Islands of automation

Islands of automation is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Islands of automation rather than just read about it. In short: Islands of automation was a popular term used largely during the 1980s to describe how rapidly developing automation systems were at first unable to communicate easily with each other. Industrial communication protocols, network technologies, and system integration helped to improve this situation.

Key takeaways

Islands of automation belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Islands of automation to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Islands of automation from memory before moving on to harder problems.

Reference excerpt

Islands of automation was a popular term used largely during the 1980s to describe how rapidly developing automation systems were at first unable to communicate easily with each other. Industrial communication protocols, network technologies, and system integration helped to improve this situation. Just a few of the many examples of helping technologies are Modbus, Fieldbus, Ethernet, etc. It is more recently used by automation specialists to describe a discrete and fully enclosed automated system applied in a largely manual environment. In today's interconnected world it is uncommon for automated systems to be fully stand alone. Therefore, the old usage is defunct and the new usage is more appropriate for companies that wish to automate in a limited fashion.

Worked examples

Example 1 — a first encounter with Islands of automation

Start with the simplest possible case. Write down what Islands of automation claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Islands of automation before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Islands of automation ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Islands of automation

In research: Islands of automation appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Islands of automation in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Islands of automation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer network stubs, Impact of automation, System integration, so understanding it makes those chapters shorter.
In everyday life: Look for Islands of automation outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
