General introduction
General introduction
In the past the integration of a fieldbus connection required an enormous effort from the progress
engineers. On account of the large variety of communication systems it is not enough to compile
the right combination of communication hardware; due to their standards and fundamentals different busses also require the corresponding skills of the engineers.
This does not apply in case of the UNIGATE® IC by Deutschmann Automation any more. All digital functions, software, stack and driver as well as optocoupler are integrated on a UNIGATE®
IC in correspondence with the standard. In addition to the reduction of the required size, also different fieldbusses can easily be integrated.
Through the flexible firmware of UNIGATE® IC no software-changes are required on the
side of the customer!
Since 1997 Deutschmann Automation has experience in the field of fieldbus gateways; this
enormous experience results in the UNIGATE® IC as a consistent sequel of this successful
product line.
Terminology
In the entire document and in all parts of the software that is to be used, the terms Input and Output are used. Input and Output are ambiguous, always depending on the viewpoint. We see the
fieldbus as central interface and as integral component of your device; therefore in all places it is
always referred to data from the viewpoint of the Slave, that is Input data, as data from the Master to the Slave - regardless of the used bus.
Representation of numbers
Numbers in decimal format are always represented without prefix and without suffix as well.
hexadecimal numbers are always marked with the prefix 0x.

Deutschmann Automation GmbH & Co. KG
The UNIGATE® IC
Technical introduction
The UNIGATE® IC by Deutschmann Automation contains all components that are required for
the communication in a fieldbus in one single module. Therefore a developer does not have to
take care for that detail any more, only a hardware redesign is necessary in order to integrate the
UNIGATE® IC and the required plug connectors.
2.2
Availability
The module is available as ProfibusDP. Further fieldbusses are either planned or being worked
on. They will only differ in the connections of the busses. The meaning of the general pins 1 - 9
as well as 24 and 26 - 32 will remain unchanged also for further fieldbus implementations.
You can find an up-to-date list for all UNIGATE ICs under:
http://www.deutschmann.de.
2.3
Firmware
UNIGATE® IC is programmed via scripts. On principle any script, that has been developed for a
UNIGATE® SC, can also be operated on the UNIGATE® IC.
2.4
The serial standard interface
Intelligent devices, that already feature a micro controller or a microprocessor, are generally supplied with a serial asynchronous interface with a TTL-level. It is directly connected with the TTLinterface of the UNIGATE® IC. For more information on this serial interface see chapter 4 on
page 18.
2.5
The synchronous interface
In addition to the standard interface there is also the possibility of the synchronous input and output. That way for instance digital IOs can be connected through shift register components or also
analog IOs can be connected through a DA-converter with serial in-/output. For synchronous IOs
256 signals at the most can be used (256 bit). Wiring examples can be found in chapter 3.5 on
page 13 and for software examples see chapter 5.2 on page 19. It is also possible to build, for
instance digital or analogous I/O-modules, with the customer’s device not being equipped with an
own controller. The fieldbus IC is also operable autonomously without that controller.
2.6
The Debug-interface
The UNIGATE® IC features a Debug-interface, which allows to process a script step by step and
also to monitor or manipulate data. This is indispensable for the development of a script. Usually
a script is developed with the software Protocol Developer. For more details take a look at the
instruction manual Protocol Developer.
All interfaces can independently be used at the same time.

Hardware design
This chapter gives basic advise, that is required in order to load UNIGATE® IC into your own
hardware designs. In the following all ports of UNIGATE® IC are described in detail.
3.1
Ports
UNIGATE® IC features 32 pins in its layout as a DIL 32 component. Pin 10 -12 and 21 - 23 as
well are not wired due to the electrical isolation. The exact mechanical dimensions can taken
from chapter 11 on page 31.
In the layout boreholes for ALL 32 pins have to be planned.

Here only the synchronous serial interface is used, the asynchronous serial interface is basically

For this operating mode no additional controller is required on your application!

