An application program for a PLC is defined as

Explanation:
An application program for a PLC is the set of instructions that performs a specific control task directly for the user. It contains the control logic that reads sensors, processes the data, makes decisions, and drives actuators to achieve a desired operation. This is the part of the PLC programming that implements the actual process control the user wants, rather than system housekeeping. It isn’t just for general maintenance tasks, nor is it limited to logging data, and it isn’t the startup routine that boots the system. So the description of a program designed to perform a special function directly for the user best captures what an application program is.
