Abstract
A production line has a plurality of working groups in which work operations are controlled by a sequential controller. Detectors are provided in each working group of the production line to output signals to a microcomputer. The microcomputer makes sequence patterns for each working group based on data comprised by the signals from the detectors with respect to the order of outputting and the time intervals of the signals. During monitoring, the microcomputer compares signals from the detectors with the corresponding sequence pattern for each working group to monitor the working conditions of the working groups.
