The company Dr. Wiewelhove in Telgte,

Westphalia, has designed and built what

is now the largest empty bottle sorting

plant in Germany for Bier Schneider in

Dortmund. The plant which covers a

surface of 60 x 30m over three floors

identifies and distributes up to 6,000

crates of every possible type every hour

to a maximum of 14 stations.

AS-Interface is used to link the signal I/O

of the sorting equipment to four

SIMATIC S7-300s. The CP342-2 com-

munication processor is the master and

provides the link between the CPU of

the controller and the AS-Interface. More

than 100 digital modules each with four

digital input signals connect the sensors

distributed around the plant with the

controllers. For the most part, these are

Photo Electric Cells that ensure that

there are no jams. Two masters are

used for each controller, which means

that a total of eight AS-Interface lines

with a maximum cable length of 100 m

is sufficient for the entire I/O cabling.

20 pneumatic AS-Interface compact

modules also operate in the plant. By

reducing the entire installation to a few

cables, such as AS-Interface, com-

pressed air and emergency stop cir-

cuits, considerable areas of the plant

could be standardised. One important

aspect for H. Pelz, head of electrical de-

sign at Dr. Wievelhofe, were the huge

savings on assembly and installation

that AS-Interface made possible: “AS-

Interface made it possible for us to as-

semble a plant at low cost on schedule,

the reduced configuring phase being an

important factor.”

Germany’s largest

bottle sorting plant

which covers

a surface of 60 x

30m on three floors.

A total of 8 AS-

Interface lines all

with a maximum

cable length of

100 m provide full

I/0 cabling.
