I would suggest using Modbus. Serial R232 to RS484/422 adapters are common. LinuxCNC supports Modbus in ClassicLadder or with Python and LibModbus. Modbus is designed for machine control and is common on VFDs and with microcontrollers. Search the LinuxCNC wiki for Modbus for more information. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
