1 Functions
The ZDUE-GPRS-PLUS-VI is a meter data transmission device. It is used
for remote reading and remote monitoring of electricity meters as well as
meters for other media.
Data transmission for remote reading and remote monitoring can take place
via:
one of the common GSM networks using the Circuit Switched Data
service (CSD)
one of the common GSM networks using the General Packet Radio
Service (GPRS)
In the following, the ZDUE-GPRS-PLUS-VI in CSD mode will be described
first. Different or supplementary functions in GPRS mode are described in
chapter 7.
With the ZDUE-GPRS-PLUS-VI, data transmission for remote reading and
remote monitoring can take place via one of the common GSM networks.
The ZDUE-GPRS-PLUS-VI supports the following GSM services
… CSD – Circuit Switched Data (Dial-up data connection)

The ZDUE-GPRS-PLUS-VI has the following interfaces for the connection of
meters: CL1, RS232 and RS485. The maximum permissible number of
meters can be connected to each of these interfaces simultaneously.
In addition, the device also has an auxiliary power source (9V) to supply the
meters.
For remote reading of the meters by the control centre, the ZDUE-GPRSPLUS-VI can connect all of the connected meters to the control centre in
sequence during a single connection. The control centre communicates
therefore with the connected meters directly. The ZDUE-GPRS-PLUS-VI just
transfers the data in both directions without modification. It only adapts
bitrate or data format, if the mode C function is enabled.
The integrated modem of the ZDUE-GPRS-PLUS-VI receives from the GSM
network data calls that have been initiated by the control centre.
The control centre can call
from the GSM network via a GSM modem (up to 9600 bps)
from the fixed network via an analogue modem (up to V.32; 9600 bps)
from the fixed network via an ISDN end device (V.110).
The ZDUE-GPRS-PLUS-VI that is called responds to the telegrams
transmitted by the control centre as follows:
It connects to the meters which are connected to its interfaces (CL1,
RS-232, RS-485).
It receives parameterisation commands and carries them out.

For protection against unauthorised access, password entry can be
configured. In this case the ZDUE-GPRS-PLUS-VI queries the caller for the
agreed password; the caller must then transmit it during the configured time
period (password timeout). If the password is incorrect or the timeout is
exceeded, the ZDUE-GPRS-PLUS-VI terminates the connection. The
password is parameterisable.

Functions
Although the ZDUE-GPRS-PLUS-VI does not have a real-time clock, a timer
is operated on the basis of and with the accuracy of the processor crystal.
This timer controls the automatic module reset function that can be activated
and configured in parameter class 79.
The automatic reset cycle starts when the device is switched on, i.e. the first
module reset takes place after the parameterised period elapses after the
device is started. Additional module resets then follow at the time intervals
determined by the parameterised period.
The time for the daily watchdog (which is likewise configured in parameter
class 79) is not used by the ZDUE-GPRS-PLUS-VI.
Configuration by
software
Configuration is performed using configuration software, e.g. Dr. Neuhaus
ZDUEset. Parameterisation commands are transmitted to the ZDUE-GPRSPLUS-VI with the aid of this software.
The parameterisation commands can be transmitted to the ZDUE-GPRSPLUS-VI via the GSM network (remote configuration) or directly via the RS232 interface (local configuration).
Configuration by DIP
switch
Using the DIP switch inside the ZDUE-GPRS-PLUS-VI the operation mode
of the ZDUE-GPRS-PLUS-VI can be switched between Meter-Mode and ATMode. Refer to chapter 5.1 and 5.2.
Firmware update
A firmware update can be performed via the configuration software (e.g. Dr.
Neuhaus ZDUEset) from a computer that is connected locally directly to the
RS-232 interface of the ZDUE-GPRS-PLUS-VI.

PIN
By factory default setting, the ZDUE-GPRS-PLUS-VI accepts SIM cards with
the PIN 0000
If your SIM card has a different PIN, you can change the setting of the
ZDUE-GPRS-PLUS-VI to the PIN of your SIM card in parameter class 79
(see chapter 3.6).
Alternatively, you can change the PIN using a mobile telephone.
With some network operators it is also possible to switch off the PIN query of
the SIM card. In this case it does not matter what the PIN is, because it is
ignored.
To insert the SIM card, proceed as follows:
1.
If the ZDUE-GPRS-PLUS-VI is connected to the power
supply, disconnect all poles.
2.
Loosen the screw on the terminal cover and remove the
terminal cover.
3.
Then remove the device cover.
4.
Open the SIM card holder and slide the SIM card into
the flap of the holder. When the SIM card holder is
closed, the gold-plated contacts of the SIM card must
be in contact with the gold-plated contacts of the holder.

