1. A method for distributed machine control, comprising:

  • controlling a first actuator with a first control module, said first module including a first processor carrying out a program of instructions and generating a first set of signals for controlling said first actuator;

    controlling a second actuator with a smart camera module, said smart camera module including a second processor carrying out a program of instructions and generating a second set of signals for controlling said second actuator;

    linking said first set of signals through a first error current block disposed in said first module to said first actuator, said first error current block receiving and transmitting an error current loop signal and interrupting said first set of signals if said error current loop signal is interrupted;

    linking said second set of signals through a second error current block disposed in said smart camera module to said second actuator, said second error current block receiving and transmitting said error current loop signal and interrupting said second set of signals if said error current loop signal is interrupted;

    detecting an error condition; and

    interrupting said error current loop signal upon detection of said error condition.
