I believe EMC doesn't talk to PLC's yet, but appears Steve has just written a Modbus driver so that may change soon. > Could you do something like BCD into EMC from the plc? If your PLC can output BCD on digital output pins, then yes. The turret on my lathe outputs the tool position in BCD on four pins. I used the weighted sum component, wsum, to convert it to an integer.

I did briefly look through the dallur-thc files: http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/configs/dallur-thc/ but it would take a while for me to get up to speed. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
