Upper Computer Development Video Tutorial29

Introduction

An upper computer is a computer that controls and monitors a lower-level system, such as a programmable logic controller (PLC) or a distributed control system (DCS). Upper computers are typically used in industrial automation applications, where they provide a human-machine interface (HMI) and allow operators to control and monitor the lower-level system.

Benefits of Using an Upper Computer

There are many benefits to using an upper computer in an industrial automation application. These benefits include:* Improved operator efficiency: An upper computer can provide a graphical user interface (GUI) that makes it easy for operators to control and monitor the lower-level system. This can reduce operator training time and improve overall efficiency.
* Increased flexibility: An upper computer can be programmed to perform a wide variety of tasks, which gives users the flexibility to customize the system to meet their specific needs.
* Improved reliability: An upper computer can help to improve the reliability of the lower-level system by providing redundancy and fault tolerance.

Types of Upper Computers

There are many different types of upper computers available on the market. The type of upper computer that is best for a particular application will depend on the specific requirements of the application.

Some of the most common types of upper computers include:* Panel-mount computers: Panel-mount computers are designed to be mounted in a panel or enclosure. They are typically used in applications where space is limited.
* Rack-mount computers: Rack-mount computers are designed to be mounted in a rack. They are typically used in applications where high performance and reliability are required.
* Industrial PCs: Industrial PCs are designed to withstand the harsh conditions of an industrial environment. They are typically used in applications where reliability and durability are important.

Upper Computer Software

The software that runs on an upper computer is called SCADA (Supervisory Control and Data Acquisition) software. SCADA software provides a graphical user interface (GUI) that allows operators to control and monitor the lower-level system.

SCADA software also provides a variety of features that can help to improve the efficiency and reliability of the lower-level system. These features include:* Data logging: SCADA software can log data from the lower-level system to a database. This data can be used to track system performance, identify trends, and troubleshoot problems.
* Alarming: SCADA software can generate alarms when specific conditions occur in the lower-level system. This can help operators to quickly identify and respond to problems.
* Trending: SCADA software can display trends of data from the lower-level system. This can help operators to identify patterns and trends in system performance.

Conclusion

Upper computers are an essential component of many industrial automation applications. They provide a graphical user interface (GUI) that makes it easy for operators to control and monitor the lower-level system. Upper computers also provide a variety of features that can help to improve the efficiency and reliability of the lower-level system.

When selecting an upper computer for an industrial automation application, it is important to consider the specific requirements of the application. The type of upper computer, the software that will be used, and the features that are required will all vary depending on the application.
