Ladder Logic Controlling Analog

I was recently on a post that was over 3 years old and only 8 responses. Yet it had almost 8000 views.

When I was programming ladder logic, there were only digital outputs and you had to have a DOS operating system. We did have a timer and a counter.

What are the different ways to control an analog output with ladder logic? Are there any preferred ways or guide lines or standards?

Or is it PLC dependent? Do they have latter functions for this now? Or just an I/O hardware module...
