8SIPART DR22 6DR2210
C79000-G7476-C154-03
DSubject to change
The user’s guide has been compiled with great care. However, it may be necessary within
the scope of product care to make changes to the product and its operation without prior
notice which are not contained in this user’s guide. We are not liable for any costs ensuing
for this reason.
1.2 Range of Application
The SIPART DR22 is a digitally operating device in the top class range. Its program memory
contains a large number of prepared function blocks for calculating, controlling, regulating in
technical processes which the user can implement without programming knowledge and
additional tools.
In addition a robust adaptation procedure is available in this device which makes it much easier
to commission even critical controlled systems. The controller determines the optimized control
parameters independently on request without the user being expected to have any prior
knowledge of how the control loop may respond. The applied procedure is suitable for systems
with compensation and aperiodic transient behavior; even greater dead times are taken into
account.
For more complicated applications the fixed connection of the individual functions can be
canceled in the input range and replaced by a free structuring. The user can easily add extra
analog function blocks and connect them to each other and to the interfaces of the input range
with the software. This achieves optimum adaptation even to complex problems.
The named programming possibilities guarantee a great flexibility in the use of the controller
and allow fast, easy adapting of the device to the problem so that the SIPART DR22 can be
used universally for control jobs in processing engineering, e.g. as
-- fixed setpoint controller for one, two or three-component control, optionally with two
setpoints
-- DDC fixed setpoint controller for one-, two- or three-component control
-- follow-up controller (synchronized controller, SPC controller) with internal/external switching
-- fixed or commanded ratio controller with Internal/External switching
-- cascade controller (double controller)
-- ratio-cascade controller (double controller)
-- override controller with Min or Max selection of the manipulated variable (double controller)
-- double controller with two independent control channels
The extensive hardware equipment of the instrument by which numerous interfaces are
available for connecting the field cables is of advantage for the universal utilization. The
instrument can also be connected to master systems via a plug-in serial interface or operated
and monitored centrally by a Personal Computer.
The SIPART DR22 can be used alternatively as a continuous controller with a current output
signal or as a three-position step controller for controlling electric motor drives without changing
the hardware equipment.

Manual 1 Technical Description
1.3 Design (Hardware)
SIPART DR22 6DR2210
C79000-G7476-C154-03 9
1.3 Design (Hardware)
The process controller SIPART DR22 has a modular structure and is therefore maintenance
friendly and easy to convert and retrofit. Other signal convertors can be installed in the gener-
ously equipped, fully functional standard controller to expand the range of application. These
modules are inserted in backplane slots of the enclosed instrument (Fig. 1-2, page 11).
The standard controller consists of
-- the front module with the control and display elements
-- the main board with CPU and terminal strips
-- the plastic casing with an interface board
-- the power supply unit.
The electrical connections between the modules are made by an interface board screwed into
the casing. The main board is pushed into rear slot 1 and locked. It holds a 10-pin and a 14-pin
terminal strip to which all inputs and outputs of the standard controller are connected. Five other
slots can be equipped with option modules if the number of terminals to the process available in
the standard controller are not sufficient for the planned task.
The standard controller always has three permanently installed analog inputs (AE) with elec-
tronic potential isolation which can be wired alternatively with standardized voltage signals
(0/0.2 to 1 V or 0/2 to 10 V) or current signals (0/4 to 20 mA). There are also four digital inputs
(BE, 0/24 V) and eight digital outputs (BA, 0/24 V, 50 mA) which can be used for different func-
tions depending on the configuration.
The SIPART DR22 also has three analog outputs (AA) which can all supply a current signal
from 0 to 20 mA or 4 to 20 mA and be assigned to different variables.
A short-circuit-proof L+--output (DC 24 V, 100 mA) is available for supplying transmitters.
The power supply unit is located in a fully enclosed metal casing and is screwed tightly to the
plastic casing of the controller. This power supply is available in two different versions so that
two types of SIPART DR22 are available:
6DR2210-4 for power supply connection UC 24 V
6DR2210-5 for power supply connection AC 230 V, switchable to AC 115 V
Many applications can be implemented with the three permanently available analog inputs of
the standard controller alone. Two additional input modules can be inserted in slots 2 and 3 for
complex jobs or for the connection of other input signals. These input modules are available in
addition to for processing normalized current and voltage signals for the direct connection of
resistance thermometers Pt100 and all common thermocouples and resistance sensors or
potentiometers. In addition a module with 3 analog inputs (equipment as in the standard
controller) can be inserted in slots 5 and 6. This increases the number of inputs to a total of 11.
Slot 4 serves to accommodate an interface module (SES) with V.28-point-pointoutput or
SIPART bus interface for serial communication with a master system. A PROFIBUS interface
module can be equipped optionally here.

