The safest way to wire a stop button to a PLC system is to use an NC contact programmed to examine for an ON condition.
NC Contact
An electrical contact that remains closed, allowing current to flow, until actuated open, usually referred to as a Normally Closed Contact in electrical circuits.
PLC System
A PLC system encompasses the hardware and software components of a Programmable Logic Controller, including the CPU, input/output modules, power supply, and the programming environment used to automate industrial and manufacturing processes.

Final Answer :
True
Explanation :
Using an NC contact ensures that the circuit is normally closed and the stop button will only interrupt the circuit when pressed, triggering the programmed exam for an ON condition in the PLC system. This allows for a safe stoppage of machinery or processes in case of emergencies or malfunctions.
