RE: [CAD_CAM_EDM_DRO] What makes step and dir?

Many PLC's have the ability to do just what you are looking for. Look at
the Automation Direct Website. Programming a PLC is no less user friendly
Than GWBasic. Both require knowledge of the language.

I personally would find it easier to complete this task with a PLC.
The PLC is much more of a "Black Box" solution , and certainly more robust.

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).
