMP M minicomputers to the CS 275 bus system. The
SICOMP M minicomputer must be equipped with the KSN-16M
coupling software to adapt bus communication. Local bus coupling (< 20 m) with other participants is only possible if these
have the same earth potential. Both coupling participants must
have the same earthing concept (e. g. OS 265-3 and AS 235/K/H
systems). The remote bus connection unit (cf. page 4/11 must be
used in all other cases and provides electrical isolation together
with the bus converters UI (page 4/9).
The module handles the following duties connected with data
transmission:
Collection of parameters and processing of input/output instructions on the I/O interface channel of the SICOMP M minicomputer
Signalling of operating statuses and faults with defined displays.
via the serial bus. A message can be sent to a single bus participant, to several participants or to all participants.
Apart from certain cyclic messages, the receiver acknowledges
every message received.
The transmitter is immediately informed when a message has
been received without faults. In certain cases, the required data
are also transmitted immediately with this feedback, thus enabling short reaction times.
The interface module N16-M stores the messages in its transmitter and receiver buffers until they are processed and transmitted and thus dynamically decouples the OS 265-3 system or
the SICOMP M minicomputer from the data transfer on the bus
during times of peak loading. To reduce the time required for
organizational tasks, the interface module collects several messages over a specific period and combines these into a package. This is not the case if short reaction times are required.
In addition to the data messages, the interface module also
generates and processes organizational messages together
with the other interface modules on the CS 275 bus system.
These are required, for example, to transfer the master function,
for routing information, redundancy tests, monitoring and signalling information.
Time synchronization
The interface module receives time messages and routes these
on to the OS 265-3 system or SICOMP M minicomputer. In the
opposite direction, it can also receive the time from the
OS 265-3 system or SICOMP M minicomputer and transmit it on
the bus in order to synchronize the participants.
Diagnostic functions
The interface module detects and signals static and dynamic
faults and any states which could be critical for the bus loading.
It monitors the processes on the bus, on the interfaces to the
user system and in the interface module itself.
During operation, cyclically triggered test programs carry out an
extensive hardware test of the interface module. Faults are
therefore early detected and malfunctions and cumulative faults
are thus prevented. External bus diagnosis via the coupling
software is also possible. The interface module provides a diagnostic list with 23 positions which can be read for this purpose.

Communication between TELEPERM M systems and
non-Siemens computers
Data transfer between TELEPERM M systems and a
non-Siemens computer via the CS 275 bus system is carried out
using the same messages which are used for communication
between TELEPERM M systems. The defined types of order
(format, coding, acknowledgement mode) and the function of
the hardware interface (N-V.24) are described in the Instructions
for the interface module N-V.24 and in the Manual ”N-V.24, Coupling of non-Siemens computers to the CS 275 Bus System”.
Coupling software must be installed in the external computer
which matches the computer to the communication conditions of
the N-V.24 interface.
Setting of address
In order to differentiate between the individual interface modules
in the autonomous bus system, each interface module must be
allocated a so-called participant address. In order to differentiate between several autonomous buses connected via bus couplers, each interface module must be allocated a bus address.
These two addresses are set using plug-in jumpers on the front
panel of the interface module.

Interface module for 20-m local bus (N-S5)
Description and ordering data
Mode of operation
Data received via the CS 275 bus system pass through the line
protocol controller of the bus interface logic in bit-serial mode
and are placed into intermediate storage. The microprocessor
reads the data byte-by-byte and stores them in the buffer
memory of the module. Up to 70 complete messages can be
stored in the buffer memory.
As soon as sufficient space is available in the dual-port RAM for
a complete message, this is entered into the receiver order list
of the dual-port RAM. Transmit messages are transferred from
the function blocks of the KSN-S5E coupling software to the
dual-port RAM system interface and entered into the transmitter
order list.

Slot: extension slot in AT format in the above-mentioned
devices.
The interface module N-AT contains:
An SAB 80 188 microprocessor for controlling and monitoring
all functions
A dual-port RAM system interface to the AT bus with associated control logic
An interface to the 20-m local bus with bus interface logic.
Mode of operation
Data received via the CS 275 bus system pass through the line
protocol controller of the bus interface logic in bit-serial mode
and are placed into intermediate storage. The microprocessor
reads the data byte-by-byte and stores them in the buffer
memory of the module.
As soon as sufficient space is available in the dual-port RAM for
a complete message, this is entered into the receiver order list
of the dual-port RAM. Transmit messages are transferred from
the coupling software to the dual-port RAM system interface
and entered into the transmitter order list.

