Provided is a monitoring and control system which, by displaying memo information created by an operator on an arbitrary system screen, can enhance freedom of memo display and fully exhibit the effectiveness of memo information. A memo data operation portionreceives an input of memo information from an input device, imparts attribute information relating to an arbitrary system screen to the memo information, and outputs this with the memo information to a client-side data management portion. A display devicedisplays the memo information on a system screen having attribute information.

Monitoring and control system

According to one embodiment, a serverperforms aggregate signal processing for n-to-one signal transmission. The processing includes waiting processing and time adjusting processing. In the waiting processing, from a time point where a first constitutional element signal constituting a specific aggregate signal bound for the upper level control center reaches the server until a wait time that is based on a preset condition elapses, the server waits for another constitutional element signal of the specific aggregate signal to arrive (S-S). In the time adjusting processing, the server extracts an earliest generation time from generation times attached respectively to constitutional element signals arriving during the waiting processing, and attaches the extracted time as a generation time of the specific aggregate signal (S).
