PURPOSE:To make an event message string time-series in real time, by providing a queue, where event messages with detection times added are registered, in each lower-level computer and comparing detection times of the first events of these queues to read out them by a host computer. CONSTITUTION:The transmission format of an event message transmitted from a subordinate computer is constituted with communication control information 7, an oscillation source equipment code 8, an event detection time 9, an event identification code 10, additional information 11, etc. The host computer distributes and registers a received event message string 12 into queues 13 for respective subordinate computers. First data of queues 13 for respective subordinate computers are read out in the order of detection time while comparing detection times between subordinate equipments. By the successive execution of this processing, the string 12 of event messages arranged in order of receipt is rearranged into a time series event message string 16. |