The device conforms to protection class 2. The power supply to the
interfaces is electrically isolated from the electronics.
The antenna is connected to the type SMA
antenna jack. The position of the antenna
connection may vary depending on the device
type.
The antenna must be installed in such a way that
adequate signal quality is achieved. Make sure
that there are no large metal objects in close to
the antenna (e.g. reinforced concrete), as they
may have an adverse effect on the signal quality.
If an exterior antenna is mounted out of doors,
its support bracket must be earthed for
protection against lightning. Have this work
done by qualified personnel!
Observe the instructions included with your
antenna.
Antenna
characteristics
The antenna that is used should have an impedance of about 50 ohms. The
antenna must be adapted to the frequency bands of the GSM network
operator you have chosen: 850 MHz, 900 MHz, 1800 MHz or 1900 MHz.
In Europa and China GSM 900MHz snd DCS 1800MHz are used, in USA
GSM 850 MHz and PCS 1900 MHz are used. Please ask your network
operator.
The match (VSWR) of the antenna must be 1:2.5 or better.
Use only antennas from the accessories for the ZDUE-GPRS-PLUS-VI.
Other antennas could interfere with product characteristics or even lead to
defects.

3.5 Configuring the device if necessary
Basic settings as
shipped
The ZDUE-GPRS-PLUS-VI is shipped with a predefined factory setting.
Depending on requirements, it may need to be reconfigured. This can be
done :
remotely via a CSD connection
locally via the RS-232 interface (if no active CSD connection is
present).
Configuration
options
Among other things, the password protection, interface speeds, data formats
and the PIN that is to used can be parameterised.
For detailed information on parameterisation, see the chapter 6.
Parameterisation
options
The PIN can be set
remotely via a CSD connection
locally via the RS-232 interface (if no active CSD connection is
present).
For detailed information on parameterisation, see the chapter , see the
chapter 6.
SIM cards that have
no PIN
With SIM cards that have no PIN, the PIN query is skipped; the GSM
module does not wait for the PIN to be entered, but rather tries to check into
the GSM network directly.
Response to a
correct SIM PIN
If the PIN function of the SIM card being used is activated, and the PIN on
the SIM card being used agrees with the parameterised PIN, then the device
automatically tries to check into the GSM network.
Response to an
incorrect SIM PIN
If the PIN verification fails, it is repeated one time. If the repeated PIN
verification also fails, the device is blocked for further attempts (PIN ERROR
status), meaning that operation is no longer possible even with a SIM card
with the correct number. The Status/Error LED indicates a SIM/PIN error
(see 2)
This status is retained after the power supply is disconnected and
reconnected. This prevents the SIM card from being blocked if a third failed
attempt is made, after which it could only be unblocked using the PUK
(Personal Unblocking Key).
Unblocking the
device
To unblock the ZDUE-GPRS-PLUS-VI, a SIM card with a deactivated PIN
function must be inserted in the device. After starting, the device attempts to
check into the GSM network, and the PIN ERROR status is also reset.
Alternatively, the ERROR status can be reset using the service command for
setting a new PIN (see 6.5.7). This simultaneously sets the PIN
parameterised in the device.
3.6 Parameterising the SIM PIN

Interfaces
Characteristics
Communication with the GSM network takes place via an integrated GSM
module. Data transmission is according to the following standards:
GSM Rec. 7.02 asynchronous, RLP acc. to GSM Rec. 4.22,
Analogue modem type V.32 or ISDN type V.110
The meter interfaces of the ZDUE-GPRS-PLUS-VI are all parameterised
jointly, i.e. so that all of the interface parameter settings apply equally for all
meter interfaces.
The following values are supported by the meter interfaces:
The speed of the meter interfaces should not exceed the
speed of the GSM connection (9600 bit/s), because
otherwise data loss may occur.
Meters can be connected to and operated on all of the interfaces at the
same time, but only up to the specified maximum numbers.
In communication with the connected meters, all of the interfaces are
addressed simultaneously, i.e. no application (e.g. control centre) can
address any interface selectively. This means that unique addressing of the
meters is essential in order to prevent the transfer of data by several meters
at the same time.

