1.2 Range of Application
Manual1 Technical Description
D Subject 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.

C79000-G7476-C154-03
Manual 1 Technical Description
1.3 Design (Hardware)
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 generously 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 electronic 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 functions 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.

1.4 Function principle
1.4.1 Standard controller
Manual1 Technical Description
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 components 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 batterybacked 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.

Manual 1 Technical Description
1.4.2 Description of the option modules
1.4 Function principle
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.

Manual1 Technical Description
6DR2800-8J I/U module
D Input 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 Ω 0.1 % 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
D Input for resistance or current potentiometer
Potentiometers with rated values of 80 Ω to 1200 Ω can 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 assigned 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 Ω and is referenced to ground.
6DR2800-8V UNI module
D Direct 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 directly. 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 sensorspecific 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.

1.4 Function principle
The signal lines are connected by a plug terminal block with screw terminals. When using thermocouples 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
D Terminal with internal reference junction terminal for thermocouples
This terminal is used in connection with the UNI module for temperature measuring with thermocouples at an internal reference junction terminal. It consists of a temperature sensor which
is preassembled on a terminal block and plated to avoid mechanical damage.
6DR2805-8J measuring for TC, internal connector
D measuring 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 Ω or 50 Ω are 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
D Digital 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.

To convert 2 or 4 binary outputs to relay contacts up to 230 V UC.
The module can be snapped onto a mounting rail on the back of the controller. The mounting
rail is delivered with the interface relay module.
One or two relay modules with 2 relays each are installed depending on the version. Every relay
has a switching contact with spark quenching in both switching branches. In AC consumers with
a very low power, the current flowing (e.g. hold current in contactors) through the spark quenching capacitor (33nF) when the contact is open interferes. In this case they should be replaced
by capacitors of the same construction type, voltage strength and lower value.
The switching contact is fed to the plug terminals with 3 poles so that rest and working circuits
can be switched. The relays can be controlled directly from the controller’s digital outputs by
external wiring.

1.4.3 CPU self-diagnostics
Manual1 Technical Description
!
WARNING
The relays used on the interface relay module are designed for a
maximum rating of AC 250 V in overvoltage class III and
contamination factor 2 according to DIN EN 61010 Part 1.
The same applies for the air and creep lines on the circuit board.
Resonance increases up to twice the rated operating voltage may
occur when phase shift motors are controlled. These voltages are
available at the open relay contact. Therefore such motors may only
be controlled under observance of the technical data and the
pertinent safety conditions via approved switching elements.
1.4.3 CPU self-diagnostics
The CPU runs safety diagnostics routines which either can only after a reset or cyclically. The
CPU is familiar with two different types of reset.
-- Power on reset
Power-On-Reset always takes place when the 5-V supply drops below 4.45 V, i.e. the power
supply is interrupted for longer than specified in the technical data.
All parameters and configurations are reloaded from the user program memory into the
RAM.
At S100 = 1 the digital x-display flashes as indication after a Power-On-Reset, it is
acknowledged by the Shift key (12).
Flashing is suppressed by S100 = 0.
-- Watch dog reset
When a watch-dog-reset occurs the parameters and configurations from the user program
memory are reloaded into the RAM. The current process variables and the status signals are
read out of the RAM for further processing.
There are no flashing signals on the front module.
CPU-tESt appears in the digital displays dd1 and dd2 for a maximum 5 s after every reset.
Every error detected by the self-diagnostics leads to a flashing error message on the digital displays dd1 and dd2 with defined states of the analog and digital outputs. The fault message output St
of the y
module becomes low. The reactions listed in the table are only possible of
hold
course (since this is a self-test) if the errors occur in such a way that the appropriate outputs or
the front module can still be controlled properly or the outputs themselves are still functioning.
There are other error messages for the input range which indicate defective structurings within
this range (see chapter 1.5.6 ”Error messages”, page 99).
In addition error messages are output in the adaptation (see chapter 3.3.2
”Parameterization mode AdAP”, page 173).
The digital displays flash in the case of error messages.

