Abstract

PURPOSE:To enable to reduce the data renewal time with less waiting time, by the sequential reception in the order of arrival to the master station for the transmission data from the slave stations. CONSTITUTION:In the remote monitor unit of cyclic type, it is general to throw away the data of one cycle at least, then the master station determines the order of slave station data fetch after the application of power supply of slave station, by using the idle time of one cycle after the application of power supply at the master station, and data fetch is made according to the order from the second cycle. That is, at the end of one cycle after the application of power supply by the master station, the result of counting according to the order of reception is stored in the memories 21 and 22, the word counter 27 starts the operation at the second cycle, and the received information from the MODEM's 1 and 2 is fed to the S-P converter 25 via the gate 18 with the arrangement of various conditions, into parallel information. Succeedingly, when the processing is elapsed by one cycle, the processing at the third cycle is entered. The processing can be decreased than conventional methods.
