← TechnologyWhich control outcome occurs when a PLC's scanning cycle exceeds designed latency tolerances in a high-speed packaging line's synchronization?
A)Accumulated phase synchronization drift✓
B)Optimized predictive feedforward compensation
C)Immediate, safe, system-wide shutdown
D)Increased positional encoder signal fidelity
💡 Explanation
Loss of timing precision occurs because cycle delay introduces timing error above design constraints, causing phase synchronization drift. The PLC misinterprets positional data from quadrature Encoders causing cumulative timing drift rather than immediate halts or higher fidelity, therefore option A is more accurate.
