← TechnologyWhich outcome occurs when a PLC controlling a chemical plant's reactor cooling system experiences latch-up?
A)Uncommanded valve closure initiates✓
B)Runaway chain reaction occurs
C)Temperature reading inaccuracies increase
D)Communications protocol failure happens
💡 Explanation
The **latch-up** forces all outputs to maintain their last known state because the PLC logic becomes unresponsive, therefore holding valves at shutdown, rather than allowing proportional control to manage process heat, especially if programmed with failsafe configurations.
