Abstract
Progressing conditions of sequence control are taken as patterns of input/output data, and a plurality of status patterns are set separately from user programs. The status patterns are expressed by a ternary of ON, OFF and EITHER ON or OFF with respect to all the input/output data. When the status pattern at the time of actual control coincides with the set status pattern, the discrimination number of the pattern is displayed.
