This is an aside to the question that you posed.  There are a couple of
source files for the emc that can help with stuff like tool change and
pallet shuttle.  They are iosh and tkio.  

The file iosh connects Tcl/Tk programs with NML in a very I/O specific way.
 I don't know if you remember the old basic commands PEEK and POKE.  Peek
looked at a pin or address and reported on or off.  Poke stuck a value in
an address. You can do exactly that with iosh.  In fact the little script
IO_Exercise.tcl will do that for you one address at a time.  I believe
that you could get an ISA DIO board and install it, find or set the
board's address and set or view any pin on that board using iosh. 

Then the PLC problem comes into focus.  This is what tkio is -- a PLC
program that uses iosh to run essentially the same machine that is run
using bridgeportio.  The big difference is that tkio is readable
by you and me.  The editing and reading of Tcl/Tk that you have done to
modify the tkemc is sufficient to see and modify the logic of these files.

There is some general information about doing these kinds of things on
the handbook.  Paul Corner has extracted the essential comments from both
iosh and emcsh and they are available on

linuxcnc.org/handbook./part3/emcsh1.html and emcsh2.html
linuxcnc.org/handbook./part3/iosh1.html and emcsh2.html
