Project Implementation:
Conclusion:
UNO-2050E is in this project primarily used as a highly stable and functional embedded platform. UNO-2050E not only has the
same capabilities and flexibilities of a traditional PC, but it also overcame the three biggest problems of computer system in this
industrial environment. First of all, an unreliable fan system can fry the internal circuit, causing downtime that hurts productivity.
Second, the spindle of a HDD can not work properly in vibrating environments. Lastly, the flow of power will create an enormous
amount of heat. UNO-2050E's fanless, anti-shock and anti-vibration design is the perfect solution for such a hostile environment.
Equipped with two LAN ports, UNO-2050E not only collects sampling data using Modbus/TCP, but also transfers this data to the
server through the Intranet. So it works like an intelligent device between two networks. Installed on the CompactFlash card is the
embedded version of Windows CE .NET, which has built in SQL components so that management can search through the da-
tabase remotely. To simplify the operator’s usage, a set of simple control keys are connected to 2050E's 4-channel digital I/O for
simple control commands.

Improving Reliability of Monitoring Systems in the
Iron and Steel Industry
Facility Management
China
Project Introduction:
Most iron and steel processors have already implemented monitoring systems that use traditional PCs
or controllers for data samplings. But traditional PCs have often had problems with the rough operating
environment of steel and iron mills. A customer in China wanted to create a more reliable, but also efficient
monitoring system to replace their old system. UNO-2050E proved to be the right solution after matching
all the critical requirements.
System Requirements:
The main challenge with monitoring systems in iron and steel mills is the large volume of sample data,
and the extreme environment. Traditional PCs often become unstable in these conditions, and these older
systems can rarely be trusted to provide reliable monitoring data. The customer therefore wanted to create
a new system based on an industrial PC that could withstand tougher environments, and at the same time
provide good computing performance.
System Description:
With the implementation of UNO-2050E in an iron and steel manufacturing system, all the pump station
data can be sampled through an Ethernet network using Modbus/TCP communication. The PLC monitoring
control for manufacturing processes can also be connected to UNO-2050E through an RS-485 network.
Local storage is done by a vibration-resistant CompactFlash card, while the monitoring data is simply
collected and transferred to a secured SQL server for storage. Through the factory intranet, management
can monitor, control and search for specific data.
A set of control buttons is connected to the 4-channel digital I/O interface of UNO-2050E, so if the system
detects an alert, operators can quickly deal with the situation via the control keypad.
