摘要： A data error detection method for a bit, byte or word oriented network wherein a protected data unit 46 and an associated data check unit 50 are addressed to a particular field device located on the network, 10 or 26. The data check unit 50 is derived in a particular manner either solely from the protected data unit 46 or from the protected data unit 46 and particular binary codes representing attributes of the network 10 or 26 and the field device sending the protected data unit 46. The particular configuration of the checking data unit 50 is such that the receiving field device or the host 22 can perform a bit-by-bit comparison of either the received protected data unit 46 or data check unit 50 with a protected data unit 46 or data check unit 50 derived in the particular manner by the receiving host 22 or field device 14 or 18.

摘要： A calibration method for a potentiometer which provides indicia reflecting an accurate indication of actual electrical resistance throughout the resistive range of a particular potentiometer. The indicia includes a number of graduation marks or symbols having a range and spacing unique to the resistive characteristics of the particular potentiometer. The indicia is fixed with respect to a known location associated with the particular potentiometer. The range and spacing of the indicia graduations is derived from measured resistance values at predetermined locations along the resistive member of the particular potentiometer.

摘要： A multiplex extender 26 for permitting discrete I/O devices 34, not individually equipped to decode multiplex channel addresses, to be multiplexed on a time division multiplexed control bus 10. The multiplex extender 26 is connected intermediate the time division multiplexed control bus 10 and a branch line 30 and includes a multiplex channel address decoder 78, a data disconnect switch 82 and a branch line controller 90. The multiplex channel address decoder 78 is selectively programmed to one of the multiplex channel addresses of the time division multiplexed control bus 10. The multiplex channel address decoder 78 produces one or more output signals, each being determined by the multiplex channel address which has most recently been decoded. The data disconnect switch 82, connected in series with a data line of the time division multiplexed control bus 10 and a data line of the branch line 30, either passes or blocks the flow of data between the time division multiplexed control bus 10 and the discrete I/O devices 34 in response to the output signal from the multiplex channel decoder 78. A data latch/repeater 86, also connected to the data line of the time division multiplexed control bus 10, selectively stores data from the time division multiplexed control bus 10 or repeats previously stored data to and the discrete I/O devices 34 A branch line controller 90 transmits the previously stored data from the data latch/repeater 86 to the branch line 30 when the data disconnect switch 82 is blocking data frames from the time division multiplexed control bus 10. The multiplex extender 26 can also incorporate a heartbeat pass-through/repeater 94 for passing a heartbeat pulse to the discrete I/O devices 34 during each data frame.

摘要： A current induction arrangement develops a power supply voltage and a measurement signal from current flowing in a circuit path so as to optimize both the energy developed in the power supply and the fidelity of the sinusoidal signal used to measure the waveform in the circuit path. The arrangement includes a capacitor accumulating current to develop a positive voltage with respect to common, a current transformer inducing current from the circuit path and providing an output having a positive induced-current signal component and a negative induced-current signal component. A rectifier circuit is arranged to receive the output from the current transformer, and to produce the positive induced current signal component at a positive output terminal and the negative induced current signal component at a negative output terminal. A first zener diode is connected to receive the positive induced-current signal component, and the circuit permits the positive induced-current signal to charge the capacitor. The first zener diode also has a second terminal coupled to common. A second first zener diode is coupled between the negative output terminal and common via a burden resistor. For developing a measurement voltage corresponding to the current produced by the current transformer, the burden resistor is arranged in series with the second zener diode. The positive and negative induced-current signal components are returned to the current transformers via common.

摘要： A method and apparatus for composing a desirable trip curve, such as an I2*t trip curve, for an electrical protective device from at least one less desirable trip curve, such as an I*t trip curve. The method is accomplished by defining a selected parameter of the desirable overload trip curve and defining the selected parameter as a function of one or more monitored input values, such as current, trip class or phase unbalance, and modulating the selected defined parameter value between a maximum boundary trip curve and a minimum boundary trip curve. The modulated parameter is used to adjust the less desirable trip curve such that it has the characteristics of the desired trip curve. The method is implemented by one or more electrical circuits (filter circuits) representing the less desirable trip curve(s) and composing an output signal representing the desirable trip curve by modulating between the one or more electrical circuits.
