Micro Automation Set 19 ID-Nummer
Foreword
Micro Automation Sets are fully functional and tested automation
configurations based on A&D standard products for simple, fast and
inexpensive implementation of automation tasks for small-scale
automation. Each of these Micro Automatic Sets covers a frequently used
subtask of a typical customer problem in the low-end range.
The sets help the customer to obtain answers with regard to required
products and the question how they function when combined.
However, depending on the requirements of the system, a variety of other
components (e.g., other CPUs, power supplies, etc.) can be used to
implement the functionality on which this set is based. See respective
SIEMENS A&D catalogs for these components.
The Micro Automation Sets are also available at:

Application Areas and Usage
Micro Automation Set 19 ID-Nummer
1 Application Areas and Usage
Automation task
Cyclically updated process data and event controlled status information, is
to be transferred from geographically distributed plant segments to a
central station. For cost reasons, a wireless transfer medium is to be used.
Automation solution  Set 19
S7-200 stations are integrated into the distributed plant segments and send
the relevant data to a PC-based central station with internet connection via
GPRS mobile connection. A performat WinCC user interface offers a
structured display and archiving of the data.
Fields of application
The Micro Automation Set is particularly suitable for application of
geographically distributed automation systems.
Simple automation tasks are solved centrally and important process data
are sent to a PC-based central station via mobile communication (GPRS).
The set is particularly suited for the following branches.
" Water supply,
" Oil and gas industry
" District heating
" Traffic technology
" Open pit mining
" Power supply
Your benefit
" Central display of current process data of distributed plant sections
" Reducing wiring expenses due to wireless communication
" Cost-effective data transmission due to payment based on data volumes.
" High availability and performant communication due to standardized mobile
communication technology

Layout diagram for Remote Station
The remote station consists of an S7-CPU 224 XP. A GPRS mobile radio
modem (MC45T with antennae) is connected to the controller with a serial
PC/PPI cable. The energy supply of the individual component occurs via
the load current supply of the CPU.
Note
In order to keep it simple, only one remote station is displayed in this
Micro Automation Set.

4 Functionality
Function principle
Using the example of value 123 (e.g. 123 produced units) the principal
function method of the Micro Automation Sets is explained.
Daten
Table 8:
No. Function Note
1 Data, such as 123 produced units, is obtained from the The process values are
running process and transferred to the controller (e.g. simulated in the Micro
digital or analog inputs). Automation Set.
2 In the CPU, data (e.g. 123) are embedded in a UDP/IP
protocol.
3 The compiled protocol is transferred to the modem via the
user programmable interface of the CPU.
4 From the modem, the data is sent to the GPRS network
of the mobile service provider.
5 Connecting the GPRS network of the mobile service
provider with the internet enables sending process data
(e.g. 123) to the internet.
6 The internet routes the data (e.g. number of produced
data, 123) to the internet service provider of the central
station.
7 The internet service provider directs the data to the target
address.

8 The standard Windows PC receives the data.
PM Open recognizes the user protocol and transfers the
identified process values to an internal variable (e.g. Tag
Name Units=123).
The data transfer occurs via the internet. Restricted availability may
!
lead to loss of data.
Warning
The used UDP protocol does not enable monitoring the data
transfer. (e.g. wire break in the PC network)

Software Examples for Startup
Micro Automation Set 19 ID-Nummer
5 Software Examples for Startup
5.1 Preliminary Remarks
For startup we offer you software examples with test code and test
parameters as a download. The software examples support you in making
the first steps and tests with your Micro Automation Set. These sets enable
quick testing of hardware and software interfaces between the products
described in the Micro Automation Sets.
The software examples are always assigned to the components used in the
Set and show their principal interaction. However, they are not a real
application in the sense of a technological problem solution with definable
properties.
5.2 Download
An interruption of the GPRS connection for example because of the
!
assignment of a new IP address by the provider, causes the S7
Warning
block INIT to independently reestablish the connection after approx.
1 h.
The software example is available as download on the HTML page from
which you have loaded the document on hand.
The download consists of a zip.-file which can be extracted with any unzip-
program. The zip.-file contains the following files:
