Briefly, mostly yes. The S word has an associated HALpin. This HALpin can be HAL connected to another HALpin that handles the hardware that can affect your VFD speed function. So: > S word --> S word HALpin --> 20ma HALpin/20ma HALcomponent -- 20ma hardware > ^^ g-code/MDI -- .hal configuration file -- HAL .comp component file -- wire > from hardware interface to VFD In other words, LinuxCNC already has a S word HALpin that you can use to connect your 20ma interface to. You would need to decide what hardware you want to use and look for or make the HAL component (software). -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
