Abstract

PURPOSE:To recording effectively process values of plant data at an anomaly occurrence time to simplify to clear up the cause, by recording plant data change while changing the recoring period according to the change state. CONSTITUTION:Plant data Pi from object plant 1 is taken into digital computer 3 through process input device 2 and is stored as follows; the digital computer is started by a timer periodically to write endlessly data from the current time to time MO into a table just before anomaly occurrence. Data before time MO is written into another table at the period corresponding to state change. When anomaly signal Aj of anomaly signal output circuit 6 exists, data is recorded into the table just after anomaly occurrence only for time NO, and after time NO, data is written into another table at the period corresponding to change.
