摘要： A most recent value of data fetched from a plant facility is temporarily stored and extracted and then stored in a plant history data table. On another front, a monitoring point for monitoring a plant error is registered in response to an operator request. A monitoring point is used as a key to select and register a main variable point having a strong correlation from the plant history data table. A statistical upper/lower limit function is defined on the basis of time-series plant data of monitoring points and main variable points. By referring to information in a table in which a limit value function is stored, the limit value is periodically matched with the content of a plant-data most-recent-value table. If the most recent value is outside the limit range, deviation information is stored in a determination result table. If a new plant error occurs, an error signal and the content of the determination result table is outputted and displayed.

摘要： To provide a plant operation data monitoring apparatus capable of monitoring a plant error with high accuracy without requiring a skilled plant operator.A most recent value of data fetched from each sensor in a plant facility is temporarily stored and extracted and then stored in a plant history data table A5. On another front, a monitoring point for monitoring a plant error is registered in response to an operator request. A monitoring point is used as a key to select and register a main variable point having a strong correlation from the plant history data table. A statistical upper/lower limit function is defined on the basis of time-series plant data of monitoring points and main variable points. By referring to information in a table in which a limit value function is stored, the limit value is periodically matched with the content of a plant-data most-recent-value table A3. If the most recent value is outside the limit range, deviation information is stored in a determination result table A13. If a new plant error occurs, an error signal and the content of the determination result table is outputted and displayed.

摘要： The present invention relates to holding a call being executed between communication devices in a communication system which has a first function for a holding party of the communication devices to hold the call by transmitting a first request signal to a held party and a second function for the holding party to hold the call by transmitting a second request signal to the held party and receiving a response signal. The holding party transmits the second request signal first and when the response signal is not returned within a given time, transmits the first request signal. A transit device for relaying a call between communication devices, unless detecting the response signal within a given time after relaying the second request signal, transmits the first request signal to the held party, generates the response signal and transmits the generated response signal to the holding party.
