Which item serves as the programming interface to load ladder logic into the PLC?

Explanation:
The key idea is identifying what actually loads or transfers the ladder logic into the PLC. The programming device is the tool that runs the ladder logic editor, compiles the program, and communicates with the PLC to load the logic into its memory. It serves as the interface between your programming software and the PLC, enabling you to create, modify, and transfer the ladder diagram. The other hardware components have different roles: input modules handle signals from sensors and switches, a power supply provides the necessary electrical power to the PLC and its modules, and the I/O chassis houses the input/output modules that connect field devices to the PLC. None of these load ladder logic into the PLC.
