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 the available Micro Automatic Sets covers a frequently occurring
subtask of a typical customer problem on the low-end performance level.
The sets help you obtain answers with regard to required products and the
question how they function when combined.
However, depending on the system requirements, 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. Please refer to the
respective SIEMENS A&D catalogs for these components.
The Micro Automation Sets are also available at the following link:

1 Fields of Application and Benefits
Automation Task
The freshwater supply of a community is pumped into a reservoir on ground
level using a groundwater pump facility. A controller detects the water level
via a sensor and controls a pump. A temperature sensor monitors the
current pump temperature.
Figure 1-1
Measures for efficient maintenance should be taken for optimizing plant
availability and efficiency.
Alarm messages, such as overheating or due pump maintenance, should
be sent to the service personnel as an SMS message via a GSM modem.
Figure 1-2
Response
Request
Selected process values such as the water level in the reservoir can be
requested by the staff.
Remote maintenance of the controller should be possible. A teleservice
functionality must also exist.

Automation solution  Set 5
For wireless connection of the pump station to a GSM network, the GSM
modem TC65 Terminal is connected with the serial interface of the S7-200
CPU 221.
Fault and operating messages are transmitted to a mobile phone as SMS.
Process data can be requested by the personnel via SMS. The information
is also sent via a short message. Sending the response via telefax or e-mail
is possible.
After the telephone connection with TC65 Terminal has been established
(analog or GSM), it is possible to poll the status of variables and update the
user program with STEP 7-Micro/WIN.
Figure 1-3
The focus in this Micro Automation Set 5 is placed on sending and
receiving of short messages.
All relevant process values such as filling level or operating hours of the
pump are simulated via the user program.
Note
More information on measuring filling levels is available in Micro
Automation Set 3 under the entry number 21689394.
Note
The blocks described here were tested with the GSM modem:
" TC65 Terminal Revision 02.000
" MD720-3 HW version 3.4, FW version 1.7.4

Fields of Application and Benefits
Micro Automation Set 5 Beitrags-ID 21063345
Application Areas
" Remote maintenance, remote diagnostics, remote measurement and
remote control of mobile, remote automatic machines or plant
components
" Distributed tasks in gas, oil and power supply
" Realizing efficient service concepts
" Automatic ordering of material via SMS messages, e-mail or telefax
" Automatic notification of service personnel via SMS
Benefits
" SIMATIC S7-200 sends wireless fault and operating messages via e-
mail, telefax or SMS massage using the GSM modem TC65 Terminal
" Maintenance and service personnel is informed of the plant status via
process values integrated into the message
" Received SMS messages can be evaluated by the SIMATIC S7-200, so
messages can be acknowledged and process sequences be influenced
remotely
" The connection of the controller to the GSM network can also be used
for teleservice purposes. This enables monitoring the current plant
status as well as accessing the control program.
" The TC65 modem can be used in nearly all GSM networks worldwide
world thanks to the quad-band technology.
" By using standard Micro Automation components, automation solutions
offer flexibility to grow with new requirements.
" It is possible to connect the S7-200 controller with PROFIBUS and IE
communication networks by means of an expansion module. This
enables integrating fault and operating messages of already existing
automation plants.

5 Configuring the Startup Software
5.1 Preliminary remark
For the startup we offer you software examples with test code and test
parameters as download. The software examples support you during the
first steps and tests with your Micro Automation Sets. They enable quick
testing of the 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 basic interaction. However, they are not real applications
in the sense of technological problem solving with definable properties.

The basic version "pump station" is activated via the simulator module.
Here the basic library functions can be tested in combination with the
example program of a pump station.
The "visualization station" is operated via a WinCC flexible screen. The PC-
based visualization enables the display of incoming messages of a
connected control with GSM modem.
The functionality of the "teleservice station" is displayed using STEP 7-
