___________ a PLC program puts all outputs in startup state and checks inputs to verify that the process can safely be restarted.

The process referred to in the question is known as "initializing" a PLC program. During this phase, the programmable logic controller (PLC) sets all outputs to a predetermined startup state, which is essential for ensuring that the system is in a known condition before it begins operation. This helps prevent unintended actions from occurring when the system is restarted.

Initializing also includes checking the status of inputs to confirm that all conditions are safe for the startup of the process. By performing these checks, the PLC can identify any potential issues that may cause problems during operation and ensure that the system can be safely brought online. This step is crucial for maintaining the safety and reliability of automated processes.

The other options do not capture this specific function. Stopping involves halting the PLC operations, executing refers to the running of the program without any specific checks for safety upon startup, and resetting typically involves clearing any errors or previous states without ensuring safe conditions for restart.
