Nov.4 Touch Sensor as Button Applications

E_CYCLE is better to use than E_DELAY in many cases:

• E_CYCLE: Sends sample request at regular intervals, independent of other FBs
• E_DELAY: Waits a specific length of time. A total sample cycle time can be influenced by the time variance in FB execution times.

Simple example: Touch sensor as start application button 
E_CYCLE + E_PERMIT

E_SWITCH+E_DELAY