Procedure for communication between control centre and meter
Fixed baud rate:
The speed is set to a fixed value via a parameter setting. The respective
meters that are communicating and the control centre connected via
modem exchange the data at the selected speed, i.e. the ZDUE-GPRSPLUS-VI works transparently. The speed does not exceed the GSM speed
(9600 bit/s), or may be less.
Variable baud rate:
Corresponds to the baud rate changeover as per Mode C according to DIN
EN 62056-21.
The starting speed is 300 baud. The speed is increased if the
communicating meter requests it from the corresponding interface, and the
interface confirms the requested baud rate. If there is no confirmation, the
communication continues at the current speed.
CL1 (Optional)
Interface CL1 conforms to the current loop interface according to DIN EN
62056-21.
This is an active 20mA interface with a 2-wire connection via the terminals
RTX- and RTX+ (terminals 6 and 7) of the terminal block.

Maximum that can be connected: 4 meters
Attention
If the CL interface is not used, it must be short-circuited with a wire jumper,
since otherwise the other interfaces of the ZDUE-GPRS-PLUS-VI will not
function.
The interface is isolated from the modem by means of an optocoupler.
When reading a meter, all of the characters transmitted to the meter are
transmitted back as an echo via the CL1 interface. These characters are
normally transmitted to the higher-level system. The echo is suppressed by
the modem.

5.1 AT Mode
Page 24 of 63 ZDUE-GPRS-PLUS-VI
Page 25
5.2 Meter Mode
To enter the meter mode disconnect the device from mains and set the DIP
switch 2.3) to „OFF“. Connect the device to mains again.
In the meter mode the ZDUE-GPRS-PLUS-VI accepts automatically
incoming calls from the central station and connects transparently the
connected meters with the central station. The start bitrate at the meter
interfaces is set by parameters to a fix value. The meter which
communicates and the central station exchange directly the data, i.e. the
ZDUE-GPRS-PLUS-VI just passes through the data between central station
and meter.
If EN 62056-21 mode C is activated, the ZDUE-GPRS-PLUS-VI adapts the
bitrate, but does not modify the data content.
The ZDUE-GPRS-PLUS-VI can be configured remotely via the GSM
connection using configuration commands in accordance to DIN EN 62056-
21.
Control
characteristics
The ZDUE-GPRS-PLUS-VI controls the communication between the control
centre and the meters that are connected to the ZDUE-GPRS-PLUS-VI in
accordance with protocol EN 62056-21 (Annex A):
in A/C mode,
in data readout and programming mode
including data saving (receiving) and acknowledgement.
The starting baud rate and the data format can be set for the following
interfaces: CL1 (Current Loop interface), RS-232, RS-485
Please note that these meter interface settings apply equally for all
interfaces.
In mode C-Operation the baud rate is changed over according to the
baud rate ID contained in the acknowledge telegram of the control
centre.
Detecting the end of
a communication
cycle
When reading data, the end of a communication cycle is detected when
>= 3 seconds no meter data is received (Mode A/C timeout)
the sequence ‘CR LF ETX‘ is detected (Mode C regular end)
In programming mode, the end of a communication cycle is detected when
a ‘Break‘ telegram is detected (Mode A/C break).
When a communication cycle is completed, the connection is terminated and
the baud rate of the serial interface driver of the meter interfaces is reset to
the parameterised start value.

Operation
Regular connection
termination
Termination of connection after transfer timeout:
The ZDUE-GPRS-PLUS-VI terminates a regular data connection after the
end of the transfer timeout. What this means is: For an existing connection,
if no data transfer takes place between the control centre and the ZDUEGPRS-PLUS-VI or the meters connected to the ZDUE-GPRS-PLUS-VI
within the specified timeout (default: 99 seconds), then the ZDUE-GPRSPLUS-VI terminates the connection.
Termination of connection by the control centre:
The control centre can itself terminate a connection at any time.

