Delighteck Technologies - Industrial Protocols

PLC (Programmable Logic Controller):

PLC is like a small computer used in factories to control machines automatically.

Use Case: In a biscuit factory, a PLC can control the baking time to make sure biscuits are cooked perfectly every time.

SCADA (Supervisory Control and Data Acquisition):

SCADA is a system that helps people see and control processes in big plants or factories from one place.

Use Case: In an electricity plant, workers use SCADA to watch the power flow and make sure everything's running smoothly.

DCS (Distributed Control System):

DCS is a big control system in factories that manages many parts of the production process together.

Use Case: In a big oil refinery, DCS makes sure all steps, from cleaning crude oil to making petrol, happen properly.

Profinet:

Profinet is a language that machines in factories use to talk to each other fast.

PROFINET is an open Industrial Ethernet solution based on international standards. It is a communication protocol designed to exchange data between controllers and devices in an automation setting

Use Case: In a car manufacturing unit, one robot can tell another robot to start painting a car using Profinet.

OPC-UA (Open Platform Communications Unified Architecture):

Unified Architecture machine to machine protocol for Industrial Automation. Developed by OPC Foundation Standardized Secure Time Series Data, Alarms, Events Client Server Architecture

OPC-UA is a common language for machines from different companies to understand and talk to each other.

Use Case: In a sugar factory, a machine from Company A can work in sync with another machine from Company B using OPC-UA.

Frequently asked questions

Q: What is a PLC?

A: A PLC is like a small computer in factories which controls how machines work.

Q: Why do factories use PLC?

A: Because PLCs make machines work automatically without needing a person to operate them all the time.

Q: What does SCADA mean?

A: SCADA is a computer system that helps people see what's happening in a big factory and control it from one room.

Q: Why is SCADA useful?

A: It helps in checking and controlling many machines at once without going to each one.

Q: What's the role of a DCS?

A: DCS is used in big factories to manage and control different parts of the production together.

Q: Is DCS different from SCADA?

A: Yes, while SCADA looks over the whole factory, DCS focuses on managing different parts of a big production process.

Q: What is Profinet?

A: Profinet is a fast way for machines in a factory to talk to each other and share information.

Q: Why do industries like Profinet?

A: Because it helps machines work together smoothly and quickly.

Q: What does OPC-UA do?

A: It's a language that lets machines from different companies understand and talk to each other.

Q: Why is OPC-UA special?

A: Because it allows different machines, even from different brands, to work together without problems.