The serial interface
4
4.1
Deutschmann Automation GmbH & Co. KG
The serial interface
Overview
The serial interface is an important connection between the UNIGATE® IC and the micro controller of your application. The interface is designed in a way so that your application at least does
not have to be changed on the software-side. The wide range of services of the UNIGATE® IC’s
serial interface constitutes the basis for it. The UNIGATE® IC allows to connect controllers with a
baudrate of 110 bit to 625 kbit. The baudrate for the communication itself is permanently stored
in the module. The maximum size for the IO-data kann be taken from the table in chapter 11.2.1,
line „RS-buffer size“.
Depending on the read-in script of the UNIGATE® IC, the module carries out actions independently, in order to identify data from the connected device. For customers who already have a
software-adaptation at he company Deutschmann Automation, this protocol as well or a Script
after an adaptation can be processed by the IC.
Anyway, the IC will take over the communication with the fieldbus independently.
4.2
Initialization of the serial interface
The initialization of the interface is carried out by script-commands, such as “Set baudrate“, “Set
databits“, “Set parity“. For a detailed description of these commands see the online documentation for the Protocol Developer or the instruction manual for the Protocol Developer.
4.3
Use of the serial interface
The serial interface can freely be programmed by the user. Efficient script-commands for sending
and receiving data are available; just to mention some possibilities: such as waiting with timeout
for a character, waiting for a fixed number of characters or also sending and receiving data in the
Modbus RTU. A reference to these commands is offered in the online documentation for the Protocol Developer as well as in the instruction manual for the Protocol Developer.
4.4
Further operation modes
In the modes configuration mode and firmware-update mode the serial interface also serves to
configure the standard software or to carry out a firmware-update. More details can be found in
chapter 10.5 on page 30.

Synchronous interface
Synchronous interface
5.1
Overview of the synchronous serial interface
The synchronous serial interface is an interface of the IC to clocked shift registers. About this it is
not only possible to input or output digital signals but also the addressing of DA- or AD-converters with clocked serial interface is possible as well as the connection of LEDs or reading in rotary
switches. Connection examples are stated in chapter 3.
The synchronous serial interface can also be used in products, that do not feature an own micro
controller, in order to realize digital IO-modules for instance. Up to 256 signals for input and output each can be processed. The UNIGATE® IC’s firmware is responsible for the different amount
of input and output signals and takes on control for it.
The data exchange with the script is made with the commands "Set ShiftRegisterInputType / Set
ShiftRegisterOutputType" and "Set ShiftRegisterInputBitLength / Set ShiftRegisterOutputBitLength" and “WriteShiftRegister“ as well as “ReadShiftRegister“.
In order to make the use of the synchronous serial interface as efficient as possible, it is possible
to set a „shift register“ and a „bit length“ via the script, whereas both can be changed dynamically
within the script by script commands.
As a result the firmware is in the position to control the entire data transfer with the hardware and
the data exchange can be carried out as quickly as possible.
At present the shift register types "RiseClk_RiseLoad" and "RiseClk_LowLoad" are implemented,
that are required when using for instance the 74595 and 74165 (see also chapter 5.2).
Other types can be complemented very fast and simple - by Deutschmann Automation GmbH.
The shift register type defines the edges or the levels on how data is output to the hardware or
how data is read in.
In this case the data exchange is restricted to the script commands "WriteShiftRegister" and
"ReadShiftRegister". The clock speed is min. 150kHz, so that for instance a shift register with 32
bit is read in or written in a time period of max. 215µs.
5.2
Script-example
var InBuffer: Buffer[2];
Var OutBuffer: Buffer[2];
MoveConst (OutBuffer[0], #0x58#0x21 ),
Set ( ShiftRegisterInputType , RiseClock_FallLoad ) ;
Set ( ShiftRegisterOutputType , RiseClock_RiseLoad ) ;
Set ( ShiftRegisterInputBitLength , 16 ) ;
Set ( ShiftRegisterOutputBitLength , 16 ) ;
WriteShiftRegister ( OutBuffer[0] ) :
ReadShiftRegister ( InBuffer[0] ) ;
// Input data is now in the InBuffer
// 0x58 is applied to the outputs of the analog converter
// 0x21 at the shift register’s outputs

