I like this method! It was easier for me to understand than the SQI and SQO instructions. I like to be able to see what "step" I am in. Thanks for posting
It's an easier approach, but I've seen a lot of people having trouble with it as steps are added, modified, etc. The SQI / SQO is more complex to setup, but it's a lot more reliable in applications with many steps - in my experience.
Also to add on this you should probably build your sequence as a datatype with paramters for steps, messaging, step times, step descriptions, bools for driving outputs etc. then you only need to create a selection tag using that datatype. using the datatype makes it much cleaner. good video btw👍

@9:36, "notice you could use the logic to actuate any valves......." How? show maybe just one output please.
Very good!!
Glad you found it useful Jeff! Let us what topics you want us to cover next.
👍 excelent!
Great video! Thanks :)

That's a good point. You can improve the code in many ways and make it much more readable / usable. Thank you for bringing it up.

Hi mr. Solis, I watched you sequence video and noticed that you use the ONS bit more than once, I was taught that the ONS bit is used only one time.
You're correct, it's best not to use it more than once. It's not a big deal in simple programs, but may become an issue in larger ones.
🥳🥳🥳🥳👍👍👍👍👍
Slow it down please and zoom out a bit. Great video.
