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.

Set14_DocTech_V2.0_en.doc

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.
