  HOME               UNIT 1             UNIT 2            UNIT 3           UNIT 4             UNIT 5 SCADA SCADA (supervisory control and data acquisition) is a category of software applications for controlling industrial processes, which is the gathering of data in Real Time from remote locations in order to control equipment and conditions. SCADA provides organizations with the tools needed to make and deploy data-driven decisions regarding their industrial processes. One of the most commonly used types of industrial control system, SCADA can be used to manage almost any type of industrial process. SCADA systems include hardware and software components. The hardware gathers and feeds data into field controller systems, which forward the data to other systems that process and present it to a human-machine interfac...

It is designed as an extremely lightweight publish/subscribe messaging transport that is ideal for connecting remote devices with a small code footprint and minimal network bandwidth. MQTT today is used in a wide variety of industries, such as automotive, manufacturing, telecommunications, oil and gas, etc. MQTT protocol MQTT stands for  Message Queuing Telemetry Transport . MQTT is a machine to machine internet of things connectivity protocol. It is an extremely lightweight and publish-subscribe messaging transport protocol. This protocol is useful for the connection with the remote location where ...

The protocol is targeted for Internet of Things (IoT) devices having less memory and less power specifications. As it is designed for web applications it is also known as "The Web of Things Protocol". It can be used to transport data from few bytes to 1000s of bytes over web applications. It exists between UDP layer and Application layer. Following are the features of CoAP Protocol: • It is very efficient RESTful protocol. • Easy to proxy to/from HTTP. • It is open IETF standard • It is Embedded web transf...
