FANUC FANUC System Integration & Peripheral Devices 1 — Questions and Answers
Question 1: Which FANUC communication protocol is most commonly used to connect a robot controller to a PLC on the factory floor?
- EtherNet/IP (Correct answer)
- RS-232 Serial
- USB 2.0
- Bluetooth
Correct answer: EtherNet/IP
EtherNet/IP is the standard industrial Ethernet protocol used by FANUC controllers to communicate with PLCs and other automation equipment.
Question 2: What is the purpose of the FANUC Robot Interface (FRI) in a manufacturing cell?
- To provide a standardized API for external systems to command and monitor the robot (Correct answer)
- To replace the teach pendant entirely
- To manage robot power distribution
- To calibrate robot joints automatically
Correct answer: To provide a standardized API for external systems to command and monitor the robot
FANUC Robot Interface (FRI) provides a standardized software API allowing external applications and SCADA systems to issue commands and read status from the robot controller.
Question 3: When integrating a FANUC robot with a vision system, which function is used to apply the vision offset to the robot's motion?
- VISION OFFSET CONDITION (Correct answer)
- CAMERA CALIBRATE
- TOOL_OFFSET
- JOINT_SHIFT
Correct answer: VISION OFFSET CONDITION
The VISION OFFSET CONDITION instruction in FANUC's iRVision applies the detected position offset from the camera to the robot's programmed motion path.
Question 4: Which FANUC feature allows multiple robots to share the same workspace and coordinate their movements to avoid collisions?
- Coordinated Motion / Multi-Robot Control (Correct answer)
- DCS Zone Limiting
- ROBOGUIDE Simulation
- Cycle Time Optimizer
Correct answer: Coordinated Motion / Multi-Robot Control
FANUC's Coordinated Motion and Multi-Robot Control software allows two or more robots to synchronize their movements and manage shared workspace safely.
Question 5: A FANUC controller's Group Output (GO) signal is used to:
- Send a binary-encoded integer value to a PLC or peripheral device (Correct answer)
- Control individual relay outputs one at a time
- Read analog sensor voltage levels
- Trigger an emergency stop sequence
Correct answer: Send a binary-encoded integer value to a PLC or peripheral device
Group Outputs (GO) in FANUC combine multiple digital output bits to transmit a binary-encoded integer value to an external device like a PLC.
Question 6: What does the FANUC Servo Disconnect function allow an integrator to do?
- Remove servo power from specific axes while keeping the controller active (Correct answer)
- Reset all servo amplifier faults simultaneously
- Switch the robot to a different motion group
- Disable the teach pendant display
Correct answer: Remove servo power from specific axes while keeping the controller active
Servo Disconnect allows individual axes or groups to be powered down for maintenance or tool changes while the controller remains powered and other axes stay enabled.