Configuration is performed with the software that is used for operation of the
control centre or a configuration software (e.g. Dr. Neuhaus ZDUEset).
Parameterisation commands are transmitted to the ZDUE-GPRS-PLUS-VI
with the aid of this software.
The software commands are described starting on page 33.
The parameterisation commands can be transmitted to the ZDUE-GPRS-
PLUS-VI via the GSM network (remote configuration) or directly via the RS232 interface (local configuration).
Remote
configuration via
the GSM network
Remote configuration is performed by the control centre, which transmits
parameterisation commands to the ZDUE-GPRS-PLUS-VI via the GSM
network. Transmission takes place according to DIN EN 62056-21 with BCC
secured protocol.
The parameterisation commands must be transmitted explicitly to the
address of the
ZDUE-GPRS-PLUS-VI.
The following device address is preset at the factory: 99999999
The device address is configurable. It can contain up to 16 characters;
numbers and letters are permitted.
Local configuration
The device can also be configured with the aid of a computer that is
connected via its COM port directly to the RS-232 interface of the ZDUEGPRS-PLUS-VI.
Precondition:
No GSM connection exists between ZDUE-GPRS-PLUS-VI and control
centre.
GSM offline status: Settings of the RS-232 interface
As soon as no GSM connection exists, the RS-232 interface is set by default
to the following setting:
19200 baud
8 data bits, No Parity, 1 stop bit
6.1 Configuration by software
Configuration
ZDUE-GPRS-PLUS-VI Page 27 of 63
Page 28
Configuration
Make sure that on the configuration computer that is connected the settings
of the COM port being used agree with this, and switch off all flow controls
(hardware (RTS/CTS), XON-XOFF).
If the computer connected to the RS-232 interface transmits prompting
telegrams with the device address of the ZDUE-GPRS-PLUS-VI (default:
99999999), the ZDUE-GPRS-PLUS-VI responds exactly as if it received the
prompting telegram from the remote control centre via the GSM network.
During local configuration via the RS-232 interface the ZDUE-GPRS-PLUSVI does not accept any calls from the GSM network.
GSM online status: Settings of the RS-232 interface
As soon as a GSM connection is established, the RS-232 interface switches
to the bitrate and data format being configured for the meter mode
Factory default is::
300 bit/s, 7E1, Mode C
The settings of the RS-232 interface for the GSM online status are
configurable
Attention
Please note that the RS-232 interface is only used if something is connected
to the current loop (it has at least one meter connected or a wire jumper
between the two current loop terminals RTX- and RTX+). In this case the
current loop LED must light up (see 2.1).
The following table provides an overview of the basic parameter classes
contained in the ZDUE-GPRS-PLUS-VI. These classes are assigned to
numbers, which must also be specified in parameterisation commands.

(R=Read/W=Write)
Summer/Winter time

reasons only, see 6.3.1)

Operating parameters
79
R/W
Parameters can only be written by writing a complete class(i.e. an offset
and length must also be specified with ‘0000‘ in a parameterisation
command).
When a class is expanded the new parameters must be appended in order
to ensure downward compatibility.
6.2 Parameters
Page 28 of 63 ZDUE-GPRS-PLUS-VI
Page 29
Each parameter class includes a range that is reserved for possible
expansions. Parameter expansions that are covered by these reserved
ranges do not lead to any incompatibility between different firmware
versions. If the expansion space is not sufficient, a new parameter class
must be created. This likewise does not lead to any incompatibility, because
a command to set/read this new parameter class from an older firmware will
be acknowledged with ERROR. The reserved parameter ranges are filled in
with ‘0‘ (0x30) during communication.
6.3 Parameter classes
In the following the parameters are sorted by classes and shown in the
same way as their notation in parameterisation commands. The respective
factory configuration is highlighted in bold. The specifications Offset, Len
and Values (ASCII) have the following meanings
Offset
Contains the relative address of a parameter within the
parameter class, relative to the class structure.
Len
Reflects the number of ASCII characters that are
necessary to depict the parameter during communication.
For strings only the number of ASCII characters defined
with ‘String Length‘ is significant (decimal-coded); any
string range that is not used must be filled in.
Values (ASCII)
Contains permissible values (ranges) for the individual
parameters during reading (W1 command) and reading by
means of an R3 command.
This class is implemented only for compatibility reasons. In other models it
specifies the changeover times of the clock from summer time to standard
time and from standard time to summer time. However, because the ZDUEGPRS-PLUS-VI does not have a real-time clock, the parameter class 54 has
no significance for operation of the ZDUE-GPRS-PLUS-VI. The parameters
of this class are read-only.
This class describes the general operating parameters of the ZDUE-GPRSPLUS-VI. It is defined as an open class, i.e. data sets that are longer than
what is defined here are accepted. The non-specified values are ignored in
evaluation by the device. When the parameters are read only the specified
values are output.

