The 3UF5 SIMOCODE-DP System
There is less and less time in between
ordering and the start-up of
a system – however, the requirements
made on motor feeders are
increasing. A system should, for
example, be compact, intelligent
and powerful. Every motor has
optimum protection, the scope of
wiring is as small as possible and
spares must not mean high storage
costs.
To meet all these requirements, the
system designer has to have extensive
knowledge of the complete range of
low-voltage switchgear. The new
communications-capable
SIMOCODE®-DP 3UF50 – Siemens
Motor Protection and Control Device -
Decentralised Peripherals – makes life
easier for the system designer.
SIMOCODE-DP is a tried and
tested system
SIMOCODE 3UF10/20 devices have
been in use all over the world for more
than five years. They protect and
control motors for the chemical, oil and
gas industry. Motors with heavy
starting duty as used in paper, cement
and metal production for example are
no problem for SIMOCODE.
SIMOCODE also helps ensure that
high-availability systems such as coal,
gas and hydro electric plants run
around the clock. SIMOCODE provides
the communication between the
master level and the automation level
via the PROFIBUS®-FMS/SINEC®-L2-
bus.
The new SIMOCODE-DP 3UF50 with
integrated PROFIBUS-DP interface has
established itself worldwide in a short
time span. It protects and controls for
example Cement and Petrochemical
industries in Malaysia; Paper,
Chemical, Textile, Steel, Gas and
Waterwork plants in Europe; Chemical
plants in South Africa; Food and
Consumergoods industries in South
America and like the Steel industry in
North America will soon be installed in
a Steel plant in Australia.
The new SIMOCODE-DP 3UF50 is
based on the tried and tested
SIMOCODE 3UF10/20. In addition to
the existing control functions, such as
direct-, reversing-, star-delta starters,
there is now the possibilty to
implement user-specific controls by
using the freely assignable inputs and
outputs and the built-in truth tables,
timers and counters.
The existing motor protection
functions (overload, phase failure and
current imbalance detection) have
been supplemented by thermistor
motor protection and earth-fault
monitoring.

Thermistor-Type Motor Protection
Without Compromise
Electrical equipment such as AC
motors and transformers need
protection against excessive heating.
Unbalanced current consumption,
phase failure or a stalled rotor are
some of the possible causes of
overloading.
Overload protection
SIMOCODE-DP protects the load,
independent of the automation level,
against overload, phase failure and
current imbalance. The 3UF50 basic
unit can also be used as an
autonomous, solid-state overload relay
for motor protection.
Finely adjustable adaptation to
start-up conditions
It is possible to select a tripping class
in six steps from CLASS 5 to CLASS
30. The tripping time can be finely
adjusted to the start-up conditions –
and the utilisation of the motors can
be optimised.
Built-in thermistor motor protection
Thermistor motor protection is used for
the thermal protection of motors. The
temperature is measured directly at
the motor windings via a PTC or NTC
thermistor detector and is evaluated by
SIMOCODE-DP.␣ No additional
evaluation devices are required, thus
saving space in the switchboard.
Apart from binary thermistor detectors,
SIMOCODE-DP also evaluates
analogous (KTY) thermistor detectors.
KTY detectors incorporate a resistance
curve which rises linearly with the
temperature. Therefore, a warning and
a tripping threshold can be set in the
SIMOCODE-DP.
A considerable advantage.
For motors with a thermally critical
rotor, e.g. slipring and squirrel-cage
motors with increased power, the combination
of thermistor-type motor protection
and electronically delayed overload
relay offers full thermal protection –
thermistor-type motor protection.
Earth fault monitoring
always available
This protective function is also offered
by the SIMOCODE-DP communications-capable
motor protection and
control device. The internal earth fault
detection can be activated in addition
to the thermistor evaluation.
4
For motors with 3-wire connection,
fault currents which exceed the
current setting I e (during nominal
operation) by 30% can be detected
with the internal earth fault detection.
The SIMOCODE-DP system is also
suitable for a precise earth fault
detection. A version is available with
external earth fault detection. By
connecting an external summation
current transformer, fault currents of
0.3 A, 0.5 A and 1 A can be detected
for both 3 and 4-wire motors.
An additional evaluation device is not
required, and the space requirement in
the cubicle is further reduced.
Protection against stalled rotors
Protection against the stalling of
motors during normal operation is
achieved by a comparison of a settable
current limit.
Resettable everywhere – manual,
remote and automatic reset
A reset at the device is implemented
with the Test/Reset button. By connecting
a pushbutton to the inputs, via
PROFIBUS-DP or via the Test/Reset
button at the operating module, a
remote reset can be implemented. An
automatic reset can also be
configured.
Reduction of variants by large
setting ranges: 0.25 A – 820 A
A current window from 0.25 A to
820 A is covered using only six units.
This reduces product selection – and
saves on spares costs.

