Many options exist and a quick google will net several to choose from.
Here's one I just tripped on:

To me, it's a bit of a mess and the choice to make is based on economics of
development time and long term support rather than purchase price.
There's a fairly large existing support base for real PLCs in industrial
settings. Arduino... not so much.
