EPLAN Volume 01/2001
months. The full version of the Multilift contains around 50
automatically generated circuit diagram sheets, whilst a
complete injection moulding machine contains between 100
and 250 circuit diagram sheets, plus the corresponding lists
and terminal diagrams.
Arburg’s circuit diagram generator was designed in such a
way that it is not always necessary to start again from
scratch with each new injection moulding machine or when
upgrading existing models. Instead, the user simply needs to
modify or supplement the existing routines slightly.
„The effort involved really pays off, thanks to the high quality
of the documentation produced“, stresses Fritz Mattheiß,
„because it allows the customer service engineers to locate
any faults and the affected components far more quickly,
which in turn helps to boost overall customer satisfaction“.
Having started out initially with three EPLAN 21 workstations,
Arburg now has eight systems in use. By the end of the
year 2001, it hopes to have a total of 30 installations to
replace the old system in full.
In future, the circuit diagrams for all five series of Arburg
injection moulding machines in at least five different sizes
will be generated automatically, thanks to the EPLAN 21
system. The hydraulic and pneumatic diagrams can also be
generated automatically with the circuit diagram generator
developed by Arburg, in a direct transferral of the procedure
from electrical engineering.
The circuit diagram generator
will subsequently produce
trilingual documentation
There are also plans for automatic foreign language support,
i.e. translation into the respective local language. The circuit
diagram generator will subsequently produce trilingual
documentation - in German, English and the local language.
„Article alignment with the MRP system, which includes parts
lists as well as the graphical circuit diagrams, is our next target“,
explains Fritz Mattheiß. „To this end, the parts numbers
and article numbers must be read from the MRP system,
which requires allocation between the component in the circuit
diagram and its definition in the MRP system. Initially, we
only expect to be able to implement this as far as module
level, because the different hierarchical levels will make
implementation with the current tools too complicated.“
The company is currently investigating
the option of connection to automatic
labelling systems for labels, stickers
and cables.
The individual projects are archived on
the basis of EPLAN 21 data and additionally
in the form of PDF files, which
are generated automatically. The PDF
files can be viewed from any PC equipped
with standardprograms such as
Acrobat Reader, and can also be printed
out.
Finally, Fritz Mattheiß highlights the
principal advantage of the EPLAN 21
system: „The greatest benefit for the
company lies in the automatic generation
of machine-specific circuit diagrams,
including the relevant crossreferences.
We can depend on the fact
that the documentationis 100 % accurate,
and human error is excluded“.
