I know there's been plenty talk about the low end controllers on here and various other places, but has anybody came across anything about the higher end controllers?

I'm talking the 990/1000 series. I like the look of the 1000 type with the MPG panel, but there seems to be a void of any sort of information about what exactly they're capable of, and how much you can program them to handle things like tool changers. Most listings seem to mention PLC scripts and being able to custom edit them, but that's about as much info as I can find.

SZGH have manuals at http://www.szghauto.com/index.php?c=...&a=type&tid=40
but after having a scan through them, they mention nothing about custom programs. The CNC1000Mdbc(machine centre) manual does cover tool changers at the end, but I suspect quite a bit has been lost in translation.
