<p>A programmable controller of the stored program system which enables even a complex sequence control to be easily executed. A memory (50) stores a first program of the ladder type and a second program described in another programming language such as PASCAL or FORTRAN. First and second setting means (51), (52), respectively, set execution times for processing by the first and second programs. Control means (53) executes the processing according to the first and second programs alternatingly for periods of time set by the first and second setting means (51), (52).</p> |