C79000-G7476-C154-03
1.4 Function principle
1.4.1 Standard controller
The standard controller consists of three function blocks:
-- Power supply unit
-- Front module
-- Main board
Power supply unit
Primary clocked power supply plug with high efficiency for AC 115/230 V (switchable) or for UC
24 V. It generates the secondary internal supply voltages +24 V and +5 V from the power
supply. The metal body is mounted on PE conductors (protection class I). The power supply
and internal supply voltages are isolated from each other by safe separation by a protective
shield. The internal supply voltages are functional extra-low voltages due to overvoltage cutoff
in the event of an error. Since no other voltages are generated in the instrument, these
statements apply for all field signal cables (used standards, see chapter 1.6, page 127). A total of
450 mA are available for the outputs L+, AA and BA due to the design for a high power output.
Front module
The front module contains the control and display elements and the appropriate trigger compo-
nents for the displays.
All display elements are designed in LED technology which provides a longer service life and
higher light density as well as a good viewing angle. The control elements are short-stroke
switches with a tangible ”pressure point” and high return force.
Main board
The main board contains the field signal conditioning of the standard controller, the CPU
(Central Processing Unit) and the connections (through the interface board) to the module slots.
The field signals are fed through protective circuits for external static or dynamic overvoltages
and then adapted to the signal levels of the CPU by the appropriate circuits. This adaptation is
performed for the analog inputs, the analog outputs and the digital outputs by modern thick-film
circuits.
The microcontroller used has integrated AD- and DA converters and operates with 32k battery-
backed RAM. The user-specific configuration is stored in an user program memory with a serial
4k EEPROM. When replacing the main board the user memory can be plugged from the old
onto the new module. The whole CPU is designed in C-MOS technology.
A process image is generated at the start of every routine. The analog and digital inputs and
actuation of the front buttons is included and the process variables received from the serial
interface are accepted. All calculations are made with these input signals according to the
configured functions. Then the data are output to the display elements, the analog outputs and
the digital outputs as well as storage of the calculated variables on standby for the serial
interface transmitter. The interface traffic runs in interrupt mode.

1.4.2 Description of the option modules
SIPART DR22 6DR2210
C79000-G7476-C154-03 13
A large number of prepared functions for controlling processing plants as well as machines and
apparatus is stored in the set value memory of the SIPART DR22. The user programs the
instrument himself by selecting the desired functions by setting structure switches. The total
functioning of the instrument is given by the combination of the individual structure switches.
Programming knowledge is not necessary for the settings. All settings are made without an
additional programming unit exclusively through the front panel of the SIPART DR22 or through
the serial interface. The job-specific program written in this way is saved in the non-volatile user
program memory.

C79000-G7476-C154-03
6DR2800-8J I/U module
DInput variables current 0/4 to 20 mA or voltage 0/0.2 to 1 V or 0/2 to 10 V
The input amplifier of the module is designed as a differentiating amplifier with jumperable gain
for 0 to 1 V or 0 to 10 V input signal. For current input signals the 49.9 Ω0.1 % impedance is
switched on by plug-in bridges on the module. The start value 0 mA or 4 mA or 0 V or 0.2 V
(2 V) is defined by configuration in the standard controller. The differentiating amplifier is
designed for common mode voltages up to 10 V and has a high common mode suppression.
As a result it is possible to connect the current inputs in series as for electrical isolation when
they have common ground. At voltage inputs this circuit technique makes it possible to
suppress the voltage dips on the ground rail by two--pole wiring on non floating voltage supplies.
We refer to an electronic potential isolation.
6DR2800-8R R module
DInput for resistance or current potentiometer
Potentiometers with rated values of 80 Ωto 1200 Ωcan be connected as resistance
potentiometers. A constant current of Is = 5 mA is fed to the potentiometer wiper. The wiper
resistance is therefore not included in the measurement. Resistances are switched parallel to
the potentiometer by a slide switch on the module and a rough range selection made. Range
start and end are set with the two adjusting pots on the back of the module.
This fine adjustment can be made by the displays on the front module (with the appropriate
structuring). For adjustment with a remote measuring instrument, the analog output can be as-
signed to the appropriate input.
The external wiring must be changed for resistance potentiometers which cannot withstand the
5 mA wiper current or which have a rated resistance >1kΩ. The constant current is then not
fed through the wiper but through the whole resistance network of the potentiometer. A voltage
divider measurement is now made through the wiper. Coarse adjustment is made by a remote
parallel resistor to the resistance potentiometer.
This module can also be used as a current input with adjustable range start and full scale. The
load is 49.9 Ωand is referenced to ground.
6DR2800-8V UNI module
DDirect connection of thermocouple or Pt100 sensors, resistance of mV transmitters
Measured value sensors such as thermocouples (TC), resistance thermometers Pt100 (RTD),
resistance potentiometers (R) or voltage transmitters in the mV range can be connected di-
rectly. The measuring variable is selected by configuring the controller in the HdeF level
(AE4/AE5); the range and the other parameters are set in the CAE4/CAE5 menu. The sensor-
specific characteristics (linearization) for thermocouples and Pt100 resistance thermometers are
stored in the contoller’s program memory and are automatically taken into account. No settings
need to be made on the module itself.