Tolerance < ± 10%
With a tolerance of less than 10%,
SIMOCODE-DP has an accurate
tripping curve which guarantees an
optimum utilisation of motors.
Long-term stability also contributes to
the high degree of accuracy.
Cost reduction by built-in current
transformers
Current detection is archieved via three
current transformers which are
integrated in the device. This means that
savings are made three ways – i.e.
space, wiring and additional device
requirements.
Easy ‘through feed ‘connection
Feeder cables up to 100 A rating can be
easily connected to the 3UF50. The
cables are not terminated to the device,
but are fed through 3 integral conduits
in the device housing –
a major saving in installation time.
Protection of motors in the EExe range
The SIMOCODE-DP system complies
to the regulations for overload
protection of explosion-protected
motors of the „increased safety“ type
EExe DIN EN 50019/ DIN VDE0165,
DIN VDE 0170/0171 and to the test
regulations of the Federal Institute for
Physics and Technology and the test
requirements of the Federal Institute
for Physics and Technology No. 3.53-
14605/96.

Wide Scope of Control Functions
With the SIMOCODE-DP system nine
different control functions can be
implemented:
• Overload relay
• Direct starter
• Reversing starter
• Star-delta starter
• Dahlander
• Pole-changing switch
• Slide valve (Encoder)
• Solenoid valve
• SIKOSTART® 3RW22
(Soft starter)
In addition, permanent or nonmaintained
command mode can be
set. All control functions can be
implemented using the 3UF50 basic
unit. If more than four inputs and four
outputs are required, an additional
eight inputs and four outputs can be
fitted by using an extension module.
Cost reduction by pre-defined
control functions
In the SIMOCODE-DP, all necessary
interlocking requirements for the
relevant control function (e.g. with
encoders the undelayed deactivation
of the motor in case of an operation of
the limit or torque switch) are implemented.
This offers major advantages:
• Reducing the demands put on the
user program in the programmable
controller, i.e. fast planning, fewer
possibilities for errors, shorter
program cycle times
• Time-critical functions of the
motor feeder are independent of
the signal process time in the
automation level and on the
communication system.
In addition, run time checks can be set
for the start or stop of motors and for
the slide valve control functions in
between the limits.
Safety by operator enable and
manual/automatic switch-over
In the automatic mode, control
commands (e.g. ON, OFF) are transmitted
to SIMOCODE-DP via the bus.
Control commands from the switchgear
cubicle (e.g. of the operating
module) or from the local control
station are only possible in this
operating mode if the corresponding
operator enable commands have been
set.

If the automatic level switches to
manual operation, or if local control is
activated by means of a local manual/
automatic key switch, the bus control
commands are ignored and the feeder
can now be exclusively controlled via
the operating module or using the local
control station.
Reduction of failure times by
autonomous operation
In case of system failures on the
communication system, SIMOCODE-
DP automatically switches to manual
mode.
When this occurs, the load is either
switched OFF or the operating state is
maintained. Further control is possible
using the manual mode.
Downtimes in case of failures in the
automation and communication level
are considerably reduced: The process
can still be safely continued locally due
to the autonomous structure of the
SIMOCODE-DP.
The process can be resumed however
surely by the self-sufficient structure of
the system SIMOCODE-DP locally.
It means self-sufficient that all
protective relay for motor and control
functions are processed independently
of the automation level in the
SIMOCODE-DP.
Flexibility due to decentralised
signal logic-, delays- and
conditioning
The great flexibility of the SIMOCODE-
DP system is especially characterised
by the integrated:
• 3 truth tables
(3 inputs with 1 output each)
• 1 truth table
(5 inputs with 2 outputs)
• 2 timers
(0.5 s...60 min; output behavior:
ON delay, OFF delay, fleeting
NO contact)
• 2 counters
(0...65535)
• 4 elements of signal processing
– Inverted level without memory
– Rising edge with memory
– Falling edge with memory
• Signal conditioning
– 3 flashing modules
– 3 flickering modules.
• 2 elements of non-resetting
onvoltage failure
The inputs and outputs of the system
can be assigned to predefined control
functions as well as to the truth tables,
timers and counters. Thus, a flexible
use of the predefined control functions
is possible.
The make/break contact behavior of
the outputs is set by the signal
processing modules.
Selective start of the system
After a mains failure, the motor feeders
can be restarted using time-grading.
This makes a fast and selective start of
the system possible.

