PURPOSE:To facilitate the reconfirmation of message contents and secure operator's support in plant supervising operation by providing a means which outputs a speech message repeatedly by as many times as preset. CONSTITUTION:A plant computer 5 fetches a pressure, a temperature value, and an abnormal state signal, etc., from a plant 6 and performs necessary processing to retrieve a speech message number in a memory when speech message output is requested, thereby outputting it from a speaker 4. In this case the computer 5 checks the frequency of repetition of a repetition frequency setting board 7 to output the message from the speaker 4 only once when the switch of the setting board 7 is off or when the frequency is set to 1, and three times repeatedly when the frequency is set to 3. |
