In order to safely command and control the machinery used in
the system, OBIAL uses the MCC Boards and PLC-SCADA system produced by OBİ-Electrics.
While MCC Boards are used in simple grain storage systems, OBIAL recommends
PLC-SCADA systems in bigger and more complex systems.
While the MCC boards require the manual operation of the
system, PLC-SCADA requires no expertise since it allows fully automated
control. OBIAL prefers world-known and reliable high quality brands including
Siemens,
Schneider Electrics (Telemecanique), and Phoenix Contact in
switching materials for the command systems of both the PLC-SCADA and MCC
boards. The PLC-SCADA command system supplied by OBIAL allows for controlling
and managing the entire system from a single point. Thanks to the software
custom-developed for grain storage systems, all potential errors of the
operator are estimated in advance, making the system protected against human
errors.
The operator is warned by the system to identify and remedy
possible failures in running equipment and power boards with the exact position
of the failure, allowing for immediate response.
The software shows the system’s actions so it becomes
possible to respond to the system. The system is automatically interrupted and
emergency stops are possible with Emergency buttons against potential dangers,
which ensures maximized personnel safety. Since the system is operated in a
certain order and by certain time intervals in conveying all types of grains,
any potential failures otherwise (grain clogging the system and resulting
physical breaks and failures in system elements caused by overload) are
prevented at the onset. The ability to monitor and use the system, and detect
failures over the internet saves time both on the customer and OBIAL side in solving
the problem. The ability to control the command panel on 24V and the insulated
structure of the command system and the power board prevents the system from
damages in case of failure. With PLC-SCADA, only the motors needed for the
intended work shall be operated, preventing unnecessary motor operation and
saving energy. Since the switching materials used in the system are, as
mentioned earlier, supplied by world brands allowing easy access to spares in
any part of the world, potential failures in command systems can easily be
remedied in a short time. The command system is designed with industrial and
highly resistant products, which eliminate potential damages to the system
caused by external factors including harsh operational conditions, humidity,
high temperature etc.