The Debug-interface

Deutschmann Automation GmbH & Co. KG
The Debug-interface
Overview of the Debug-interface
The UNIGATE® IC features a Debug-interface, that allows a step-by-step processing of a script.
Normally this interface is only required for the development of a script.
6.2
Starting in the Debug-mode
When applying power to the UNIGATE® IC (power up) the firmware will output the binary
character 0 (0x00) after a self-test was carried out on this interface. If the IC receives an
acknowledgement via this interface within 500 ms, it is in the Debug-mode. The
acknowledgement is the ASCII-character O (0x4F).
With the start in the Debug-mode the further execution of script-commands will be put to a stop.
6.3
Communication parameter for the Debug-interface
The Debug-interface is always operating with 9600 baud, no parity, 8 data bit, 1 stop bit. It is not
possible to change this parameter in the Protocol Developer. Please consider the fact that these
settings have to be in accordance with those of the PC-COM-interface and that the flow control
(protocol) has to be set on „none“ there.
6.4
Possibilities with the Debug-interface
Usually the Protocol Developer is connected to the Debug-interface. With it a step-by-step processing of a script, monitoring jumps and decisions and looking at memory areas is possible.
Moreover breakpoints can be set. It basically possesses all characteristics a software-development tool is typically supposed to have. However, it is also possible to carry out a Scrip-update
via this interface.
6.5
Commands of the Debug-interface
The commands for the use of the Debug-interface are described in the instruction manual Protocol Developer.

Script and configuration
Script and configuration
7.1
Overview
In the configuration mode the scripts and configurations, stored in the UNIGATE® IC, can be
replaced or updated via the serial interface.
7.2
The configuration mode
If the pin „ConfigMode“ pulled to GND during the PowerUp or Reset, then the UNIGATE® IC
starts in the configuration mode. In this mode it is possible to communicate with the IC without
processing the regular software. In this mode it is possible to change the UNIGATE® IC’s settings of the standard software or to write a new script in the UNIGATE® IC. It shows its start in
the configuration mode by issuing a status message, which might look as follows:
IC-PB-SC V5.9A[25] (c)dA Script(2k)="Leer" Author="Deutschmann Automation GmbH" Version="1.0" Date=21.08.2001 SN=47110001 ID=1
The configuration of a UNIGATE® IC is restricted to setting the Profibus-address (see also chapter 9.2 ’Setting the Profibus-address’).
7.3
Update the script
• The preferred version is the one, where the IC is inserted into the basis board, available from
Deutschmann Automation and the Deutschmann tools (software WINGATE with “Write Script“
under “File“ or with the software Script Download Tool) are used.
• In your application the script can also be replaced automatically by your hostreplaced. In the
following flow chart the handshake is shown.

The operational sequence is as follows:
The Gateway has to be in the config-mode.
The script-download is initiated with "Ctrl-P (=0x10)".
After taht the data follows byte by byte as ASCII-hex-characters.
The download is terminated with a "LF (=0x0A)".
Afterwards the word-checksum follows as ASCII-hex-characters.
The Gateway responds with a clear text reply to that download and carries out a warm start.
Example:
The following 4-bytes script is supposed to be downloaded: 0x01 0x12 0x5A 0x23
The sum of teh bytes is 0x0090 as checksum.