Control and Signalling

Extensive Diagnostics
SIMOCODE-DP offers a large amount
of operational and statistical data on
the feeder, which is available to the
user for visualisation and diagnostic
purposes.
This data can be accessed:
• directly at the switchboard via the
LED display of the hand-held-unit
plugged into the basic unit or
operator panel, or via a PC with
Win-SIMOCODE-DP/Smart.
• via PROFIBUS-DP. The data can be
read by the user program and it can
be transferred to a corresponding
operator communication and
monitoring system. Thus, the various
operational and statistical information
can be displayed in the control room
• over PROFIBUS-DPV1 with a
communications processor which
were in the PC/PU and the software
Win-SIMOCODE-DP/Professional
Always informed as to the current
operating state
SIMOCODE-DP continuously informs
the process engineer about the current
operating state:
• actual phase current in %
• ON/OFF
• Anti-clockwise, clockwise LEFT/
RIGHT
• Fast, slow
• Slide open, closed, moving
• Warning
• Fault.
Reduction of failures by the
signalling of critical operating
states
The settable current limits inform the
process engineer about critical states
in the system. For example, a current
which is below the lower current limit
setting could mean a broken conveyor
belt for example. The overloading of a
mixing machine for example can be
quickly detected by the display of
‘upper current limit exceeded.’ To avoid
an overload trip of the machine, the
process engineer can take precise
steps to change the working process,
such as reducing the amount of
material in the mixer.
Display of other critical operating
states:
• Current imbalance
• Overload warning/trip
• Thermistor motor protection
warning/trip
• Earth fault warning/trip
• Locked rotor protection
• Warning/trip upper/lower current
limit response.
Reduction of maintenance times
Maintenance intervals can be
increased, as all statistical data relating
to the condition of a particular feeder is
transmitted from the SIMOCODE-DP to
the PLC. SIMOCODE-DP registers the
number of starts and the number of
overload trips, counts the operating
hours and calculates the current in %
of the last trip. All data is stored in a
non-volatile memory in SIMOCODE-DP.
Analogue Current display
For display of analogue current value
through a display device on the panel
door; the SIMOCODE-DP system is
provided with an external current
transformer (range 0.25 A-820 A/1A).
With this it is also possible for the
systemselector to inform about the
actual current flowing in the motor
feeder.
Self-monitoring
The correct function of the
SIMOCODE-DP processor is
permanently monitored. If there is a
fault, SIMOCODE-DP switches the
load to the adjustement, safe state
(OFF, or maintain operating state -
monostable or bistable behavior).
Also testable ‘in action’
This function gives SIMOCODE-DP
additional safety and better monitoring
features.
The operation of SIMOCODE-DP can
be checked during running – without
switching off of the motor. This saves
time and avoids unnecessary
interruptions of the operation.

possibility to use optical link modules
so that the data transmission would be
effected via plastic or glass fibre optic
cables.

Communication –
PROFIBUS-DPV1
The PROFIBUS-DP standard has been
extended around acyclic reading and
writing from data and with PROFIBUS-
DPV1 this can be achieved. Acyclic
reading and writing means for
SIMOCODE-DP, that from a central
workstation over PROFIBUS-DPV1
with a PC or PU fitted with
communicatios processor and the
software Win-SIMOCODE-DP/
Professional all control, diagnosis,
test and parameter data can be
read and written. The PROFIBUS-DPV1
is a secondary protocol for the
PROFIBUS-DP, and it does not
require additional lines or interfaces.

