Question

The availability of low-cost microcomputers and programmable logic controllers resulted in a
growing number of installations in which a process was controlled by multiple computers
networked together. The term distributed control was used for this kind of system, the first of
which was a product offered by Honeywell in 1975. In the early 1990s, personal computers
(PCs) began to be utilized on the factory floor, sometimes to provide scheduling and
engineering data to shop floor personnel, in other cases as the operator interface to processes
controlled by PLCs. Today, PCs are sometimes used to directly control manufacturing
operations. Discuss:
2.2.1 The requirements placed on the computer in industrial control applications. (8)
2.2.2 The capabilities that have been incorporated into the control computer to address
these requirements. (8)
2.2.3 The various forms of computer control used in industry.

Answer 1

Answer:- YES this is true that The availability of low-cost microcomputers and programmable logic controllers resulted in a
growing number of installations in which a process was controlled by multiple computers
networked together.

1-The aim of computer control application in the industry is to publish original,high quality products.These computer control application is also used to control the input and output operations.During the 1960s major requirement of computer use in marketing like sales,management accounting etc.

2-Industrial personal computers can be deployed in a industry to perform multiple operation such as manufacturing,security,architecture and machine automation.So PCs has the capabilities that have been incorporated into control computer in the industry to increase the benifits of the industry.

3-There are many form of computer used in industry.

• Rugged industrial PCs:-These industrial PCs offers the best hrdware platform which hepls us for large scale manufacturing that exceed the labour limitations.
• Industrial PC Siemens SIMATIC PC
• Wall mounted industrial PC based on ATX motherboard
• Simatic Microbox PC