Generating a script
8
8.1
Deutschmann Automation GmbH & Co. KG
Generating a script
What is a script?
A script is a sequence of commands, that are executed in that exact order. Because of the fact
that also mechanisms are given that control the program flow in the script it is also possible to
assemble more complex processes from these simple commands.
The script is memory-oriented. It means that all variables always refer to one memory area.
While developing a script you do not have to take care of the memory management though. The
Protocol Developer takes on this responsibility for you.
8.2
Memory efficiency of the programs
A script command can carry out e. g. a complex checksum like a CRC-16 calculation via data.
For the coding of this command only 9 byte are required as memory space (for the command
itself). This is only possible when these complex commands are contained in a library.
A further advantage of this library is, that the underlying functions have been in practical use for a
couple of years and therefore can be described as ’void of errors’. As these commands are also
present in the native code for the controller, at this point also the runtime performance of the
script is favorable.
8.3
What can you do with a script device?
Our script devices are in the position to process a lot of commands. In this case a command is
always a small firmly outlined task. All commands can be put into classes or groups. A group of
commands deals with the communication in general. This group’s commands enable the gateway to send and receive data on the serial side as well as on the bus-side.
8.4
Independence of buses
Basically the scripts do not depend on the bus, they are supposed to operate on. It means that a
script which was developed on a Profibus gateway can also be operated on an Interbus without
changes, since the functioning of these buses is very similar. In order to also process this script
on an Ethernet gateway, perhaps further adjustments have to be made in the script, so that the
script can be executed reasonably.
There are no fixed rules how which scripts have to operate properly. When writing a script you
should take into account on which target hardware the script is to be executed, so the necessary
settings for the respective buses can be made.
8.5
Further settings at the gateway
Most devices require no further adjustments, except for those made in the script itself. However,
there are also exceptions to it. These settings are made by means of the software WINGATE. If
you know our UNIGATE-series, you are already familiar with the proceeding with it. An example
is the adjustment of the IP-address and the net-mask of an Ethernet-gateway. These values
have to be known as fixed values and are not available for the runtime. Another reason for the
configuration of the values in WINGATE is the following: After an update of the script these values remain untouched, i. e. the settings that were made once are still available after a change of
the script.
Only this way it is also possible that the same script operates on different Ethernet-gateways,
that feature different IP-addresses.

8.6
Generating a script
The use of the Protocol Developer
The Protocol Developer is a tool for an easy generation of a script for our script gateways. Its
operation is exactly aimed at this use. After starting the program the script that was loaded the
last time is loaded again, provided that it is not the first start.
Typical for Windows script commands can be added by means of the mouse or the keyboard. As
far as defined and required for the corresponding command, the dialog to the corresponding
command is displayed, and after entering the values the right text is automatically added to the
script. The insertion of new commands by the Protocol Developer is carried out in a way that
existing commands will not be overwritten. Generally a new command is inserted in front of the
one where the cursor is positioned. Of course the commands can also be written by means of the
keyboard or already written commands can also be modified.
8.7
Accuracies of the baud rates at UNIGATE IC
The baud rate of the serial interface is derived from the processor’s crystal frequency.
Meanwhile all Script-gateways, except for the MPI-Gateways (20 MHz), are working with a crystal frequency of 40 MHz.
You can enter any desired integer baud rate into the script. After that the firmware adjusts the
baud rate, that can be derived the most precisely from the crystal frequency.
The baud rate the gateway is actually working with (BaudIst) can be determined as follows:
BaudIst = (F32 / K)
F32
= Crystal frequency [Hz] / 32
K
= Round (F32 / BaudSoll);
Round () is a commercial roundoff
Example:
The actual baud rate is to be calculated, when 9600 baud are pre-set, where the gateway is
operated with 40 MHz:
F32
= 40000000 / 32 = 1250000
K
= Round(1250000 / 9600) = Round(130.208) = 130
BaudIst = 1250000 / 130 = 9615.38
I. e.: The baud rate actually adjusted by the gateway is 9615.38 baud
The resulting error in per cent can be calculated as follows:
Error[%] = (abs(BaudIst - BaudSoll) / BaudSoll) * 100
In our example the following error results:
Error
= (abs(9615.38 - 9600) / 9600) * 100 = 0.16%
In practise errors below 2% can be tolerated!
In the following please find a listing of baud rates at a 40 MHz-crystal frequency with the corresponding errors:

Script processing times
The Script is translated by the Protocol Developer and the consequently generated code is
loaded into the Gateway. Now the processor in the Gateway interprets this code. In this case,
there are commands that can be processed very fast (e. g. "Set Parameter"). There are also
commands, however, that take longer (e. g. copying 1000 bytes). Consequently, for one thing the
processing time differs due to the kind of Sript command. But the processing time of the Script
commands is considerably more determined by the processor time that is available for this process. Since the processor has to carry out several tasks simultaneously (multitasking system)
only a part of the processor's capacity is available for the Script processing. The following tasks in the order of priority - are executed on the processor:
• Sending and receiving data at the Debug-interface (provided that the Protocol Developer has
been started on the PC)
• Sending and receiving data at the RS-interface
• Sending and receiving data at the Fieldbus-interface
• Tasks controlled via internal clock (1 ms) (e. g. flashing of an LED)
• Processing of the Script
From experience approximately 0.5 ms can be calculated for each Script line. This value confirmed itself again and again in many projects as a standard value. He is always quite right if the
processor has enough time available for the Script processing.
By means of the tasks mentioned above, the following recommendation can be formulated in
order to receive a rather fast Script processing:
• Deactivate the Debug-interface (it is the normal case in the serial use)
• Keep the data length at the RS-interface as small as possible. The baud rate is not the problem
here, but the amount of characters which are transfered per second.
• Do not unnecessarily extend the data length at the Fieldbus side. Especially at acyclical bus
data, if possible do only send them when changes were made. The data length at buses that
are configured to a fixed length (e. g. Profibus) should not be longer than absolutely necessary.
If the processing time should be too large in spite of these measures, there is the possibility to
generate a customized Script command, that executes several tasks in one Script command.
Please contact our support department for this purpose.

Description of the DPV1- / DPV2-functions
DPV1
Die DPV1-Erweiterung besteht aus folgenden Funktionen:
1. Acyclic data exchange with Class1-Master (e. g.: PLC)
This function is optional for a DPV1-Slave. Our gateways support this function as a default. By
means of this function the Class1-Master can read and write data from the slave acyclically. This
data is processed by the script in the gateway. The channel for the acyclic data exchange is set
up firmly during the parameterization.
2. Acyclic data exchange with Class2-Master (e. g.: control unit)
This option is optional for a DPV1-Slave as well. Our gateways support this function as a default.
By means of this function the Class2-Master can read and write data from the slave acyclically.
This data is processed by the script in the gateway. The channel for the acyclic data exchange is
set up prior to every data exchange and closed again afterwards.
3. Alarm handling
Aso the alarms are optional. If they are activated, they replace the device-specific diagnosis. At
present our gateway does not support alarms.
Every DPV1-Slave must support the extended parameterization since it is determined in Octet 8
of the parameterization telegram whether it is a DPV0- or a DPV1-Slave.
A DPV1-Slave can also be operated at a DPV0-Master if the DPV1-functions remain turned off.
9.1.2
DPV2
Die DPV2-enlargement consists of the following functions:
1. Isochron Mode (IsoM)
It means the clock-synchronous behavior of a bus system. This function is optional for a DPV2Slave and is activated via the GSD-file. At present our gateway does not support this mode.
2. Data Exchange Broadcast (DxB)
It means the communication between Slaves (inter-communication). This function is optional for
a DPV2-Slave and is activated via the GSD-file. At present our gateway only supports the function of the „Publisher“ (sending data to other Slaves). The function „Susbcriber“ (receiving data
from other Slaves) is not supported at present.
3. Up- And Downlaod
This function is also optional for a DPV2-Slave and at present it is not supported by our gateway.
4. Time-synchronization (Time stamp)
This function is also optional for a DPV2-Slave and at present it is not supported by our gateway.
5. Redundancy concept
This function is also optional for a DPV2-Slave and at present it is not supported by our gateway.

Deutschmann Automation GmbH & Co. KG
Setting the Profibus-address
There are different possibilities to set the IC’s Profibus-address.
1.
Setting the address through the configuration
The UNIGATE® IC has to be in the configuration mode (see also chapter 7.2 ’The configuration mode’). With WINGATE it is now possible to set the address. This address is preserved
until it will be changed again.
2.
Setting the address through the Script
The address can be stored in the Script as well. This proceeding, however, is likely to be of
interest for a few applications only, since it is necessary to change the Script in order to also
adjust the Profibus-address (see also the following Script example).
3.
Setting the address through the serial interface
The address can also be transmitted to the IC through the serial interface. Then the address
can be set with the Script command "SetByVar". This possibility should be used in case your
device has a control front available and the menu of the front can be extended by the setting
"Profibus-address". The adjustment of the Profibus-address through the serial interface is
the most convenient possibility for those applications.
4.
Setting the address through the bus itself
Address 126 is reserved for devices that do not feature the hardware which is required to set
the bus address (such devices with protection class IP 65). Address 126 has to be configured through WINGATE (see point 1.).
.
5.
28
Connecting the rotary switches to the shift registers
Rotary switches can be connected to a shift register as well as to our basis board. Now it is
possible for the Script to read those switches and to set them as fieldbus-address. Basically
the following Script can be used for it.

