摘要: First and second processing units execute the same control program to the same input data in parallel. An input/output unit generates the input data and receives one of two output data executed by the first and second processing units. A channel selection unit sends the input data to the first and second processing units and sends the one to the input/output unit by selecting the one from the two output data. In the first and second processing units, a control cycle synchronization unit generates a control cycle signal at a control cycle, a processor executes the control program, a data memory stores operation data including the input data, intermediate data being executed and output data executed by the processor. A diagnostics unit generates summary information by compressing the operation data and comparatively decides whether the summary information matches the other summary information of the other processing unit every control cycle.

摘要: A safety output includes an output controller to make an instruction to output normal output data and first self-diagnosis pattern data synchronously with a control cycle, a normal output unit to output the normal output data synchronously with the control cycle, a test pattern generating unit to encode the self-diagnosis pattern data into a pulse train signal having a pulse width not larger than a preset value and output the pulse train signal in accordance with a baseband transmission system, a combination output unit to combine the pulse train signal with the normal output signal and output the resultant signal, a reconfiguration unit to decode the inputted operation-terminal-portion output signal to reconfigure the operation-terminal-portion output signal as second self-diagnosis pattern data, and a comparator to compare the first self-diagnosis pattern data with the second self-diagnosis pattern data to judge the presence or absence of a difference.

摘要: A multiple-input digital filter capable of filtering a plurality of digital input signals with a single filtering device first latches the input signals and then sequentially selects each of the digital input signals for output to a counter circuit. The counter circuit, which is preset by the previous count value for the corresponding digital input signal, counts up or down depending on the digital input signal. When the count value reaches its maximum, a decision value signal is set for the corresponding digital input signal until the count value for that digital input signal returns to the minimum value. The count values are stored in a shift register which supplies the count value corresponding to the digital input signal as a preset value to the counter. A second shift register stores the decision values corresponding to each of the digital input signals which are then latched for simultaneous output.