The communication processors
SIMOCODE-DP can work with any
standard DP master which is able to
read GSD files and which is capable
of processing the following amounts
of data:
• Control data 1 or 4 byte cyclic from
the DP master to SIMOCODE-DP
• Signalling data 1/4/12 byte cyclic
from SIMOCODE-DP to the DP
master
• Diagnosis data 20 byte acyclic from
SIMOCODE-DP to the DP master
• Parameter data 213 byte.
For acyclic reading and writing from
data the communication processor
must be able the standard extension
PROFIBUS-DPV1.
Bus system expandable
If no bus system is applicable at the
today‘s point in time, then can be
easily re-tooled this later. Because
SIMOCODE-DP processes all
protective relay for motor and control
functions independently of the
automation level.
Naturally also SIMOCODE-DP is
applicable as self-sufficient protective
realy for motor and controller without
PROFIBUS-DP genereally.

Integrating many slaves using only
one software
The integration of SIMOCODE-DP into
a PROFIBUS-DP network is easily
achieved via the parameterising and
service programme of COM
PROFIBUS Windows 3.1 or of
SIMATIC S7: Step 7 Windows 95.
Call up the parameterisation and
service program COM PROFIBUS -
open the master system under File
„New“ and add the individual slaves
e.g. the SIMOCODE-DP, the
PROFIBUS-DP interface for the circuitbreaker
or the micro master -
everything with just one software.
Double-click on the SIMOCODE-DP
icon and now the required parameters
for the motor feeder can be set.
SIMOCODE-DP – Online
Parametrization
Now the user can parameterize
SIMOCODE-DP „Online“ from a
central workstation through
PROFIBUS-DP.
So, what is meant by „Online“?
Previously it was possible to transfer
the slave parameters through
PROFIBUS-DP only in the start-up
phase of the communication processor.
But now exists the possibility that
besides normal cyclic data exchange,
acyclic reading and writing of
parameters is also possible. This
means now SIMOCODE-DP can be
parameterized, controlled, observed
and tested from a central project
engineering workstation by using Win-
SIMOCODE-DP/Professional software.
This central project engineering
workstation should be equipped with a
personnel computer (PC) or a
programming unit (PU) with integrated
PROFIBUS-DP communication
processor. Another possibility is to use
a Siemens PU, with integrated MPI
interface and access the PROFIBUS-
DP directly.
Reduced comissioning time
Now its not required to run around
from switch room and parametrize the
motor feeders. All SIMOCODE-DP
connected to PROFIBUS-DP can be
parametrized from a central place.
Moreover all parameters can also be
read and written by that.
Increased system availability
In the past changing of parameters
meant system deadlock. With Win-
SIMOCODE-DP/Professional the
parameters in SIMOCODE-DP can be
modified „Online“ through PROFIBUS-
DP – wihtout bringing the system to a
halt.

„Totally Integrated“ in SIMATIC S7,
C7, M7, PCS7 – OM-SIMOCODE-DP
Win-SIMOCODE-DP/Professional is
„Totally Integrated“ in SIMATIC S7/C7/
M7 as well as PCS7. The call is made
by STEP 7 from HW-Config. The OM-
SIMOCODE-DP therby implements
the data interface.
This results in a unique possibility; that
only with one software package one
can write the PLC user programme,
configure PROFIBUS-DP and
parameterize SIMOCODE-DP 3UF5 –
the communication capable motor
protection and control device. Use of
different complex software packages is
omitted thereby.
Totally Integrated in SIMATIC S7/M7/C7/PCS7
A plus for commisioning
Another advantage of the SIMOCODE-
DP system is that a motor feeder can
be tested during the commisioning
stage with the Win-SIMOCODE-DP/
Professional software. This means,
there lies a possibility, that one can
switch on and off from a central
workstation and also set the Testbits
and enquire about the device state.

