PRINTING PROCESSOR

PURPOSE:To prevent print output loss of fault information due to a print output buffer overflow and then to offer fault data which are high in importance to an operator of a control station without any loss while securing its instantaneous ness and time-series property. CONSTITUTION:If multiple faults occurs successively, a print output buffer overflow detection part 6 compares the value of the number of pieced of fault information stored in a print output buffer with the value of transmission buffer overflow decision data 7 and when the former value is larger than the latter value, an editing process part 11 loads an intensive editing data base 8 and intensively edits >=2 pieces of fault information into >=1 print output data. Consequently, the information required for operator's operation can accurately be printed out.
