Answer:
Technician B is correct
Explanation:
In a PLC system, a single output device has malfunctioned and we want to figure out exactly where is that output device is connected. Since the output module indicates that a signal is being sent to the output point where the device is connected then we should check the PLC output rack to locate the point exactly where is the output device is connected. Therefore, technician B seems to be correct here as compared to technician A whose suggestion seems to be more complex and time consuming.