SIPART DR22 6DR2210
C79000-G7476-C154-03 15
The signal lines are connected by a plug terminal block with screw terminals. When using ther-
mocouples with internal reference junction terminal, this terminal block must be replaced by the
terminal 6DR2805-8A. With the measuring for TC, internal connector 6DR2805-8J in place of
the terminal block, the measuring range of the direct input (0/20 to 100 mV) can be extended to
0/2upto10Vor0/4upto20mA.
The UNI module operates with an AD converter with 18 bit resolution. The measuring inputs
and ground of the standard controller are electrically isolated with a permissible common mode
voltage of 50 V UC.
6DR2805-8A reference junction terminal
DTerminal with internal reference junction terminal for thermocouples
This terminal is used in connection with the UNI module for temperature measuring with ther-
mocouples at an internal reference junction terminal. It consists of a temperature sensor which
is pre-
assembled on a terminal block and plated to avoid mechanical damage.
6DR2805-8J measuring for TC, internal connector
Dmeasuring for TC, internal connector for current 0/4 to 20 mA or voltage 0/2 to 10 V
The measuring for TC, internal connector is used in connection with the UNI module to
measure current orvoltage. The input variable is reduced to 0/20 to 100 mV by a voltage divider
or shunt resistors in the measuring for TC, internal connector.
Wiper resistors with 250 Ωor 50 Ωare available optionally at 2 different terminals for 0/4 to
20 mA signals.
The electrical isolation of the UNI module is retained even when the measuring for TC, internal
connector is used.
6DR2801-8D Module with 2 BA relays
DDigital output module with 2 relay contacts
To convert 2 digital outputs to relay contacts up to 35 V UC.
This module is equipped with 2 relays whose switching contacts have potential free outputs.
The RC combinations of the spark quenching elements are respectively parallel to the rest and
working contacts.
In AC consumers with low power the current flowing through the capacitor of the spark
quenching element when the contact is open may interfere (e.g. the hold current of some
switching elements is not exceeded). In this case the capacitors (1 μF) must be removed and
replaced with low capacitance capacitors.
The 68 V suppressor diodes parallel to the capacitors act additionally to reduce the induced
voltage.

!WARNING
The relays used on the digital output module are designed for a
maximum rating up to UC 35 V. The same applies for the air and creep
lines on the circuit board. Higher voltages may therefore only be
switched through appropriately approved series connected circuit
elements under observance of the technical data and the pertinent
safety regulations.
6DR2801-8E Module with 2 BE and 4 BA
DDigital signal module with 2 digital inputs and 4 digital outputs
The module serves to extend the digital inputs and digital outputs already existing in the stan-
dard controller.
The inputs are designed for the 24 V logic and are non-floating. The functions are assigned to
the inputs and outputs by the configuration of the controller.
The digital outputs are short-circuit-proof and can drive commercially available relays or the
interface relays 6DR2804--8A/8B directly.
6DR2801-8C Module with 5 BE
DDigital input module with 5 digital inputs
The module serves to extend the digital inputs already existing in the standard controller.
The inputs are designed for the 24 V logic and are non-floating. The function is assigned to the
input by the configuration of the controller.
6DR2802-8A Analog output module with y-hold function
For auxiliary control device function when servicing and for extending the analog outputs AA1 to
AA3 existing in the standard controller.
Can be inserted in slot 5/6, S22/S23=4 to be set in the structure mode StrS,
Start value of the outputs S72/S249 can be set in StrS.
The yholdmodule contains a microprocessor which maintains serial data communication with the
processor on the main board through the Rxd/Txd lines. The processor feeds the U/Iconverter
and the CPU fault message output St through its analog output. The module can be externally
supplied through an auxiliary voltage input which is OR--linked with the controller power supply.
The analog output of the module is freely available.
-- yhold-function
If data communication to the yhold processor is interrupted, the analog output receives its last
value. The processor reads the current variable first when data traffic is recovered. The out-
put current is maintained if:

-- the self diagnostics of the CPU (see chapter 1.4.3, page 20) responds.
-- the supply voltage of the SIPART DR22 fails and the yhold-module is powered externally.
-- all modules except the power supply unit are removed (if the yhold module is powered
externally).

In this way it is possible to perform all maintenance work right up to replacing the instrument
whilst maintaining the controller controlled variable.
Handling during module replacement, see chapter 5 ”Maintenance”.

and in slot 6: AA4, AA5, AA6 BE10, BE11, BE12
6DR2803-8P Serial interface PROFIBUS-DP
The module 6DR2803-8P is a PROFIBUS-DP interface module with RS 485 driver and electri-
cal isolation to the controller. It operates as an intelligent converter module and adapts the pri-
vate SIPART to the open PROFIBUS-DP protocol.
This optional card can be inserted in all SIPART-DR controllers in slot 4. The following settings
must be made with the appropriate configurations for the serial interface:
-- Interface on
-- Even parity
-- LRC without
-- Baud rate 9600
-- Parameters/process values writable (as desired)
-- Station number according to selection 0 to 125
Make sure that the station number is not assigned double on the bus. The PROFIBUS module
serves to connect the SIPART controllers to a master system for control and monitoring.
In addition the parameters and configuring switches of the controller can be read and written.
Up to 32 process variables can be selected and read out cyclically by configuration of the
PROFIBUS module.
