← TechnologyWhich consequence results when PLC cycle time exceeds scan duration in robotic cell?
A)Inconsistent sensor data acquisition✓
B)Excessive drive train lubrication needs
C)Regenerative braking system overload
D)Robot encoder phase shift occurs
💡 Explanation
Missed I/O updates lead to inconsistent sensing, because timing is critical for the distributed control; therefore, the inaccurate robot path results rather than controlled momentum, as the **cyclic redundancy check** error goes unhandled by the delayed PLC.
