Application
was connected with the pCS via a
LAg simulator, which was supplied
with an I/O list by a CAe system.
the extent of the task can be illustrated
with numbers: In the system,
420 inputs/outputs, 78 measured
values, 36 motors, 77 valves and 70
binary indicators must be controlled
and queried. The visualization system
includes 6 process graphics and 8
system graphics, and the automation
algorithm is handled using 51 control
concept and balance sheet graphics.
In addition, there are 2 step sequencers
with a total of 35 steps and 42
cross traffic variables with other systems.
Successful "test drive" in the office
"this process has brought Lenzing Ag
enormous savings before and during
commissioning," states Bernhard
Voglauer. "180 errors were able to be
corrected in the application software
before commissioning was started."
Actual commissioning then went very
quickly because the process control
system could be ruled out as source
of errors. the programmers were
also able to get through the commissioning
phase without working the
otherwise usual "nightshifts". they
were able to their tasks, such as setting
the parameters for control loops,
limit values and program automats in
the office during the simulation phase
as planned without having to rush.
the possibilities provided by the virtual
test run, including simulating unusual
operating conditions, increase
the quality of the training courses for
the service personnel.

"the time saved and the problems
avoided through virtual commissioning
convinced even the toughest
critics," says Bernhard Voglauer.
mAtLAB ® /Simulink ® is now almost
always used to develop new control
concepts, and the plan is to use the
direct code generation options provided
by integration of Automation
Studio and the latest version of Ap-
ROL.

Shrimp:
more
popular
than ever
Delicious shrimp has taken on
a permanent role in the modern
diet. Step by step, highly-automated
shrimp farms are displacing
traditional agricultural
production facilities. Technical
advancements in this area have
allowed shrimp farms to grow
into a global industry over the
years.
75% of the shrimp from shrimp
farms are produced in Asia. China
and thailand are two of the most
important countries for production.
One of the prominent conglomerates
in this area is the Charoen pokphand
(Cp) group located in Bangkok (thailand).
Cp is one of the largest animal
feed producers in the world for the
aquaculture industries. CP assigned
the company Bitwise, a partner of
B&R for many years located in Brisbane
(Australia), the task of automating
a feed system for aquacultures
in Cikampek (Indonesia). the control
system used was the proBatch from
Bitwise, which is based on B&R technology.
