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 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:

Application Areas and Usage

Automation Task

For good comprehensibility, the features of the Micro Automation Set are

explained on the basis of an automation task.

In a logistics center, several roller shutters are available for persons and

industrial trucks such as e.g. forklift trucks and other motor-driven means of

transportation.

In order to pass more easily and more rapidly, opening and closing of these

roller shutters is to be automated taking into consideration the protection of

persons and goods. Outside the working hours, it must not be possible to

open the roller shutter except by especially authorized personnel.

Automatic control of the roller shutter is to be realized centrally by means of

a module.

Automation Solution – Set 18

To control the roller shutter, the automation solution uses a LOGO! logic

module with display and integrated date and time function. Three optical

sensors SIMATIC PXO200 connected to the LOGO! logic module ensure

the detection of incoming and outgoing objects as well as of objects in the

hazardous area.

The LOGO! logic module controls the roller shutter motor by means of a

reversing contactor combination consisting of two SIRIUS contactors. The

motor is protected by means of a SIRIUS circuit breaker .

The calendar function of the LOGO! logic module allows locking the roller

shutter outside the working hours. Authorized personnel can activate or

deactivate this calendar function by means of a key-operated switch .
