Micro Automation Set 6
Entry ID 22354065
Foreword
Micro Automation Sets are fully functional and tested automation
configurations based on A&D standard products for easy, fast and
inexpensive implementation of automation tasks in small-scale automation.
Each of these Micro Automatic Sets covers a frequently occurring subtask
of a typical customer problem in the low-end range.
The sets help you to 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 by clicking the following link:

Fields of Application and Benefit
Automation task
To provide good comprehensibility, the features of the Micro Automation
Set are explained using the example of an automation task.
In a packaging system, a check for completeness of the packaged goods is
required before delivery. In the course of this quality assurance measure
the goods are to be uniquely identified and all relevant data including time
stamp are to be logged.
It is to be possible to import the log data to Office Excel. The automation of
the logging process and the integration of the required components into the
existing infrastructure of the packaging system are to be possible.
It must be possible to apply the check for completeness of the packaged
goods also to other products with different content without extra work.
The packaging system is to be operated and maintained exclusively via an
HMI device. Operation is to be possible in German and in English.

Automation solution – Set 6
The automation solution uses an
S7-200 controller
and the
SIWAREX MS
weighing module
with
single point load cell
. The weight value of the
packaged goods is captured and compared to a reference value. This
enables to check whether all components are complete. The packages of
goods can be uniquely identified via a batch number.
The integrated time of day function and the
memory module
of the
S7-200
controller
enable a logging of the currently measured weight values with
time stamp.
Interfacing the
S7-200 controller
to a Windows PC using the
PPI cable
enables an automatic readout of the log data. Alternatively to the PPI
connection data can be transferred via Ethernet, PROFIBUS or the
telephone network.
The recipe function of the
S7-200 controller
is used to manage the
reference weight of different production series.
Using a
TP 177micro
touch panel the currently running packaging process
can be monitored by screens providing German-English change language.