In the reception path the ZDUE-GPRS-PLUS-VI evaluates all characters in the data format 7N. This
applies to Mode C monitoring and the addressing and communication with the ZDUE-GPRS-PLUS-VI
(address "99999999"). The set data format is used in the transmission path to the control centre
(regardless of the application interface). A consequence of this function is that it does not matter for
the parameterisation of the ZDUE-GPRS-PLUS-VI which data format is set at the control centre or in
the modem.
As long as the device has the status "PIN without errors", the PIN is changed accordingly both in the
device and on the SIM. The change is performed in service operation immediately after the transfer
command for parameters. In CSD operation the PIN is saved on the SIM and in the device
immediately after it is applied. The new PIN is saved in the device parameters only after the PIN has
been successfully changed on the SIM.

6.4 Register data set of the ZDUE-GPRS-PLUS-VI
6.4.1 General
This register is only relevant for GPRS operation in the ZDUE-GPRS-PLUS-VI (see Section 7.4.4). If
the ZDUE-GPRS-PLUS-VIis not operated in GPRS mode, it does not contain any value (empty
brackets). If the ZDUE-GPRS-PLUS-VI is operated in GPRS mode, but it has not received any IP
address from the provider, then the register is given the value "000.000.000.000".

6.4.2 Format of the error status
The value is the hexadecimal representation of a 32-bit number that is
composed of the following status bits (in brackets is the bit no. in the
operation status word, see the section Status commands):
Bit 0 (Bit 08): Power return
Bit 1 (Bit 09): reserved "0"
Bit 2 (Bit 10): Parameter reloaded
Bit 8 (Bit 04): Parameter checksum error
Bit 16 (Bit 05): Parameter read/write error

The following sections document the commands supported by the ZDUEGPRS-PLUS-VI. The data set elements it contains are described in the
following.
The command descriptions use symbolic data set elements (e.g. for time
stamps). Their structure is the same for all command categories.

For the execution of various commands, the transfer of a set password (as a
2nd data set) is necessary. Depending on the parameterisation, the
following cases can arise in communication between ZDUE-GPRS-PLUS-VI
and control centre:
No set password parameterised in the ZDUE-GPRS-PLUS-VI (string
length = 0):
In this case the ZDUE-GPRS-PLUS-VI will not perform any evaluation
of the transmitted set passwords (all password-protected commands
can be executed!).
In this case, the request to transmit the password (P0 operand) when
programming mode is activated may be answered with the password
command (P1 command, password as desired). The control centre
can, however, alternatively also continue the communication with the
transfer of a different permissible VDEW command.

Page 35
Set password parameterised in the ZDUE-GPRS-PLUS-VI (default:
‘00000000‘)
All of the passwords transmitted by the control centre must be the
same as the ones that were parameterised, otherwise the
communication will be terminated by the ZDUE-GPRS-PLUS-VI by
means of a break command. The request to transmit the password
(P0 operand) when programming mode is activated must be
answered with the password command (P1 command). The direct
transmission of a different VDEW command is not permitted.
The setting and reading of the parameters is performed via W1/R3
commands (ASCII-coded characters).
The class is used to select the individual parameter segments; the
command parameters ‘offset‘ and ‘length‘ can in general be used to
access individual parameter or parameter ranges. This is, however, not
supported by the ZDUE-GPRS-PLUS-VI; the classes can only be read or
written completely (‘offset‘ and ‘length‘ of the class equal to ‘0000‘).

(The other parameters correspondingly)
After this command is carried out, the data are initially stored in the volatile
memory of the ZDUE-GPRS-PLUS-VI. In order to transfer them to nonvolatile memory, the parameter transfer command W1P01() (see Section
In order for newly written parameters to be transferred at a specific point in
time, the following command is defined.
Executing this command causes the data of the previously transmitted
command "Write class" to be transferred to the non-volatile memory. The old
parameters remain active before this command is executed.
If the data are read before transfer by means of this command, the old
values will be output!
The transmission of a break deletes the data set temporarily in the device
via class write commands. This way faulty "Write class" commands can be
undone, so long as the W1 command defined here has not been
transmitted. Moreover, the temporary data are discarded by a disconnect or
the occurrence of an inactivity timeout.

