I'm new to PLCs, and have been trying to add a sequence to my ladder program.  Every example I see uses the special function AVsec to initialize a sequence.  Since AVsec is not available for the E10, how do I set up its sequencer?  Can you provide a simple program example of a sequence that runs output 1 for 10 seconds, pauses for 2 seconds, and then runs output 2 for 20 seconds?  I would be most appreciative!
