Abstract

PURPOSE: To realize the labor saving for the computer maintenance by performing the reading and writing control of the main memory via the upper-rank computer for the lower-rank computer.
CONSTITUTION: Upper-rank computer system 9 memorizes the contents of main memory 5 in external memory unit 10 for process controlling computer 2 of lower- rank computer system 1. When the contents of memory 5 of computer 2 is broken down, the operator of system 9 gives the command of remote loading RL to upper computer 8 via console input/output device 11. In this case, computer 8 transmits the "special connection request" differing from the ordinary telegram to system 1 through communication control unit 7. Then communication control unit 3 of system 1 starts built-in microprocessor when receiving the "special connection request" to carry out the processes based on the subsequent orders. These processes can be carried out regardless of the dead or alive state of computer 2, thus ensuring the considerable merit in terms of the maintenance.
