Buhler Mechanical Engineer Interview Questions and Answers

Profibus is a widely used fieldbus communication protocol in industrial automation.

• Profibus stands for Process Field Bus.

• It is used for communication between field devices and control systems in industrial automation.

• There are two main types of Profibus: Profibus DP (Decentralized Peripherals) and Profibus PA (Process Automation).

• Profibus uses a master-slave communication model.

• It is known for its high-speed data trans...read more

Troubleshooting Profibus involves checking physical connections, network configuration, and device settings.

• Check physical connections to ensure cables are properly connected and not damaged.

• Verify network configuration settings such as baud rate, parity, and address assignments.

• Inspect device settings to ensure they match the network configuration and are functioning correctly.

• Use diagnostic tools like Profibus analyz...read more

The cable length for PA cables varies depending on the specific application, while the diameter is typically determined by the current carrying capacity and voltage requirements.

• Cable length for PA cables can range from a few meters to several hundred meters, depending on the distance between the PA system and the speakers.

• The diameter of PA cables is usually determined by the current carrying capacity and voltage requ...read more

There are two main types of smoke detectors: ionization and photoelectric.

• Ionization smoke detectors use a small amount of radioactive material to ionize the air and detect smoke particles.

• Photoelectric smoke detectors use a light beam to detect smoke particles in the air.

• Dual sensor smoke detectors combine both ionization and photoelectric technologies for more comprehensive detection.
