of the LB 25, we already need more
than 210 inputs and outputs for the
integration of sensors and actuators.
Here, conventional connection
technology would not only result in
substantial wiring and time expenditure,
but would also be more prone
to errors."
that's much different with a busbased
I/O system like the one from
B&R: It reduces wiring to a minimum,
and therefore also potential
sources of errors. "With the prefabricated
lines of the X67 system,
wiring errors are nearly impossible
and modules are exchanged according
to the plug&play principle," says
thomas Ziemski happily. "that results
in faster installation and shorter
downtimes, even though a good bit
of software knowledge is required
for bus system diagnostics."
Additionally, the B&R solution can
easily be expanded, and therefore
the optional peripherals for the machines
can also be integrated, as
thomas Ziemski describes: "to do
this, we only have to install an additional
I/O module and connect it
with the rest of the I/O system using
a single X2X line."
Simple connection to different
control environments
The company also benefits from the
fact that the X20 System includes
various bus controller modules that
allow the I/O system to be connected
to the controller using all wellestablished
fieldbus systems. "Many
of our customers insist on certain
control manufacturers depending
on the region where the customer is
located. We have to be able to install
controllers from different manufacturers,"
explains thomas Ziemski.
"Here, B&R not only offered the suitable
controller modules, they also
provided competent and committed
support when creating the necessary
software for implementation of
the I/O system in our machines."
With the exception of its smallest
machines, Laempe & mössner
has already changed over its entire
product range to B&R I/O systems.
"Because of the advantages offered
by a uniform architecture, for example
regarding maintennace, we are
in the process of changing over the
remaining machines to B&R technology.
It's only a matter of time," says
thomas Ziemski.
Laempe:
Application
Because the machine is operated in harsh environments (such as foundry workshops),
Laempe places their trust in B&R components, which are extremely robust
and reliable.
The open fieldbus interfaces
on X20 System
devices allow connections
to be made to
nearly all 3rd party devices.
