Abstract

PURPOSE: To enahnce the efficiency of the system running and the reliability thereof by filing the file of μCM also in the upper-rank computer too in the system composed of the upper-rank computer and plural function divergent type microcomputer μCM.
CONSTITUTION: The process control system comprises a central process computer 1, a remote computers 8, 9 of the divergent subsystems A, B, and μCM10, 11 for carrying out the control or the data collection of the object processes 12, 13. μCM10 process of the system A scans in a predetermined cycle with respect to the process 12, and renews the file 10. At the same time as the completion of the scanning, the data parameter is transmitted to the computer 8, and from the slave station 6, transmitted to the upper-rank computer 1 through the data transmission line 5 and the master station 4. In the central portion, in the file C of the bulk memory 2, the newest information at the side of the process can be provided, and when μCM10 is down, in accordance with the cause condition, the newest information of the file C can be employed. Similarly to the system B, the data of the file E is accommodated in the file C.
