Abstract
PURPOSE: To make it possible to succeed smoothly to the control of a process even for anomaly of an operating computer by providing two computers for the control of the process and transmitting always data to the other queuing computer while one computer is operating.
CONSTITUTION: When a switching unit is placed in the position in the figure, process I/O device 2 is connected to computer 11. Computer 11 controls a process on a basis of data inputted from device 2 and stores cumulative data in memory unit 11' and further transmits this data to the other computer 21. Computer 21 stores receiving data in memory unit 21'. During this operation, an anomaly signal is outputted from alarm unit 14 and is inputted to interrupt input device 25 of computer 21 when computer 11 becomes abnormal. Then, device 2 is connected to computer 21 by switching switching unit 1 by computer 21 and can succeed to the process control in stead of computer 11.
