Abstract
Certain exemplary embodiments can provide a system, which can comprise a circuit adapted to cause an actuation of an output device according to a control output. The control output can be generated comprising a control signal, the control signal extracted from a sequence of clock pulses. The sequence of clock pulses can comprise the control signal.
Claims21
A system comprising:
- a circuit adapted to cause an actuation of an output device according to a control output, said control output generated comprising a control signal in a low state, said control signal extracted from a sequence of N clock pulses, said sequence containing said control signal, said sequence received across a clock signal isolation boundary of a programmable logic controller, said sequence outputted from said circuit via a serially coupled pair of inverters.
A method comprising:
- causing an actuation of an output device according to a control output, said control output generated comprising a control signal in a low state, said control signal extracted from a sequence of N clock pulses, said sequence containing said control signal, said sequence received across a clock signal isolation boundary of a programmable logic controller, said sequence outputted from said circuit via a serially coupled pair of inverters.
A machine-readable medium comprising machine-implementable instructions for activities comprising:
- causing an actuation of an output device according to a control output, the control output generated comprising a control signal in a low state, the control signal extracted from a sequence of N clock pulses, the sequence containing the control signal, the sequence received across a clock signal isolation boundary of a programmable logic controller, said sequence outputted from said circuit via a serially coupled pair of inverters.
