Abstract :
A functional test method is proposed for production tests of microprocessor based sequence controllers. The method is based on process flowcharts, in which the operation sequences of sequence controlled machines are defined. The method is applied to a fault detection problem of a commercialized boiler control circuit and the effectiveness is checked
