CONTROL PROGRAM MANAGEMENT DEVICE, INFORMATION PROCESSING DEVICE, AND CONTROL PROGRAM PROCESSING METHOD

The invention relates to a control program management device, an information processing device, and a control program processing method. The control program management device includes a storage unit, a transmitting unit, an updating unit, and a retaining unit. The storage unit stores therein a control program executable by a controller of a control apparatus. The transmitting unit transmits the control program to an information processing device. The updating unit updates, when the control program is transmitted to the information processing device, a permission so as to prohibit another information processing device from editing the transmitted control program. The retaining unit retains, based on information transmitted from the information processing device when the control program is transmitted to the information processing device, unique information identifying the information processing device and the transmitted control program. The transmitting unit further transmits, to the information processing device identified by the unique information, an inquiry of whether the information processing device is editing the control program identified by the unique information. The retaining unit further deletes the unique information when it is determined as a result of the inquiring by the transmitting unit that the first information processing device is not editing the control program. The updating unit further release the permission so as to permit another information processing device from editing the control program when it is determined as a result of the inquiring by the transmitting unit that the information processing device is not editing the control program.
