Abstract

PURPOSE: To lessen the burden of CPU to supply the analog data in case the dispersion of the input data caused by the temporary noise or the like is detected through comparison between the input data and the correct data after scanning in the fixed times via the scanner.
CONSTITUTION: A number of input points of signal conditioner 1 and 2 are scanned by scanner 3 and 4 with switching, and the fixed input analog data is selected based on the command given from CPU7. This selected data is converted into the digital data via D/A converter 6. Then control part 8 is provided with the output of converter 6 used as the input, and input/output bus interface control circuit 10 is provided at part 8 along with comparator 16 which compares the digital signal with the correct data memorized in memory part 15. In addition, retrial data register 11 and retrial counter 13 are installed to carry out the retrial in case the comparison result of circuit 16 is not correct. Thus, the retrial is given in the fixed times through counter 14, and the data obtained through the retrial is transferred to CPU7 when the data is within the allowable region.