Bus coupler
Description
Fig. 4/18
Bus coupler (BK--FF), subrack configuration
Application
Mode of operation
Bus couplers are used for data transfer between participants on
independent remote buses (BK-FF). They enable decoupling of
the data transfer on the buses as well as distances between two
participants up to 3 x 4 km.
A bus coupler acts like any other participant on the bus. It has
an address on every bus. A participant on bus 1 sends a message to a participant on bus 2 by first addressing the bus coupler. This stores the message briefly independent of the current
message transfer on bus 2 and acknowledges receipt to the
transmitting participant.
The bus line can be single or redundant. Bus couplers can also
be used in parallel to increase the transmission performance. A
maximum of two bus couplers may be connected in series between two participants which exchange information.
Parallel bus couplers
The bus coupler transmits the message on bus 2 if it becomes
the master on this bus. The participant to which the message is
addressed accepts the message and acknowledges receipt to
the bus coupler.
If the coupling capacity of a bus coupler is not sufficient, the
transmission performance can be increased by approx. 100%
by using a second bus coupler. This parallel connection of bus
couplers leads to limitations in performance if one of them fails
(this is not a redundant connection).
Redundant remote bus 1
Redundant bus couplers
If the coupling capacity of a bus coupler is sufficient, a redundant system can be produced using a second bus coupler. In
this case, the second bus coupler automatically takes over the
coupling function if the first bus coupler fails.

The bus coupler consists of
-- 2 interface modules for bus coupler (N-BK),

Overvoltage protection
Description
Fig. 4/23
Coarse overvoltage protection 6DS9 208-8AA
Fig. 4/24
Fine overvoltage protection 6DS9 210-8AA
Application
Design
The coarse and fine overvoltage protection components largely
protect the participants connected to the CS 275 bus from destruction as a result of overvoltages which result from interferences in the remote bus cable. The division into coarse and fine
protection means that it is possible to optimally match the overvoltage protection to the respective system.
Coarse protection
The coarse protection limits powerful, high-voltage pulses to the
arc voltage. It can briefly handle currents in the kA range.
It is connected via an M5 threaded bolt to the earthing system.
The screens of the remote bus cables which are combined in
the housing of the coarse protection can be connected if required to the earthing system either directly or via one of the two
lightning arresters (floating design).
The fine protection reduces the residual voltage between the
internal conductor and screen which passes the coarse protection to a measure which is non--hazardous for the amplifier of the
inductive coupler in the bus converter Ul.
The use of overvoltage protection components is not mandatory
for operation of the CS 275 remote bus in non-disturbed system
environments. But their use is recommended if the effect of
overvoltages onto remote bus cables cannot be excluded.
Important notes:
The coarse and fine protection components do not replace a
lightning protection system installed according to the regulations.
In conjunction with the so-called primary lightning protection
(connection and earthing of steel armoring, equipotential bonding etc.) you can reduce the extent of damage to the bus participants as a result of a lightning stroke, but this does not provide
complete protection from the damage of lightning.
4/16
The coarse overvoltage protection 6DS9 208-8AA is fitted in a
cast aluminum housing with degree of protection IP 54 and dimensions (l x w x h) 125 mm x 80 mm x 58 mm. It contains 2
lightning arresters.
The coarse protection is suitable for all types of remote bus
cables.
Fine protection
The fine overvoltage protection basically consists of two Z
diodes and a terminator for the remote cable which can be connected when needed via the connecting splicing plate on the
connector board AF instead of the resistor present there. These
components are located on a miniature PCB which can be fitted
in the connector board 6DS9 203-8CA or --8DA.
The coarse and fine protection components can also be retrofitted in existing system.

The coarse overvoltage protection must be provided for all remote bus cables prior to their exit points from the building and
also in the immediate vicinity of the foundation earth connection.
The connection between the coarse protection and the foundation earth must be kept as short as possible.
The coarse protection is also recommended if the remote bus
connects cabinet groups which are positioned more than 50 m
from one another within a building. In this case the coarse
protection must be installed directly next to the last participant
before the longer inhouse cable, and connected to the potential
earth of the cabinet.
The fine protection must be provided for each bus participant
which is directly connected to a coarse protection component.
Fine protection is required for both participants if the distance
between the bus participants is > 25 m.
Siemens PLT 130 . 1994
The cable clamps for the various types of remote bus cable are
included in the delivery of the overvoltage protection.

