摘要： PURPOSE:To operate even memories having different data normally by providing the inside of a maintenance controller with an exchangeable RAM card, a RAM-card presence discriminator, a means writing pages to the RAM card by the result of discrimination and deciding the number of the pages of the RAM card and a RAM-card usage determination means. CONSTITUTION:A micro-computer 8 is provided with a RAM-card mounting presence discriminating means 23, a RAM-cad page-number decision means 24 and a RAM-card usage determination means 25. When the exchange of the RAM-card mounting presence discriminating means 23 by a RAM card is detected and the abnormality of the RAM card is detected, the RAM-card page-number decision means 24 writes pages in the page writing area of the RAM card 13 on the basis of the initial value of the RAM card 13, and decides the number of pages of the card. Consequently, the RAM-card usage determination means 24 determines the usage of the card. Accordingly, data usage is detected easily even in memories having different data and the memories are operated normally.

摘要： PURPOSE:To test the master station of a remote supervisory and controlling equipment by mutually connecting the line interface circuits of A and B both systems of a doubling constitution and when the master station or one side system is tested, operating the system of the other side in making it into a slave station simulator. CONSTITUTION:When an input, that the simulation of a second slave station is executed, is executed by the keyboard of a display 112, it is transmitted through a control circuit 122, a switching circuit 13 and a serial interface 5B4 to a main memory 2B by the control of a CPU 1B. According to a polling signal from a line interface 6A2 of the A system, the input is transmitted from a line interface 6B2 to the 6A2. The circuit 6A2 generates an interrupting signal to a CPU 1 at the time of a receiving completion, the CPU 1A rends the reception information ot the circuit 6A2, it is accumulated in a main memory 2A, it is outputted through circuits 5A1-5A3 to a system displaying panel 7, a printer 9 and a display 111, and while the a system executes the simulation of the second slave station, the A system of the master station can be tested. At the time of the test or the H system of the master station, the test can be executed in the same way by switching the switching circuit 13, and the test can be executed by only the master station.

摘要： PURPOSE:To improve the transmission efficiency of an information transmitting device utilizing a poling system, by installing a poling table which stores the poling performing order to all suboffices. CONSTITUTION:A poling table T1 which is commonly used to all communication circuits is installed and each communication circuit is numbered, and then, a poling performing order is circularly determined in accordance with the number. A communication circuit of the next order to another communication circuit performing poling at present performs poling to the next order suboffice in the poling table T1. Moreover, it is arranged that the poling table can be rewritten freely at the main office.
摘要翻译：目的：为了提高利用极化系统的信息发送设备的传输效率，通过将所有子服务器上存储极化执行顺序的极化表安装在一起。构成：安装通常用于所有通信电路的极化台T1，并且对每个通信电路进行编号，然后根据该数量循环确定极化执行顺序。当前执行极化的另一通信电路的下一个命令的通信电路对极化台T1中的下一个命令子帧进行极化。此外，安排在主办公室可以自由地重写极化桌。
