Oscillating pulse

SB 3 is a built-in 1 second pulse oscillator that generates a 1 Hz pulse.  SB 7 generates a 1 Hz pulse every 100mSec.

You can link these SBs to a:

• Direct Contact

• Inverted Contact

• Positive Transition Contact

• Negative Transition Contact.
   

The following example shows a counter that increments by one at each one second pulse.
