FANUC FANUC System Integration & Peripheral Devices 3 — Questions and Answers
Question 1: What is the recommended method to transfer TP programs from one FANUC controller to another?
- Use the FILE menu to save/load programs via USB or FTP from the controller (Correct answer)
- Re-teach all positions manually on the new controller
- Copy files using a third-party FTP client directly to the robot's hard drive
- Use the ROBOGUIDE simulator export function only
Correct answer: Use the FILE menu to save/load programs via USB or FTP from the controller
FANUC controllers have a built-in FILE menu that allows programs, system variables, and configuration data to be saved to USB or transferred via FTP.
Question 2: In a FANUC cell using PROFINET IO, the robot controller is configured as a:
- PROFINET IO Device (slave) communicating with a PROFINET IO Controller (PLC master) (Correct answer)
- PROFINET IO Controller polling other field devices
- PROFINET IO Supervisor for network diagnostics only
- PROFINET Proxy bridging to EtherNet/IP
Correct answer: PROFINET IO Device (slave) communicating with a PROFINET IO Controller (PLC master)
FANUC robots configured for PROFINET operate as IO Devices (slaves), with the Siemens or other brand PLC acting as the IO Controller (master).
Question 3: Which FANUC feature enables the robot to automatically slow down its speed when a person enters the collaborative workspace?
- Speed and Separation Monitoring (SSM) via DCS (Correct answer)
- Automatic Speed Limit via WAIT instructions
- Force Torque Sensor speed override
- PLC-driven speed select register
Correct answer: Speed and Separation Monitoring (SSM) via DCS
Speed and Separation Monitoring (SSM), part of the FANUC DCS safety suite, automatically reduces robot speed proportionally as a person approaches the robot.
Question 4: When setting up FANUC iRVision for 2D part location, what calibration step is required before the vision process can output accurate offsets?
- Camera calibration to establish the pixel-to-millimeter mapping for the robot's work plane (Correct answer)
- Tool center point (TCP) calibration only
- Joint mastering of all robot axes
- Payload identification routine
Correct answer: Camera calibration to establish the pixel-to-millimeter mapping for the robot's work plane
Camera calibration in iRVision maps camera pixel coordinates to robot world coordinates, which is essential for accurate position offsets to be applied to motion.
Question 5: Which FANUC controller feature allows an operator to monitor and adjust robot program registers remotely from an HMI or SCADA system?
- Web Server (iRWeb) or Socket Messaging interface (Correct answer)
- Local teach pendant only
- FANUC CNC DNC file transfer
- HART protocol fieldbus
Correct answer: Web Server (iRWeb) or Socket Messaging interface
FANUC's built-in web server (iRWeb) and Socket Messaging interface allow remote systems to read and write program registers, I/O, and status data.
Question 6: A FANUC R-30iB controller's Error Recovery function (RESUME) is designed to:
- Allow the program to continue from the interrupted position after an alarm is cleared (Correct answer)
- Reset all system variables to factory defaults
- Re-teach the last recorded position automatically
- Perform a full power-cycle of the controller
Correct answer: Allow the program to continue from the interrupted position after an alarm is cleared
The RESUME function allows the robot to recover gracefully from an interrupted motion by continuing the current program line after the operator clears the fault and confirms it is safe.