Firmware-update
Deutschmann Automation GmbH & Co. KG
10 Firmware-update
10.1
Overview
UNIGATE® IC has a 64 kbyte flash memory for the firmware. In the firmware-update-mode the
firmware can be replaced via the UNIGATE® IC’s serial interface.
10.2
10.2.1
Adjusting the firmware-update-mode
Adjustment by hardware
UNIGATE® IC can be brought to the firmware-update-mode by the hardware. For it the signal BE (boot enable) has to be pulled to the potential GND during the Power-up-process.
10.2.2
Adjustment by software
If the UNIGATE® IC is in the configuration mode (see chapter 7.2 on page 21) it can be brought
to the firmware-update-mode interactively through the command CTRL-F (0x06). After sending
the command a security query follows, that has to be answered with J or N (J = Yes, N = No).
After a positive confirmation the IC is re-started in the firmware-update-mode.
10.3
Execution of the firmware-update
The safest way for the firmware-update is the use of the basic board combined with the software
“FDT.EXE“ (firmware-download-tool). These tools are available from Deutschmann Automation
(see chapter 12 on page 33).
It is also possible to use the description and the tools of the manufacturer of the controller
(TEMIC, 89C51RD2) as well.
10.4
Note on safety
The firmware-update should only be carried out when there is no other possibility left. A firmware-update-process that has already been started CANNOT be undone. With it the previously
used firmware is permanently unusable.
10.5
Operation mode of the IC
Standard-operation mode
This mode is required for the regular use of the IC. In this mode the IC will process all script-commands and normally exchange the corresponding user data. The bus as well is operated in this
mode through the IC.
Configuration mode
In the configuration mode the UNIGATE® IC will carry out a self-test after the start (or after a
reset). After a successful self-test it will wait for further commands. Here it is possible to load a
translated script into the unit or to initialize the firmware-download-mode.

12 Accessory
The following tools are available from Deutschmann Automation.
12.1
Development board
The development board (also called basis board) is a circuit board on which the UNIGATE® IC
can be installed. The IC is installed in the ZIF-socket. The ZIF-socket allows an easy insertion
and remove of the IC.
Together with the IC this board is almost compatible to 100% with a script gateway of the SCseries. Depending on the version only the sizes of the I/O-buffers and the available memory are
smaller than at the regular UNIGATE-SC.
12.2
Adapter RS232
In an application the adapter RS232 offers the possibility to replace an existing driver MAX 232
(only in DIL-16-housing) by this adapter. This board allows the use of the IC according to chapter
3.4 on page 12. Please note that with it the Profibus does not offer a connection conforming to
the standards. With a plug adapter, however, at least the operation of Profibus is possible.
The hardware is only meant for development purposes. It offers the possibility to make an
existing application capable for bus connection in no time and to test the IC’s utilizability and
functionality.
12.3
Adapter RS485
From the functionality’s point of view the RS485 adapter is the same as the RS232 adapter. It
offers the possibility to replace a module LS 176 (only in DIL-8-housing) by the IC.
There are the same restrictions as for the RS232 adapter.
12.4
FirmwareDownloadTool (FDT)
The FirmwareDownloadTool is available for download from our homepage: it is required for an
update of the firmware. Condition for it is, that a PC can be connected to the serial of the IC. The
software describes the procedure of an update itself.
12.5
Protocol Developer
The Protocol Developer is the development environment for scripts, that also contain the Debugger. This software package also contains the documentation to all script-commands. This software is available for download from our homepage at http://www.deutschmann.de. The
instruction manual for the Protocol Developer, which is available in pdf-format, gives further
advise on how to use the software.
12.6
Starterkit IC
The Starterkit IC contains
• a UNIGATE® IC for the selected fieldbus
• a UNIGATE® IC-basis board to put on the UNIGATE® IC
• a plug-in power pack to supply the UNIGATE®
• a connection cable
• Software and documentation complete the packet. Additionally a 3-months hotline service is
included