6.5.5 Time/date commands
The time and date commands have no function in the ZDUE-GPRS-PLUSVI. They are implemented for reasons of compatibility with other devices
and control centre programs.
The reading of the time and/or date from the ZDUE-GPRS-PLUS-VI makes
available the values that were written to the device previously with the
commands Set time and/or Set date. These data are saved in the device
only in volatile memory, and thus are no longer available after the power
supply is disconnected.
If no time is set, "0000000" is returned as the time; if no date is set,
"0070101".

In GPRS mode it is possible, as an alternative to communication via CSD, to
establish a data connection via the GPRS network to the ZDUE-GPRSPLUS-VI and the meters connected to it.
In this case the ZDUE-GPRS-PLUS-VI functions as an IP server to which an
IP connection must be established from a client (e.g. a control centre).
Attention
In order to be able to operate the ZDUE-GPRS-PLUS-VI in GPRS mode, a
SIM card enabled for GPRS must be used. Please consult your GSM
provider if necessary.
Configuration
options
In addition to the configuration options of the ZDUE-GPRS-PLUS-VI in CSD
mode, the ZDUE-GPRS-PLUS-VI in GPRS mode can be parameterised via
an IP connection opened by a client.
Remote
configuration via the
GSM network
As in the ZDUE-GPRS-PLUS-VI, see Remote configuration via
the GSM network, p. 27).
Local configuration
As in the ZDUE-GPRS-PLUS-VI , see Local configuration, p. 27.
Remote
configuration via
GPRS (fixed IP
service)
Configuration is performed using parameterisation software (control centre,
configuration tool (e.g. Dr. Neuhaus ZDUEset, etc.). This transmits the
parameterisation commands to the ZDUE-GPRS-PLUS-VI via the GPRS
network. Transmission likewise takes place according to DIN EN 62056-21
with BCC secured protocol.
The parameterisation commands must be transmitted explicitly to the
address of the ZDUE-GPRS-PLUS-VI. The following device address is
preset at the factory: 99999999
The device address is configurable. It contains 16 characters; numbers and
letters are permitted.

GPRS Modes
Provided that the parameterisation is correct, normally the device dials into
the GPRS network automatically and then sets up the IP server, so long as
GPRS mode is activated in class 82.
For example, faults in the GSM network or at the GPRS provider can cause
the log-in and dial-in attempts of the ZDUE-GPRS-PLUS-VI to fail. To
prevent the device from trying to establish a connection to the GPRS
network continuously (and in some cases incurring costs in the process), the
ZDUE-GPRS-PLUS-VI possesses two timers and a counter that can be
used to control its behaviour in the event of such faults. These parameters
are contained in parameter class 82 (see 7.4.3):
Counter: Number of dialling attempts to GPRS service before module
reset
Timer 1: Connection timeout for a failed GPRS login attempt
Timer 2: Waiting time after x failed GPRS login attempts
Here the ZDUE-GPRS-PLUS-VI proceeds in two steps. If a GPRS login
attempt fails, the number of login attempts defined in Counter are repeated
at certain intervals (Timer 1), until Timer 2 elapses, after which the device
carries out a module reset and the login process starts again from the
beginning.

The provider-specific GPRS access parameters for two different network
operators can be saved in parameter classes 60 and 61. Based on the IMSI
of the inserted SIM card, the firmware automatically detects the GSM Net ID
(first 5 digits of the IMSI) of the relevant provider and searches for this GSM
Net ID in parameter classes 60 and 61. When they are found, the
parameters contained in the corresponding class are used.
In the factory configuration these two classes are assigned with the GPRS
access parameters from T-Mobile (class 60) and Vodafone (class 61).
Length of the class 6* data sets: 327 bytes each
Factory configuration:
The factory configuration of class 60 (C60) and class 61 (C61) is shown in
bold.
Both parameter classes include a range that is reserved for possible
expansions. Parameter expansions that are covered by these reserved
ranges do not lead to any incompatibility between different firmware
versions. If the expansion space is not sufficient, a new parameter class
must be created. This likewise does not lead to any incompatibility, because
a command to set/read this new parameter class from an older firmware will
be acknowledged with ERROR. The reserved parameter ranges are filled in
with ‘0‘ (0x30) during communication.

