換せずには変更できないという欠点がある。In the system described in Japanese Unexamined Patent Publication No. 53-2051, the initial program load (referred to below as r) is included in the communication information.
This information communication is treated as one of the normal information communication control procedures between the master station and the remote station, and the line control that constitutes the IPL system is included. The department needs to analyze the information received from the master station. Therefore, the line control unit requires a microprogram-controlled processor for information communication control.
Information and communication control procedures are stored in a continuous memory that will not be erased (
It is usually programmed into a ROM. For this reason, there is a drawback that the information communication control procedure cannot be changed in the future without replacing the successive memory.

欠点は解消される。On the other hand, in the system described in Japanese Patent Publication No. 58-57955, after an IPL request comes from a remote station,
Since the L information is sent and received, there is no need to analyze the information in the part corresponding to the line control of the remote station, so the above-mentioned drawbacks are eliminated.
しかしながら、上記特公昭５８−５７９５５号公報に記
載されたシステムにおいては、親局からの強制的なＩＰ
Ｌができないという欠点がある。However, in the system described in the above-mentioned Japanese Patent Publication No. 58-57955, the IP address is forced from the master station.
It has the disadvantage of not being able to do L.

テムに設けるようにしたものである。In order to eliminate such drawbacks, the present invention provides an information communication line control section connected to an information communication line for carrying out a normal information communication line, and an initial program load connected to the control communication line from a master station to a remote station. The system is provided with a control communication line controller for giving instructions and for the master station to know the status of the remote station.

知るための制御通信回線制御部である。An embodiment of an initial program loading system for a remote station according to the present invention is shown in the figure. In the figure, ■ is the main processor, 2 is the main memory, 3 is an information communication line control unit connected to the information communication line 4 and performs normal information communication control, and 5 is connected to the control communication line 6 and is remote from the master station. This is a control communication line controller for instructing the station to load an initial program and for the master station to know the status of the remote station.

る。The programs of the remote station, including the program for performing information communication control procedures, should be stored in the main memory 2, and the main processor 1 operates according to the programs in the main memory 2. A normal information communication control procedure is performed by the main processor 1 controlling the information communication line control section 3, that is, the direct memory access control circuit 31 and the signal transmitter/receiver 32 based on the program in the main memory 2.

Ｌを行なうことができるようにしたものである。When no program is loaded into the main memory 2, the main processor 1 cannot control the information communication line control section 3. Therefore, in this embodiment, a control communication line controller 5 is provided, which is connected to a master station via a control communication line 6, and the master station sends the same signal as the command issued by the main processor 1 to the control communication line controller 5 to control the information communication line. 3, the master station can control the information communication line control unit 3 of the remote station and transmit the IP information via the information communication line 4.
This makes it possible to perform L.

なる効果がある。As explained above, in the present invention, the initial program load instruction from the master station is sent from the control communication line to the information communication line control unit via the control communication line control unit, and the initial program load information is received using normal information. By performing this from the communication line via the information communication line control unit, the initial program load of the remote station can be forced from the master station, and the initial program load of the information communication control program can also be performed. This has the effect of making it possible to deal with future changes.
