Abstract

PURPOSE: To perform individual processing advantageously by transferring data, bit by bit, normally or, word by word, when abnormality occurs.
CONSTITUTION: Once abnormality is detected, CPU1 is interrupted for abnormality detection. On acception the interruption for abnormality detection, CPU1 sets word-bit assignment signal 6 to a word signal. As a result, several data from input points are fetched at a time by CPU1 as one word. Namely, since data, equivalent to one word, from many input points can fetched by single access, standby processing of proccess data can be performed rapidly. Then, CPU1 normally assigns an address supplied for every input point and fetches data, bit by bit.
