The AutomationDirect They will drive pulse and direction without any additional hardware, other than the drive. Those bricks even have a (very) simple motion controller feature that are good f0r simple positioning.

I've done exactly what you're describing - CW and CCW with analog speed control - with the '05 before. I've also done a positioning application with the '06. The only difference between the '05 and the '06 (besides more I/O on the '06) is that the '06 has a higher maximum output frequency (7KHz VS 10KHz), so you can drive your motor at a higher RPM, if that's important.
You will need an analog input card for either of those PLC's. 0-10V is easiest to use with a simple pot.

The manual is actually very good at describing the ladder logic setup for controlling the stepper. Ask more questions if you decide to go this route. I'll chime in with what I know.

Hi rpoet,
So maybe a dump question but you still had to write the code for things to work? That is always the weak link/issue as I do kinda understand ladder logic I don't have any good examples of what is needed to follow.
