PURPOSE:To improve maintenance efficiency, by providing an IPL (initial program load) control device in the remote station to perform IPL of the remote station from the center station. CONSTITUTION:If contents of memory 210 are destructed in remote station processing device 21, the IPL request signal is transmitted from transmission part 2211 to the center station through line 3. The center station transfers the program to memory access part 212 through gate 2214 after a fixed time. In memory access part 212, the received program is written into memory 210 through write part 2121. Consequently, since IPL of the remote station is performed from the center station, the file memory of the remote station is omitted to improve the maintenance efficiency. |
