← TechnologyWhich outcome occurs when a PLC controlling an industrial robot's painting arm experiences a checksum error mid-cycle?
A)Robot arm executes invalid trajectory✓
B)Paints maintain uniform film thickness
C)Process abruptly maximizes energy consumption
D)System seamlessly transitions to other operation
💡 Explanation
The robot arm executes an invalid path because checksum failure indicates corrupted instruction data within the PLC’s memory; the intended trajectory calculation fails using incorrect data, rather than completing normally or gracefully handing off control.