Accessory
Deutschmann Automation GmbH & Co. KG
The basis board contains a socket to put on the IC, all RS- and fieldbus-sided connectors,
switches and LEDs. Actually you cannot tell the difference to a ’normal’ UNIGATE® any more.
With the basis board your UNIGATE® IC can be connected to your product within a few minutes,
in order to prepare the implementation then. Through the basis board you have direct access to
all functions of the IC. With the Protocol Developer you write your script quickly and with the IC in
the basis board it can be tested effectively. Master simulation of the fieldbus side is available as
add-on for the described Starterkit. Besides the corresponding fieldbus-master simulator the
required connection cable to the PC and a PC-software for the representation of the RS-data and
the fieldbus-data is also supplied.

13.3.7 Slide switch (RS485 termination)
If the gateway is operated as the first or last physical device in the RS485 bus, there must be a
bus termination at this gateway. In order to do this, either a bus terminating resistor in the connector or the resistor (150:) integrated in the gateway must be activated. In order to do this,
slide the slide switch to position ON. In all other cases, the slide switch must remain in position
OFF. Please refer to the general RS485 literature for further information on the subject of bus terminations.
If the integrated resistor is used, please allow for the fact that this also activates a pull-down
resistor (390 :) to ground and a pull-up resistor (390:) to VCC.
At the RS422-interface the transmission line is terminated. The receive line is always firmly
terminated.

Representation of the data in ProfibusDP
15 Representation of the data in ProfibusDP
Any standard-compliant ProfibusDP Master can exchange data with the gateway. It is also possible to use very "simple" Master connections owing to the data structure.
15.1
Configuration telegram
After programming, the Master must send a configuration telegram to the corresponding Slave.
The configuration telegram provides the Slave with information on the length of the input/output
data. If the user has set the ’Length byte’ flag, this means the maximum data lengths. Otherwise,
it means the actual lengths.
The user normally also configures the configuration telegram in the project planning tool where
he may also, if necessary, enter the address range in which the useful data is stored.
You can write up to 16 bytes or words in one octet of the DataUnit (DU). Inputs and outputs having the same format can be combined in one octet. Otherwise, you must use as many octets as
the number of different bytes/words you wish to use and which cannot be combined in one octet.
If the module detects, during the check, that the maximum permitted input/output data lengths
have been exceeded, it signals incorrect configuration to the Master during a subsequent diagnostic scan. It is then not ready for useful data communication.

the status messages are transfered there. Since the gateway’s error numbers have been transfered in the external diagnosis it became necessary then to carry out an adaptation at DPV1.
Now the 3 bytes "0x81, 0x00, 0x00" have been inserted in front of the actual error message in
order to be compatible with DPV1-masters. With it a DPV1-master identifies our gateway’s error
as status message now.
This results in a different representation of our gateway error in Profibus. At DPV0 the error number is transmitted in unmodified form as 1 byte external diagnosis. In case DPV1 has been activated in the gateway through the GSD-file, the error number occurs as 1 byte status message.
Supposing the DPV1 is activated and a master (which does not support the alarms and status
messages) is connected, then our gateway error number is presented as "external diagnosis"
with 4 bytes (see above), at which point the 4th byte contains the error number and the preceding
3 bytes (0x81, 0x00, 0x00) can be ignored.
15.4
Data exchange
After the Master, in the diagnostic, detects that the Slave is ready for data exchange, it sends
data exchange telegrams. Either the Master stores the data in the input/output direction in the
address area specified during project planning or the control program must fetch or retrieve the
data using specific function blocks.
