摘要： PURPOSE:To make it possible to monitor an operational limit value continuously. CONSTITUTION:A performance computed data input control part 15 receives, as an input, performance computed data comprising an operational limit value computed at a prescribed computation period by an electronic computer 1 for performance computation a process amount affecting variation of the operational limit value. An input control part 14 receives the process amount from a plant as an input. A correcting operation formula storage part 18 stores a correcting operation formula determined beforehand by approximation of the relationship between a minute change of the process amount and a change of the operational limit value corresponding thereto. Using the performance computed data as an initial value, an operational limit value correcting operation part 16 executes a correcting operation repeatedly at a shorter period than the aforesaid prescribed computation period on the basis of this initial value, the amount of the change of the process amount inputted from the input control part and the correcting operation formula and thereby determines a fresh operational value sequentially. An output control part 17 outputs the operational limit value outside.

摘要： PURPOSE:To decrease errors due to temperature change and to make it possible to use this apparatus in all environments by correcting an electric signal which is sent from a differential pressure transmitting device by the temperature of a heat reserving case which is obtained from an ambient temperature detector. CONSTITUTION:A differential pressure transmitting device 3 is contained in a heat reserving case 2. An ambient temperature detector 11 is provided in the vicinity of the differential pressure transmitting device 3. The obtained temperature signal is sent into an electronic computer 5 through a process input/output device 4 by the same way as a differential pressure signal. The electronic computer 5 corrects the error in the differential pressure signal from the inputted temperature signal. In this way, the flow-rate measuring apparatuses can be provided under various environments, and errors in flow rates can be decreased by the temperature correction.

摘要： PROBLEM TO BE SOLVED: To reduce the burden of a job by supporting the job. SOLUTION: A specification input device 1 successively selectively inputs a specification form a list composed of system names and function means and inputs this specification as a system request specification, and a specification input processing part 2 reads it as the request specification data due to the system request specification. A function data preserving part 5 registers a previously already constructed system and preserves the contents of function names as function data. Based on the request specification data, a function data processing part 4 extracts the function data corresponding to the function name from the function data preserving part 5 with the function name as a retrieval key. A function specification preparing part 6 prepares the function specification data by editing the extracted function data. A specification output part 7 works the function specification data into the format of prescribed specification.
