专利汇可以提供Sequence controller专利检索,专利查询,专利分析的服务。并且PURPOSE: To assure the effective operation of an automatic machine device by storing previously the operating state of the device right before it stops and performing the operation kept on right before the halt of the device when its operation is restarted.
CONSTITUTION: The drive instruction outputted from a control computer 1 via a digital output part 3 is transmitted as a reset signal 7 or a set signal 8 to a control part and converted into a pulse by a pulse converter 11. Then, a reset signal 12 or set signal 13 converted into a pulse is transmitted to a flip-flop circuit 14. The circuit 14 transmits an automatic operation signal 16 subject to an input signal to an automatic holding state deciding part 18. At the same time, a holding signal 6 is also inputted to the part 18. The input of the signal 6 is allowed when the signal 16 is kept ON and then the output of the signal 6 is inhibited when the signal 16 is kept OFF, respectively. Then, a manual operation signal 17 is decided by a manual operation permission judging part 19.
