Abstract
PURPOSE: To secure the selection for the automatic or manual execution after the emergency circuit and thus secure the optimum control by deciding the presence or absence of the reset command code and the automatic start command code in the program after recovery of the emergency such as the service interruption or the like and then giving the command to the transfer of the process.
CONSTITUTION: Sequence controller 1 consists of input and output interface circuits 2 and 3 which supply and deliver the input and output signals, user memory 4 which memorizes the control program with every process, operation unit 5 and CPU6 which controls the program execution. Thus CPU6 gives shunt to the process number under execution in case the emergency occurs such as the service interruption and the like and then decides the presence or absence of the specific reset command order in the designated program and after recovery of the emergency. And then the CPU presets the process number shunted to the memory to the process counter when receiving the signal showing the presence of the reset command code and then performs the arithmetic process to decide the automatic or manual execution for the process based on the order set previously. In this way, the optimum control becomes possible in accordance with the characteristics of the control subject.
