micrologix 1500 sequencer

Has anyone tried to build a 32 bit sequencer?
I have a perfect app for a sequencer but it has 26 outputs.
Thanks

You could as Tom Jenkins says "roll your own", using a counter to index the steps, and a lot of compares and move or masked move instructions.

You can add SQO's in parallel to use more than 16 bits of data.

You can cascade SQO instruction easy enough. Use the DN bit of the first instruction to enable the next.

Thanks guys
I think I'll use the counter and move words to the outputs.
Simple enough, I just didn't think of that.

Just in case you change your mind, here is an simple cascading example.

Thanks again
This will work. I don't know what I wasn't thinking.
