PROBLEM TO BE SOLVED: To quicken and stabilize control for the purpose of performing initial operation.SOLUTION: In a power supply starting processing, when an initialization processing is to be performed, a CPU transmits an initialization command for initializing respective sub-boards according to an initialization time command transmission table. And besides, when a state restoration processing is to be performed, the CPU transmits an initial command for restoring the control states of sub-boards according to data stored in a back-up RAM area and a back-up time command transmission table. And besides, a special symbol back-up time command table is selected based on a value of a special symbol processing flag stored in the RAM and the initial command is transmitted according to the selected table. By processinging like that, the control for performing initial operation can be quickened and stabilized. |
