for example for material and surface
refinement (e.g. mirrors, headlights,
automobile rims) or as a functional
layer for optics (e.g. thin film polarization,
glass for protecting against
heat).
evatec offers different process
modules that can be roughly differentiated
as batch process modules
(multiple sources) and single process
modules. In a production plant,
these single machines can be freely
arranged according to the customer's
requirements using the building
block principle.
PC-based controller
each of these processing units is
self-contained, i.e. each machine
has its own controller, in this case
an ApC620 with a CAN, DeviceNet
and pOWeRLINK interface. the controller
takes over responsibility for
controlling and monitoring all sensors
and actuators including motion
control. A batch process module
with 5 sources has approximately 50
valves, 30 DeviceNet components
such as vacuum gauge heads and
gas flow controllers as well as 7 servo
axes for various positioning tasks.
Common tasks such as controlling
pumping procedures and monitoring
the safety circuit are achieved using
an X20 controller together with a
SafeLogic controller.
A pC operator station used as higherlevel
system also functions as a communication
interface to the entire
Evatec:
Application
Implementation of any combination of batch and single-process modules provides customers the highest level of flexibility when planning
and creating their systems.
This innovative process is also used, for example,
to apply a functional layer for optics.
production plant (host connection).
Communication to the individual
machines was implemented with pVI
(process Visualization Interface) using
.Net controls. the capability to
configure the system was also given
great importance here, and a system
was developed that leaves nothing to
be desired.
Simple integration of 3rd party
devices
the B&R hardware platform has proven
itself again and again to be a modern,
fast and flexible control system.
With this project however, there was
a new twist that had yet to be fully explored
- the ability to work openly with
3rd party devices and bus systems.
No less than five different interfaces
have to be integrated here because
many special devices are used in the
industry and the availability of alternative
fieldbus connections is limited.
these many different systems could
be easily integrated into the B&R system,
in particular because of the new
functions that are available and full
integration in Automation Studio.
A further highlight when implementing
this project was the use of the
new Safety controller and the X20
Safety I/O modules belonging to it.
The continuity and flexibility that
could be achieved with this system
can hardly be found on the market
with another manufacturer. Above
all, the various operating modes
and the many configuration options
implemented here would have been
impossible using hardware.
