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:

1 Fields of Application and Benefit
For good comprehensibility, the features of the Micro Automation Set are
explained on the basis of an automation task.
Automation task
As a quality assurance measure, the weight of a delivered quantity of
goods is to be recorded together with a time stamp. These data are to be
sent to a control center via an Ethernet connection and to be archived
there. The control center can be any SIMATIC S7 controller or a PC-based
software PLC. As an example, a PC-based visualization system is to
enable access to the archive data of the control centers. For maintenance
purposes, it is to be possible to directly access the controllers in the
automation network from the office network.

Automation solution – Set 14
The automation solution uses an S7-200 controller¹ with clock cartridge for
acquisition of the process data and for generating a time stamp. The data
records are sent cyclically from the S7-200 controller to a control center²
connected via Ethernet and archived in this control center.
An S7-200, S7-300, S7-400 or a WinAC station are used as alternative
control centers². The archive data of the control center² can be accessed
with WinCC flexible. SCALANCE X108 enables access from the
automation or office network to the individual controllers.

Fields of application
The Micro Automation Set is particularly suitable for use in cost-effective
archiving and communication tasks with low engineering overhead. Any
SIMATIC S7 controllers or SIMATIC WinAC can be used as communication
partners.
The example configuration shown in this Micro Automation Set is used in
numerous applications. The configuration is particularly useful if:
•A lot of data have to be transported
•Quick communication is required
•Existing Ethernet networks are to be expanded with automation
technology (e.g. facility management)
•Programmable logic controls are to be networked over a large area
•The automation network is linked to the office network without causing
an unnecessary load of the office communication sector
•An expandable communication system with open protocol is to exist.
Benefit
•Fast access via Ethernet for archiving or further processing of
S7-200 process data
•Virtually unlimited expansion and usage of the standardized Ethernet
infrastructure, the usage of existing infrastructure is possible
•Open data exchange with PC applications via OPC possible
•Saves time and costs due to quick and convenient configuration,
programming and monitoring (remote maintenance) from a control
center via LAN
•The option of using standard network components enables the use of
wireless LAN (wireless Ethernet), i.e. the visualization PC can be a
notebook and moved freely
•Communication to controllers of higher-level S7 performance classes
and PC-based software PLC by using standard Industrial Ethernet
components and the S7 communication protocol.
