ABSTRACT:
Disclosed herein is a sequence controller capable of executing programmable sequence operations written in its sequence table. The sequence table comprises a group of input condition collecting instructions, a group of branch condition collecting instructions, a table instruction and a group of input instructions, and has an accumulator for combining such instructions organically and selectively to deal with various sequence operation conditions. Thus it is possible to provide complicated control operations by use of the sequence table. The sequence table also contains a step number storing section which stores the original step number upon transition from one step to another, and a step return performing portion. When a predetermined branch condition is met, the step return performing portion initiates a return to the step stored in the section or to the step next thereto. Thus the error-handling steps are shared among different processes, and the total number of steps in the sequence table is reduced accordingly.
