Hello Guys, Thanks you very much for your support.

I not say "i not want to use Ladder" , i need program a control
routine to move the tool robot, due i not see a easy way to do
it in ladder (tranforming a Txx comand into a Cartesian coordinate
for example) the othe parts of the machine fit well in ladder like
tha Pallet changer or Doors logics. (for my HMM Huller nbh-150)

The Sinumeric Implementation, relly a 10% in ladder the remain
in S5 assembly (a hard one, i amaizing the complejized in this
programing lenguaje,by lucky i want to stay far away)

Now i have the Racks of the sinumerik put side to side
to le EMC2 box, also i have a lot of Docs., and i try to
make a Diagram of the Control Routine. i have a 50% of the job
complete, but in the robotic part i get a wall.

Also i study to put another EMC2 box controlling only the Robot
and sinchonizing via a serial comunications (so i need to write a
special comunications routine to comunicate the Boxs, and "C" come
again to mind).

The "B" axis is another pain.
Due is a Hirt ring system, i need to lift the table before to Rotate
to the commanded value, so i need to "trap" the rotate table, as i no
nned to interpolate this axis, i study to make a subroutine to do the
job.

So... i read the Integrator manual, and try to write a simple routine
to test my ideas.

Any idea is wellcome

Thanks Again

Juanjo
