Hello Kenneth, thans you very much for your reply. Is the point, in a tabletop, tha motor stall....in the Huller, we can broke some in the machine.
We can stop the machine one year counting from next Jan. and we have a complete intrumentation setup (Tek scopes digital, and analogs, signal generators, etc), we can programind in C, several assemblys ,and ladders also. my dude is we also have a Sinumerik 880 CNC setup to retrofit it, but the idea of a open platafform is very atractive for me. and we hear someware, many open CNC sell today (enclosed in a industrial PC, like centroid) is heavily based in EMC... so why not tryout...but the dude is i cant find a contrete conversion takes in a big machine (if any kown please tell me). so i think is a important number of small machines running EMC, so this is good due each emc user is a tester so the bugs come out in a collaborative form, opposed a propietary platform, the bugs are cover in forms of upgrades, Services Packs. etc. in a few words , its the EMC safe to use in a industrial enviorement?. i not have the expertise to dilucidated it so as first point i try to make a setup to see the signals. (i have near of 300 plc imputs,and 250 outputs). in my opinions i compare the windows versions versus the linux versions, and i see (in the local market) for the mediun user with Ubuntu cover the most expectations. but for a minority not due for the availity of specific software. i need to posicionate my proyect is a medium, or is a speciality. the litle reading in EMC, open my mind for a new form of solve the machine, so this new form also have points to dilusidate. principally in hardware issues. with EMC we can spend more money in the man hours to implement it, as opossed with a "box" solution the spend ins the Hardware and the specific "licences" to be implemented. The bad is the tech cycle is shorted, so the things come obsolete fast so if we install a Sinumerik 840D in the mean 4 or 5 years, they come obsolete, and the pianfull to get spares is grow, this its the leitmotiv of my aproach to EMC. I are open to any suggetions to my proyect. DAY 0. thansk Juanjo Monday, December 17, 2007, 4:05:19 PM, you wrote: KL> This type of conversion should be doable; but it will be a big job.
