PROBLEM TO BE SOLVED: To retrieve whether or not there is a load address which is already used, when the load address is set by comparing the load address stored in a used address state storage part and is already used with a load address while being set at an operation display part. SOLUTION: An address-setting process part 34 stores a load address which is set at an operation display part 31 in a set address storage part 33. A multiplex transmit signal processing part 35 communicates with load control units 10 and 11 to detect a load address while being already used. A used address state storage part 36 stores the load address, which is detected by the multiplex transmit signal process part 35 and while being already used. A set address confirming processing part 37 compares the load address which is stored in the used address state storage part 36 and while being already used with the load address which is being set at the operation display part 31 and in the case that the load address which is being set overlaps the load address which is already used, the display of the effect that the load address set overlaps the load address which is already used, is displayed on the operation display part 3. |
