← TechnologyWhich fault arises when checksum errors corrupt PLC ladder logic?
A)Uncommanded robotic arm movements✓
B)Increased power supply harmonics
C)Fieldbus communication errors
D)Stuck-at-fault in the EEPROM
💡 Explanation
If corrupted, instruction steps are altered, because logic solves via altered pathways, resulting in robotic outputs activating incorrectly. This failure stems from compromised integrity, therefore affecting robotic arm actions, rather than power quality issues.
