Abstract
PURPOSE: To enable to fetch a number of input signals with a few interruption input terminals without fail, by the bit check for the input line changed in leading in the block of input signal and correcting the data table periodically.
CONSTITUTION: When any in the block of input signal 1 is changed for leading, the computer 3 performs the processing matching with the change in leading of the signal with interruption. That is, when leading signal is present on one signal line of the signal 1, it is detected at the leading change detector 6 and the interruption pulse is inputted to the interruption terminal 11 of the computer 3. This interruption signal starts the interruption program automatically to perform bit-check for the input line having leading change in the block of the signal 1, and the data table is corrected periodically according to the sampling time in the computer 3. Thus, a number of input signals can be fetched with a few terminals 11 without fail.
