Re: What makes step and dir?

Thanks for the response Jan. I was hoping to not use the PC due to the bulk of it. Just have some component in the enclosure. I too have no knowledge of the plc.

Can a plc do step and direction or is there another simple way to do
one move and back? Thanks for any input.



Dave: The SIMPLEST way is to use a PC with GWBASIC. You can OUT 888,N:OUT
888,0 Where N is a binary number that STEPS your drives after setting DIR.
OR, you can use a machine-code patch do do that, which you simply CALL from
BASIC.

Yes, a PLC should be able to do this, but not "user friendly", and I don't
have a CLUE how to begin (never fiddled with those).