1.5 Functional description of the structure switches
1.5.1 Analog input signal processing permanently connected
Manual1 Technical Description
1.5 Functional description of the structure switches
(S0 to S107, S200 to S268)
In the factory setting (setting when the device is delivered) most of the structure switches are
set to 0. This corresponds to the most usual setting of the individual functions so that only few
structure switches need to be set selectively during commissioning. However, it is recommendable to compare the individual structure switch settings with the task.
With structure switch S0 the user program can be identified by a number from 1 to 254 in the
structuring mode Strs. The setting 0 corresponds to the factory setting and is regenerated automatically in the APSt function (All Preset). All changes in parameters or structures in relation to
the factory setting automatically set S0 from 0 to 1.
The structure switches S1 and S2 are fundamentally significant. With S1 the controller type is
set and thus the processing of command variable, main controlled variable and auxiliary controlled variables up to control difference generation determined. With S2 the controller output
structure is set and thus the processing of the automatic-, manual-, safety- and follow--up variables as well as the manipulated variable output determined as a K- or S-output.
1.5.1 Analog input signal processing permanently connected
(S3 to S21, S200 to 205)
In the structure switch setting S4=0 the analog input range is permanently connected
(see figure 1-5, page 24). With S4=1 the permanent connection is canceled and converted into
a freely connectable input range (see chapter 1.5.2, page 25).
Every one of the maximum 11 analog inputs is fed through an AD converter which performs the
50 or 60 Hz interference suppression by averaging over 20 or 16 2/3 ms. After this the signal
range 0 to 20 mA or 4 to 20 mA is normalized to 0 to 100% calculated value per channel with
S5 to S9 or S200 to S205.
At the same time it is decided with S5 to S9 or S200 to S205 whether operation is to take place
with or without range monitoring (transmitter fault). The monitor signals per channel on dropping
below --2.5 % or exceeding +106.25 % with a hysteresis of 0.25 % to the digital x and w display.
By an OR link of all single messages the group transmitter fault MUF is formed which can be
assigned to the digital outputs and negated optionally (see chapter 1.5.8, page 121). Only the
analog inputs selected with the transmitter fault monitor are monitored, displayed on the front
panel (the appropriate position stays dark in the case of analog inputs not selected with transmitter fault) and signaled with the OR link. The error message is acknowledged with the Shift
key (12). The fault message signal via the OR link is available until the appropriate analog inputs are back in the working range.
After the range monitoring the 11 analog inputs are fed through a 1st order filter which can be
set by the parameters tF1 to tFb in the range of oFF, 0.1 to 1000 s in the parameterization
mode onPA. The factory setting is 1 s.
With S10 to S14 or S206 to S211 every channel can now be root extracted optionally. After root
extraction, the 11 analog inputs are available for further processing as AEA1 to AEbA.

1.5 Functional description of the structure switches
1.5.2 Analog input signal processing freely connected (S4 = 1)
The structure switch setting S4=1 cancels the permanent connection at S4=0 in the analog input range and replaces it with a freely connectable input range. The freely connectable input
range basically represents a multifunctional unit, configuring takes place according to the same
rules.
Up to the outputs AE1A to AEbA (AE11A), the signal processing is identical to that described in
chapter 1.5.1, page 22. The function inputs FE1 to FE12 also operate in the same way with the
difference that FE5 (follow-up input) and FE6 (position feedback input) can be used in parallel
and with the difference that FE5 (follow--up input) and FE6 (position feedback input) can be
used in parallel and connected with different signals.
Nine different function blocks which occur with different frequency can now be connected
absolutely freely between the outputs AE1A to AEbA and the function inputs FE1 to FE12. The
outputs AE1A to AEbA represent data sources whilst the function inputs FE1 to FE12 are data
sources. Parallel to the outputs, 15 connectable linear parameters are arranged with a setting
range of -1.999 to 19.999 (corresponding to -199.9 % to 1999.9 %), a number of normal
constants as well as other variables gained from the controller as data source.
The function blocks have a different number of inputs (data sinks) and 1 output each (data
source) depending on the function depth.
The function blocks ”function transmitter” and ”correction computer” have assigned parameters
which can be set in the structuring mode oFPA. The connectable parameters P1 to P15 are set
in the parameterization mode onPA.
By structuring on the front module the necessary functions are selected or defined (structuring
mode FdEF), connected (structuring mode FCon) and correctly positioned in time in the cycle
(structuring mode FPoS), see chapter 3.3.7, page 201 to 3.3.9, page 205. Connection is absolutely free, i.e. any data source can be connected with any data sink. The operating effort is
minimized by fading the data sources and sinks from undefined function blocks. In addition the
data sinks which are not obliagatory for a function are pre--occupied by constants which can be
overwritten. The inputs pre--occupied with ncon (not connected) are absolutely essential for the
function and must be connected. This very variable connection facility in the analog input range
also enables complex control tasks to be solved.
No distinction is made between analog and digital signals. Digital inputs have a threshold value
of 0.5. Digital outputs supply a value of 0 % (0) or 100 % (1).

assignment of inputs 0 and 1 respectively. The preset E3=E4=0, E5=1 gives A = E1×E2.
-- Typical process-technical applications are dosing or evaluation (E1×E2), range fade-outs
(E1×E2+E3) or differentiations (E3 - E4).

Figure 1-8 Function block function transmitter
The function transmitter assigns every value of the input variable E in the range from -10 % to
+110 % an output variable A in the range from -199,9 % to +199,9 % with the function entered
by the user: A = f(E). The function is entered by the parameters ”vertex value 1 to 13” for -10 %
to +110 % of E in intervals of 10 %. Parabolae are set by the computing program between
these vertex values which interlink tangentially the vertex values so that a constant function is
produced. The vertex values at -10 % and +110 % of E are required for the overflow. The last
rise remains constant in the case of further overmodulation of E. When used as a linearizer for
the displays, the linearization function is entered by the 13 vertex values so that the series
circuiting of the sensor function gives a linear equation with the linearization function
(see chapter 1.5.4, figure 1-20 to figure 1-23, page 46).

The rooted signal of the active pressure must be applied at input c**.1. The measuring ranges
are normalized to the calculation state with the parameters PA, PE, tA, tE (correction quotients
start/end for pressure and temperature).
Range of Application
The correction computer is used to calculate the flow of gases from the active pressure Δp
depending on pressure and temperature. The medium must be in pure phase, i.e. so that no
liquid separations may take place. This should be noted particularly for gases close to the
saturation point.

Errors due to fluctuating status variables of the medium (pressure, temperature) are corrected
by the flow correction computer here.
