What are the steps involved in basic I/O testing with the Teach Pendant?

• A. Toggle outputs, monitor inputs, and ensure expected responses.
• B. Calibrate the robot's axes and rehome.
• C. Update firmware, run a diagnostic, and save logs.
• D. Load a new tool and test offset.

Answer: (A)

Testing basic I/O on the Teach Pendant centers on the live feedback loop between outputs and inputs. You energize or deactivate a digital output and then watch the corresponding input or status indicator to confirm it changes as expected. This verifies wiring correctness, I/O addressing, and that the devices (sensors, indicators, and other signals) respond properly to the control signals. While you toggle outputs, look for correct state changes, no stuck or phantom readings, and proper return to idle when the output is off. This direct check of the I/O path distinguishes it from tasks like axis calibration, firmware maintenance, or tool offset tests, which involve positioning, software health, or tooling geometry rather than the basic control-and-sense loop.
