I was wondering how I might go about using my sequencer in such a way that I can set a time at each step or positon in the sequence. What will be the easiest way to do this?

ex:

step 1=2sec
step 2=6sec
step 3=7sec
etc...
 
...the sequencer step bit enables the timer...the timer DN bit steps the sequencer...
BTW, my sequencers these days are almost always an "add 1 to a register (N7:0, say) when the step is true" type and the decoded step bits are generated by an unconditional coil with the address B3:0.[N7:0] just include a fle fill function immediately before the coil to clear the unaddressed bits. A very simple sequencer. For multiple times, load just one timer indirectly using the current step number to pick a time from an array.
