Profibus Question & Answers

April 1, 2022 By WatElectronics

This article lists 50 Profibus MCQs for engineering students. All the Profibus Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on their fundamentals Profibus.

A bus is a hardware device designed for allowing data transfer between two or more peripherals by physically connecting to its ports based on its design structure. For safer communication between the devices using buses, there is a number of communication protocols designed.

These communication protocols include inter-system protocols (USB, USART, and UART), intrasystem protocols (I2C, SPI, and CAN), IoT protocols (WiFi, SigFox, MQTT, etc)PLC communication protocols (Profibus, Interbus, Modbus, and more).

A Profibus is a standard communication protocol deployed in PLC-based modules via networks. Profibus is addressed using a DIP switch and is classified into PROFIBUS DP and PROFIBUS PA. Where A PROFIBUS DP is a decentralized type of peripheral, and a PROFIBUS PA is a centralized type peripheral.

PROFIBUS holds the half-duplex type of communication. MSBI, RS485, fiber optics, and RS485-IS are the transmission technologies of PROFIBUS. They are used in the data transformation process and controlling the device in industrial applications. They benefit in terms of usability and flexibility.
