How would I use structured text in TwinCat 3 to make a simple simulation of a stoplight/intersection? Red light, green light, yellow light...etc. Please help! Thanks!

This is the question you'll have to answer before ANY serious help will be offered: what have YOU done so far to find a solution?

Tip: search the site, there are examples to be found, if you make the effort.
