SIMATIC ET 200S COMPACT

Meyer Burger AG, Switzerland –

Manufacturing and processing of materials

Requirements

Meyer Burger AG has over 50 years of experience in cutting

hard and brittle materials and special crystals such as silicon

and sapphire. The global sales and service network of Meyer

Burger has a separate subsidiary in China and Japan as well as

service centers in Germany and the Philippines. The main in-

dustries are the photovoltaic, semiconductor and optical and

ceramics industries. More than 3,500 systems have been in-

stalled worldwide.

Hard and brittle materials have to be cut faster, more accurate-

ly and with less loss of material. This places stringent demands

on the control system and the I/O: Compact size, fast re-

sponse, reduced wiring outlay and modular construction of

machines.

Solution

To meet these requirements, Meyer Burger relies on the com-

pact distributed I/O ET 200S COMPACT. Thanks to their high

channel density, it was not necessary to expand the stations.

Add-on terminals were also used to enable 3-wire connection

without the need for additional terminal blocks. This saves

space and time during wiring up. The existing bus system was

PROFIBUS DP, so this was also used for the new solution.

Benefits

The use of ET 200S COMPACT provides several benefits: The

signals of the different sensors and switches can now be bun-

dled and evaluated by the existing PROFIBUS. Complete preas-

sembly (wiring) of the modules means that on final installa-

tion only the bus cable has to be connected. Time-consuming

wiring of modules in the control cabinet is therefore reduced.

"By using ET 200S COMPACT, we can acquire control variables

on our machines decentralized and transfer them to the con-

troller over PROFIBUS. Fewer signals therefore have to be

routed to the control cabinet. This reduces the wiring costs

and increases our flexibility considerably. We can therefore

reduce throughput time at final assembly."