Attention
A precondition for use of the GPRS/IP server functionality of the ZDUEGPRS-PLUS-VI is that the GPRS mode is activated in class 82.
The GPRS mode is deactivated by default!
GPRS data communication
The ZDUE-GPRS-PLUS-VI can be operated as an IP server. In this GPRS
mode a client (e.g. a control centre) establishes a bidirectional data
connection via the GPRS (General Packet Radio Service) of a GSM network
(Global System for Mobile Communication).
TCP/IP data communication for
machines that are
not TCP/IP-capable
themselves.
The communication via TCP/IP protocol that is necessary for this is provided
by the ZDUE-GPRS-PLUS-VI. It transmits data from electricity meters as well
as meters for other media which can be connected to the ZDUE-GPRSPLUS-VI’s interfaces and that are not TCP/IP capable themselves.
The ZDUE-GPRS-PLUS-VI in GPRS mode functions largely in the same way
as the CSD mode described above. Special features are described in the
following sections.

Control centre
Meter data and configuration via TCP/IP

Attention
In order to establish in GPRS mode an IP connection to the ZDUE-GPRSPLUS-VI from a client, the IP address of the ZDUE-GPRS-PLUS-VI must be
known to the client. For this reason it is advisable to use a SIM card with an
assigned fixed IP address.

GPRS Modes
Dialling into the
GPRS network
The connection to the GPRS provider is established automatically after the
device is restarted, so long as the GPRS mode is activated in class 82.
To successfully establish the connection, the GPRS access data must be
configured in the parameter classes 60 and 61:
Provider (selection of the GPRS network operator, e.g. T-D1,
Vodafone)
PDP_Context (access parameters of the GPRS network operator)
USER (login name in the GPRS network)
PASSWORD (login password in the GPRS network)
Dial-in string (not used)
DNS1 (primary Domain Name Server in the GPRS network; optional)
DNS2 (secondary Domain Name Server in the GPRS network;
optional)
In addition, the timing behaviour in the event of problems with the GPRS
dial-in can be set via class 82.
Attention
Please note that data packets are exchanged even when a connection is
(re-) established, when an attempt to connect to a remote station is made
(e.g. server is switched off, wrong destination address, etc.), and to maintain
a connection. Please especially note this when using networks which are
subject to charges!
Setting up the IP
server
Like dialling-in to the GPRS network, the IP server is set up automatically
when GPRS mode is activated. The following characteristics of the IP server
must be defined in class 82:
GPRS function (must be set in order for the device to work in GPRS
mode)
Server port 1 (port at which the server waits for incoming IP
connection requests; server port 2 is not considered)
Optionally the access authorisation can be limited in class 82:
Check source IP address of the client (the source IP address of a
connection request is evaluated)
Source IP addresses 1 to 5 (valid source addresses of a connection
request)
Check source port of the client (the source port of a connection
request is evaluated)
Source ports 1 to 5 (valid source ports of a connection request)
GSM data
communication
As a substitute (e.g. in case of failure of the GPRS connection) the ZDUEGPRS-PLUS-VI in GPRS mode can accept also CSD calls
(CircuitSwitchedData calls) from a remote station, thus providing
communication via the GSM network.
In this case the behaviour for data transmission to any other desired modem
in the GSM or fixed network is the same as described above.
Page 48 of 63 ZDUE-GPRS-PLUS-VI
Page 49
GPRS Modes
Changeover
between GPRS and
GSM operation
Manual changeover between GPRS operation and GSM operation is not
necessary. GSM data calls (CSD) are accepted if
GPRS mode is deactivated, but the device is checked into the GSM
network
the device is logged into the GPRS network
the IP server is set up, but there is no active IP connection
CSD calls are rejected if
a CSD connection already exists
an active IP connection has been established (independent of the
data flow)
In order to accept the GSM data call the GPRS connection is terminated.
When the GSM data call is complete, the GSM data call is restarted, the
GPRS connection is re-established and the IP server is set up again
Remote
configuration via
GSM data
connection
Remote configuration of the ZDUE-GPRS-PLUS-VI in GPRS mode is
possible via GPRS as well as via GSM connection.
Attention
For time-critical applications there can be limitations for GPRS
transmissions.
Although the transmission in the GPRS network generally only lasts a few
100s of milliseconds, due to the packet-switched infrastructure of the GPRS
network individual data packets may take quite a bit longer to arrive, i.e. up
to several seconds.
This can also lead to problems when time-critical control centre software is
used if it expects replies within a certain time after commands are sent out.
The ZDUE-GPRS-PLUS-VI in GPRS mode accepts exactly one active IP
connection at a time. If there is already an active IP connection to the ZDUEGPRS-PLUS-VI, further connection requests are rejected by the device.
Furthermore, the ZDUE-GPRS-PLUS-VI offers the possibility of regulating
the group of authorised clients. Two different mechanisms can be activated
independently of each other for this purpose:
7.4.1 Access protection
ZDUE-GPRS-PLUS-VI Page 49 of 63
Page 50
GPRS Modes
Source IP check
In parameter class 82, up to five IP addresses can be stored for the source
IP check. Only IP connection requests that have one of these IP addresses
as the source address will be accepted. If no match is determined for the
address, the ZDUE-GPRS-PLUS-VI rejects the connection request.
Precondition: The source IP check in parameter class 82 must be activated;
by default no IP check is performed.
Source port check
In parameter class 82, up to five port numbers can be stored for the source
port check. Only IP connection requests that have one of these port
numbers as the as the source port number will be accepted. If no match is
determined for the port, the ZDUE-GPRS-PLUS-VI rejects the connection
request.
Precondition: The source port check in parameter class 82 must be
activated; by default no port check is performed.
In the GPRS mode, the function indicators behave the same as in the CSD
mode; A existingTCP/IP connection is not indicated.

