PROBLEM TO BE SOLVED: To make an exclusive operator or an exclusive system management engineer unnecessary, to reduce the system cost, and to avoide a useless time of a worker. SOLUTION: While plural stopping positions are set on a conveyer route, and child machines 6 are set to the stopping positions, a parent machine 1 is set to a conveyer device to move on the conveyer route so as to carry out the communication with the child machines 6, and it is decided whether the conveyer device is in the waiting condition or not by the parent machine 1, so as to control the conveyer device to move on the conveyer route according to the calling request from the child machines 6. Since the calling can be carried out from the child machines 6 at the stopping positions, an exclusive operator or an exclusive system management engineer is made unnecessary, and a useless time to seek the conveyer device by an operator can be avoided. Furthermore, since the display of the input and the condition of the calling is carried at the child machines 6 side, while only the decision of the condition and the movement control according to the calling are carried out at the parent machine 1 side, the system can be realized at a low cost. |
