ment an operating function. See Chapter 1 for information on how to select operating func-

Modes and Tasks
Operating functions are the elements that comprise Click 500 custom applications. The
Click 500 supports two types of operating functions: modes and tasks.
The list and figure below describe the difference between modes and tasks:
˽ Mode – Consists of a setup function and a mode function. The setup function will run
once, performing initialization and start-up tasks, and the mode function will execute
until interrupted by the user.
˽ Task – Runs once and then restarts the most recently run operating mode.