Attention
To use the GPRS-/IP-Telemetry funktion of ZDUE-GPRS-PLUS-VI it is
required, that the GPRS mode in parameter class 70 is activated. This
setting takes priority over the GPRS-/IP server mode (parameter class 82)
By default the GPRS-IP-Telemetry mode is NOT activated.
In GPRS-IP-Telemetry mode, as soon as a connection to internet or intranet
via GPRS is available, the ZDUE-GPRS-PLUS-VI establishes an IP
telemetry connection in accordance to E DIN 43863-4 to a selected IP-T
master. Therefore a corresponding account must be configured at the IP-T
master (e.g. Dr. Neuhaus TAINY SwitchingCenter V3). The login is made by
using login name and password.

The control station is also connected to the IP-Telemetry master. All the
communication between control station and ZDUE-GPRS-PLUS-VI is
transferred via the IP-Telemetry master.
The ZDUE-GPRS-PLUS-VI provides the opportunity to define a secondary
IP-Telemetry master. If the connection to an IP-Telemetry master cannot be
established (e.g. master not reachable) or is refused by the master (e.g.
invalid user name/password combination), the other master can be used as
an alternative by the ZDUE-GPRS-PLUS-VI.
The primary and secondary IP-Telemetry master may also reject a login
attempt for load balancing reasons, provided this service is activated within
the respective TAINY SwitchingCenter. In this case the rejecting IPTelemetry master reroutes the ZDUE-GPRS-PLUS-VI by sending the IP
address of an alternative IP-Telemetry master to the device. This IP address
is independent from the server settings of the ZDUE-GPRS-PLUS-VI.
In the GPRS-IP-Telemetry mode, the function indicators behave the same
as in the CSD mode; An existing IP-Telemetry connection is not indicated.

As being described in Section 7.4.4.
The error status format is described in Section 6.4.2.
The ZDUE-GPRS-PLUS-VI in GPRS-IP-Telemetry mode supports the same
communication commands as in CSD mode. There are also GPRS-specific
commands; these are listed in the following.
The three parameter classes 70, 76 and 78 additionally contained in the
ZDUE-GPRS-PLUS-VI for GPRS-IP-Telemetry mode are configured
according to the parameterisation of the ZDUE-GPRS-PLUS-VI standard
classes (see 6.5.3) and saved to non-volatile memory in the device using the
parameter transfer command (see 6.5.4).
