PURPOSE:To attain a load reduction of a computer side, by coupling a computer and a remote monitoring and controlling device by use of one kind of computer linkage device, and sending a data which has been processed by the remote monitoring and controlling device, to the computer. CONSTITUTION:In a system which has coupled a computer 1 and a remote monitoring and controlling device (super-master station) 2, as for the information sent from each slave station, necessary information in said information is displayed on a display panel 4 through a MODEM 26 and an S-P converter 27, is stored in the memory of an operation processing part 29 through an display information receiving part 28, and processing such as detection of status change, scale conversion, etc., and display onto an operation display desk 3 are executed. A data processed by the operation processing part 29 is transmitted to the memory in a CPU11 of the computer 1 through computer linkage devices 14, 31 by a described format at every constant period at all times. Au automatic control signal from the computer 1 is also transmitted to the memory of the operation processing part 29 by a prescribed format through the linkage devices 14, 31, and is transmitted to each slave station through a transmission part 32 and a P-S converter 33. |
