Timer and Counter Instructions Section 3-6
Example 4:
One-shot Bit
A TIM timer can be combined with OUT or OUT NOT to control how long a
particular bit is ON or OFF. In this example, CIO 000204 will be ON for 1.5
seconds (the SV of T0001) after CIO 000000 goes ON.
Example 4:
Flicker Bit
The following program examples show two ways to create flicker bits. The
second example just mimics a clock pulse.
Two TIM Instructions
Two TIM timers can be combined to make a bit turn ON and OFF at regular
intervals while the execution condition is ON. In this example, CIO 000205 will
be OFF for 1.0 second and then ON for 1.5 seconds as long as CIO 000000 is
ON.