Price Advantage with SIMOCODE-DP
Figure 1 shows the configuration of a
typical communications-capable motor
feeder with overload relay, thermistor
motor protection device, earth fault
detection, current value transmission
via A/D converters and a decentralised
peripheral system for the bus
connection.
Figures 2 and Figure 3 show the motor
branch of the future.
Reduced number of products
cover the entire range
For the complete control and
monitoring including connection to the
PROFIBUS-DP, only SIMOCODE-DP is
required. This means that no additional
overload relays, thermistor evaluation
devices etc. need to be installed.
Reduction of the scope of wiring
between field and control level
Communication between the field
level and the higher automation level
(PLC or process control system DCS)
is normally implemented via coupling
devices and point-to-point connections
to input and output modules of the
PLC or DCS. With the application of
SIMOCODE-DP, the scope of wiring is
reduced to a minimum - A two-wire
PROFIBUS-DP cable for up to 100
motor feeder; Coupling devices and
input/output modules, cable gallery are
not required.
Reduction in wiring costs in
the field level
In the case of the reverser starter
(figure 3) no electrical interlocking is
required, and no time-delay relay which
prevents a direct switch-over from
clockwise to anti-clockwise rotation is
necessary. Everything is implemented
with SIMOCODE-DP.␣ The only thing
required is to set the desired switchover

Modular Device Configuration
The modular configuration of the
SIMOCODE-DP system means that it
can be used as a protection and
control device for feeders. The system
consists of the following components:

four outputs implements all protection
and control functions autonomously,
and provides connection to the
PROFIBUS-DP.␣ The four inputs are fed
by the internal 24 V DC power supply.
The extension module, the operating
module, the manual operating device
or the PC can be connected via the
system interface. The basic unit is
produced with three different control
supply voltage
(24 V DC, 115 V AC, 230 V AC).

provides eight inputs and four outputs
to the system. The device itself is fed
by the basic unit. The eight inputs
must be connected to an external
voltage supply. Here, there are three
different voltage versions (24 V DC,
115 V AC, 230 V AC). The connection to
the basic unit and the connection to
the operating module, to the manual
operating device or to the PC is via the
system interface.

cubicle. Can be connected to the basic
unit and to the extension module.
Power supply from the basic unit.
Connection possibilities for the manual
operating device or PC. Installation in
the front panel or in the IP 54 cubicle
door.
Three buttons can be freely
parameterised. Six signalling LEDs
can be freely parameterised.

Bus terminal/bus termination
modules
If the PROFIBUS-DP is connected to
the basic unit, the standard 9-pole Sub-
D plugs with built-in bus terminating
resistor can be used. Especially for the
application of SIMOCODE-DP in Motor
Control Centers (MCC drawout unit
design) there is a bus termination
module with built-in power supply. This
guarantees that even the last unit in
the bus can be removed without any
impairment of the data flow.
Operating manual
A manual for the SIMOCODE-DP
system is available which describes
each detail of the functionality of
SIMOCODE-DP. It is intended as an aid
for project planning and system startup
and it features a comprehensive
description of the PROFIBUS-DP
communications interface and project
examples.

SIVACON – The Communications-Capable
Low-Voltage Switchgear
As well as the communicationscapable
3WN6 circuit-breakers and
AS-Interface modules, SIMOCODE-DP
now provides another communications
module for low-voltage switchgear.
SIMOCODE-DP can be used in
SIVACON® for the control of all
feeders in both fixed and drawout
design.
High availability - no problem with
SIVACON drawout design
SIVACON drawout design enables the
system operator to adapt quickly to
changing system requirements.
With the integration of SIMOCODE-DP
directly into the drawout units, a clear
connection to the feeder and the
corresponding SIMOCODE-DP is
reached. A replacement of drawout
units is possible without interruption of
the bus connection.
Technical configuration of the
SIVACON switchgear with
SIMOCODE-DP
The 3UF52 operating module is always
accessible from the front and is
situated in the front panel of the
relevant drawout unit.
The 3UF50 basic unit with the integrated
current transformers is built into
the inside of the drawout units.
Each feeder can be adjusted and
controlled autonomously at the
switchboard by connecting the manual
operating device or a PC with the WIN-
SIMOCODE-DP software to the
operating module integrated into the
front panel. In addition, all operation,
diagnostic and statistical data
determined by SIMOCODE-DP can be
read.
