<strong>Beckhoff</strong> | Open automation solutions <strong>for</strong> the packaging industry<br />

The requirements <strong>for</strong> packaging machines are just as diverse as the<br />

properties, <strong>for</strong>mats and materials of the products to be packaged:<br />

apart from hygiene and freshness, which are most important in the<br />

packaging of food, the aesthetics, the presentation design and the<br />

logistics of goods all play a crucial role. Not only that, packaging<br />

design is subject to ever-changing fashion trends, so that packaging<br />

machines must be highly fl exible. In addition to demand <strong>for</strong> small production<br />

lots and higher production speed, traceability and complete<br />

electronic process documentation and validation must be ensured.<br />

Per<strong>for</strong>mance-related control optimises all process steps<br />

<strong>PC</strong>- and EtherCAT-<strong>based</strong> control technology from <strong>Beckhoff</strong> is ideally<br />

suited <strong>for</strong> the automation of the entire process chain <strong>for</strong> individual<br />

packaging machines and complete packaging lines, from fi lling, <strong>for</strong>ming<br />

and sealing to labelling, collecting, re-packing and palletising. For<br />

the packaging machine sector the extensive <strong>Beckhoff</strong> product range<br />

offers high-per<strong>for</strong>mance I<strong>PC</strong>s with motherboards especially designed<br />

<strong>for</strong> industrial applications, compact Embedded <strong>PC</strong>s, a wide range of<br />

electronic I/O terminals, versatile servo drive technology, cost-effective<br />

stepper motor technology, the high-speed EtherCAT fi eldbus, the<br />

TwinCAT PLC and Motion <strong>Control</strong> software, and <strong>Control</strong> Panels as<br />

operating display units. With regard to computing power, complexity<br />

and cost, a scalable control solution can be created <strong>for</strong> any packaging<br />

machine from the integrated modular product range.<br />

More and more functions such as Motion <strong>Control</strong>, Condition<br />

Monitoring, robotics, etc. are moving over into the software and<br />

are controlled by a <strong>PC</strong>, so that the control architecture is becoming<br />

increasingly ‘lean’. In addition, hardware is becoming increasingly<br />

compact, thus decreasing space requirements in the control cabinet<br />

and reducing the physical footprint of the machine. However, <strong>PC</strong> <strong>Control</strong><br />

gives rise to even more advantages: <strong>for</strong> example, the integration<br />

of Condition Monitoring in the controller improves diagnostic options<br />

and simplifi es error handling, as a result of which machine effi ciency<br />

is optimised.<br />

TwinCAT: continuity with <strong>PC</strong>-<strong>based</strong> technology<br />

The universality and openness of <strong>PC</strong>-<strong>based</strong> control technology, in<br />

terms of both hardware and software interfaces, helps machine manufacturers<br />

to adapt their systems to the diverse and ever-changing<br />

requirements without high implementation costs. TwinCAT integrates<br />

PLC and Motion <strong>Control</strong> functions and controls the individual process<br />

steps of the packaging machines with high per<strong>for</strong>mance. Software PLC<br />

programming is <strong>based</strong> on the international IEC 61131-3 standard. A<br />

wide range of software modules <strong>for</strong> different packaging tasks such as<br />

cam plates, synchronisation and interpolating movement of several<br />

axes are available. High-per<strong>for</strong>mance tools such as the TwinCAT CAM<br />

Design Editor and TwinCAT Scope support system design and commissioning.<br />

PLC libraries with function blocks <strong>based</strong> on the PLCopen<br />

Motion <strong>Control</strong> and the OMAC PackSoft standards facilitate programming.<br />

Open communication interfaces support integration into<br />

existing visualisation and control systems. Depending on the requirements<br />

of the automation components, the Windows operating system<br />

enables further software components (in addition to TwinCAT) to be<br />

installed on the same hardware.<br />
