the processor and the hardware are as old as we are :} i think the separation of church and state is important... the RT stuff must be isolated from the user front end to the point of separate hardware, just to insure the thought is always enforced some of the GL problems that eliminate so many motherboards will be gone when there is no graphics on the rt 'computer' i think a non-computer is better, pmac fanuc mdsi dont use 'computer chips' they use big xilink and cypress devices or get ti chips foundered for them i understand thats not hobbyist in general or maybe it s better to say its a smaller set of hobbyists but there may be good reason to use vlsi custom, at least the big guys think so also the ui and io can be separate the ui 'AXIS' is a great tool, and it's pretty isolated now >most< io doesnt need rt features >few< io do ( laser on at start of line, pulse sync with distance traveled... ) the so called 'hi-speed' io only offered on TOL control systems. and as far as i can see, the code for the hi speed is NOT in with the 'plc level' stuff. yeh, i think the future of the hardware must be considered in any project that takes this much time & effort to develop hell i'm just putting together off the shelf stuff and its taking months many vendors were not used in my project because they couldnt show me that something would be available for 5 years. The customer insist on it! and some things that could be available, well they werent available here yet ! doh! > > Dave tomp ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
