Seamless documentation of the<br />
production process<br />
the raw materials, usually with some<br />
pre-processing such as grinding and<br />
weighing, are brought in directly from<br />
bags or silos according to requirements.<br />
the entire production process -<br />
from the incoming goods to packaging<br />
the finished products - is completed in<br />
batches.<br />
What makes this type of application different<br />
from conventional plant control<br />
is the volume of data that needs to be<br />
recorded to document the path of the<br />
various materials through the process.<br />
the process steps are variable and<br />
often need to be changed for maintenance<br />
without stopping the process.<br />
the manual interventions must also be<br />
tracked - this is done using pDAs with<br />
barcode scanning capabilities.<br />
Efficient data management on the<br />
PLCs<br />
"Normally this data-intensive work<br />
would be handled by Windows-based<br />
pCs, which would put the plant at the<br />
mercy of a stable pC platform," explains<br />
Jason Zarew, technical Director at<br />
Bitwise and continues: "Our proBatch<br />
system has the capability to store and<br />
manage all this vital information on the<br />
pLC layer. this means the B&R controllers<br />
handle automation of the plant and<br />
also data management. the memory<br />
capacity was one of the major features<br />
of the B&R controllers that made this<br />
application possible. thanks to the<br />
processing power of the Cpus, this<br />
application with 2000+ digital I/Os and<br />
200+ analog I/Os is easy to handle. In<br />
addition, the ability to have so many<br />
independent serial ports made the installation<br />
very cost effective."<br />
the application consists of multiple<br />
servers for redundant data management,<br />
for example for trending and<br />
reporting. the pCs have access to the<br />
large volumes of pLC based data via<br />
pVI. this allows the proBatch servers<br />
to synchronize all this information between<br />
the running system and the SQL<br />
databases.<br />
Remote maintenance saves times<br />
and money<br />
Although the Cp group shrimp breeding<br />
station is in Indonesia, the Bitwise<br />
All processes of the Probatch control system are monitored and displayed in the shrimp<br />
breeding station control room.<br />
Bitwise:<br />
Application<br />
engineers can access the system<br />
whenever required. Fast and easy<br />
maintenance is possible from Brisbane<br />
at any time using either Automation<br />
Studio or if necessary an SQL server.<br />
Increased cost-efficiency<br />
Jason Zarew considers the simple<br />
import of source code into the project<br />
particularly advantageous. Version<br />
management also makes it possible to<br />
easily maintain even very customized<br />
systems. "the amount of programming<br />
required was therefore minimized."<br />
the technical director also notes the<br />
DVFrame library, which is used by external<br />
devices for data exchange. this<br />
is a cost effective method of interfacing<br />
with 3rd party devices such as light<br />
weight indicators, barcode scanners,<br />
and other devices.<br />