Application
Coaxial cable 2YC(mS) CY1.6/10-75(Z2/5) vs sw is used as
standard as the remote bus cable. The cable may be routed in
potentially explosive atmospheres to DIN 57 165/VDE 0165,
Section 5.6.1 and is also suitable for burial in the ground. Max.
permissible length 4000 m.
Coaxial cable 2YC(ms)CY 1.0/6.5--75(Z2/5)vs ws (in-house
cable) can be used indoors. Max. permissible length 2000 m.
The cable 2YC(mS)CYbY1.6/10-75(Z2/5) vs (F 0.8 vzk) sw
(Order No. V45466-D21-B65) must be used if the tensile
strength of the standard remote bus cable is insufficient. This
has additional armouring to increase the tensile strength of the
cable to 25000 N.

Connection of remote bus cables
It may be necessary when using remote bus cables to connect
sections together. The type of connection differs depending on
the type of cable:
Standard remote bus cable V45466-D21-B35 and in-house
cable V45466-D17-B135
These cables can be connected by splicing or by using RF
plugs.
Remote bus cables V45466-D21-B65 and -B55
Only splicing is possible for connecting these cables. To provide additional protection against mechanical damage, the connection should be enclosed in a metal sleeve. The cable armouring can be electrically connected using a copper cable
(e. g. as additional overvoltage protection) and secured to prevent tension. The sleeve is filled with sealing compound following assembly.
All parts required for the connection, both for the cable connection itself and also the sleeve and sealing compound, can be
obtained as a parts kit for splicing coaxial cables. Instructions
are included with the kit.

SY--TRANS 300 CS gateway
Description
Connections
The CS 275 interface is connected via a cable for 20-m local
bus (cf. page 4/15). The transition to the CS 275 remote bus can
be made via the remote bus connection unit FAE (page 4/11) or
-- in the case of cabinet installation -- via the remote bus connection subrack S5 (page 4/12)
The SINEC H1 interface is connected via a 15-pin sub-D plug
according to the SINEC H1 guidelines (cf. Catalog IK 10 ”Industrial Communications Networks”).
The Ethernet interface with TCP/IP or DECnet is available via a
BNC plug and also via a 15-pin AUI plug 1). Thin-wire or thickwire cables can be used for the connection.
Bild 5/1
SY--TRANS 300 CS gateway
Application
The SY-TRANS 300 CS gateway enables bidirectional data
transfer at high rates between participants on the CS 275 bus
system and computers connected to an Ethernet bus (LAN according to IEEE 802.3). The standard network protocols which
are alternatively available are TCP/IP, DECnet or SINEC H1 (ISO
transport).
The thin-wire cable is connected via BNC plugs -- via a T-connector when looping through -- if a BNC connection is also present on the computer. If the computer only has an AUI connection, a transceiver is required for each transition from AUI to
thin-wire.
The software component is a communications server (client/server architecture) with a simple communication interface to the
user: the library OPEN CS. This contains command procedures
and library routines and can be executed in the computer under
one of the following operating system platforms:
VMS, OPEN VMS, ULTRIX, OSF/1, UIX, SUN OS, SINIX, SCO
UNIX, MS-DOS, Windows NT (others on equiry).
The network protocols TCP/IP, DECnet or SINEC H1 (ISO transport) can be used in the LAN.
User applications in the computer can be readily linked to automation systems of the TELEPERM M process control system
using simple library calls. The following AS automation systems
can be communications partners: AS 230 2), AS 230 K 2), AS
235, AS 235 K und AS 235 H.
Library calls are offered as standard for the following CS 275
functions:
-- Y-startup
-- Read parameters
-- Write parameters
-- Receive AKS, BKS und MKS messages.
The library OPEN CS can also be extended by further CS 275
functions for specific projects.
Design
Further functions have already been implemented which permit
the design of a fault-tolerant system.
The gateway comprises the basic hardware and a software
component which handles the communication server function in
the computers connected to the LAN.
The basic device contains
-- an AT-compatible basic PC module,
-- the local bus interface module N-AT as the interface to the CS
275 bus system and
-- the CP 1413 communications processor for SINEC H1
or
an interface module for the Ethernet bus.
A power supply unit is used for DC 24 V oder AC 115 to 230 V.
The system software is present as firmware in EPROMs and
need not be loaded. The software is different depending on the
required network protocols.
As a result of the housing depth, the basic device can only be
installed hanging vertically with the front panel upwards in
TELEPERM M standard cabinets (also those with depth of
600 mm).
1) AUI = Attachment Unit Interface.
2) These automation systems are no longer available.
