摘要： PROBLEM TO BE SOLVED: To provide a controller which doesn't have input/output points of operation end drive modules fixed and can be reconfigured arbitrarily correspondingly to various auxiliary machines and to provide a plant control system using the same, which has the smaller number of wires.
SOLUTION: A PDCM (operation end drive module) 200 belonging to a controlling controller 100 is provided with a CPU 202, a non-volatile memory 203, and a serial I/F 204 and transmits and receives serial signals to and from a relevant apparatus as an object auxiliary machine through a serial signal line 300 and an RTB 400. A program of a protection function etc. peculiar to an operation end is stored in the memory 203 of the PDCM 200, and the operation end 500 is held by the CPU 202 in the case of break-down of the controller 100. In the case of abnormality of an air source 510, the operation end is operated to a fail-safe side (full open/full close). Since input/output points of the PDCM 200 are not fixed with respect to hardware, functions can be extended and changed arbitrarily.

摘要： PROBLEM TO BE SOLVED: To provide a controller capable of arbitrarily rearranging the input and output points of an operation end drive module corresponding to various auxiliary equipment without fixing them and to provide a plant controller in which the number of wiring is small.
SOLUTION: A PDCM(operation end drive module) 200 belonging to a controller 100 for control is provided with a CPU 202, a non-volatile memory 203, and a serial I/F 204, and a serial signal is transmitted and received through a serial signal line 300 and an RTB 400 with the related equipment of a target auxiliary equipment. The memory 203 of the PDCM 200 is stored with a program for a projecting function or the like specific to the operation end, and when the controller 100 breaks down, the hold of an operation end 500 is executed by the CPU 202. Also, when an air source 510 is turned to be abnormal, the operation end is operated to a fail/safe side (full open/full close). The input and output point of the PDCM 200 are not fixed like hardware so that the extension or change of the functions can be arbitrarily executed.

摘要： PROBLEM TO BE SOLVED: To improve the reliability of radio communication under a noise environment, and to realize the overall adoption of a control system to a network. SOLUTION: A transmitted data generating part 118 of a station 100 digitizes data (a control instruction) from a controller 100 into a positive waveform and the inversion waveform, and generates a communication frame to the destination of a station 102. A transmission and reception modem 111 transmits the communication frame by radio with a frequency fl, and a transmission and reception modem 112 transmits it with a frequency f2. Transmission and reception modem 131 and 132 of the station 102 at an operating terminal side receive the communication frame with each frequency f1 and f2, and store it in a reception buffer 134. An inversion check part 135 operates the parity check of data for each frequency, and judges that the data are normal when one positive waveform and the inversion waveform are completely inverted. When both of them are asymmetrical, a data reproducing part 139 puts together normal parts bit by bit, and reproduces normal data.

摘要： PROBLEM TO BE SOLVED: To quickly and exactly prepare and change control software by a plurality of maintenance tools by attaching an identifier for indicating the same function to a drawing and a program obtained from this drawing for the coincidence discrimination or mutual reference of the drawing and the program. SOLUTION: In a maintenance tool A03, a revision (an identifier such as a number) accompanying the change of control software due to the update or alteration of a plant is added to the sheet units of a drawing, and in generating an execution program from the drawing, the revision is reflected on the execution program so as to be managed. The maintenance tool A03 has the same program as an execution program A20 of a controller 02 as an execution program A19 for operating the maintenance and management of the controller, and the maintenance tool A03 is provided with a reference tool management data base(DB) 40 for managing a maintenance tool and a reference sheet which refers to a drawing DB 18 including a plurality of sheets being the dividing units of an arithmetic operation for generating the execution program.

摘要： PROBLEM TO BE SOLVED: To provide a duplex system for a controller in a process control system in order to improve the reliability, continuity and safety of the process control of the system. SOLUTION: The duplex system consists of a main controller 1 and a standby controller 2 and periodically secures the coincidence of data necessary between both controllers. Then the data necessary for coincidence between the controllers 1 and 2 are previously decided among the input/output data on the arithmetic elements 7a and 7b of the controller 1 and also the internal data used for operations of both elements 7a and 7b. When the data requiring the coincidence between both controllers are calculated by operations in every arithmetic cycle, these calculated data are written in a coincidence data area 9a of a memory 8a of the controller 12 and also transferred into a coincidence data area 9b of a memory 8b of the controller 12 in a coincidence processing cycle.

摘要： PURPOSE:To reduce a required storage quantity by compressing data while accumulating respectively in X and Y directions. CONSTITUTION:A picture in the usual state in a prescribed monitor area is inputted by an ITV camera 1 and a pre-processing circuit 3 implements pre- processing such as smoothing to eliminate noise. Then a projection distribution arithmetic operation 4 accumulates the processed picture in X and Y directions respectively to obtain the projection distribution in the X and Y directions. The result of the distribution averaged in the X and Y directions respectively is used for a reference projection distribution of the monitor area and it is stored in a reference projection distribution memory 5. A comparator discrimination circuit 8 compares a prescribed threshold value set for each object with a projection distribution in each direction and when the setting value is exceeded, it is discriminated that there is any change in the monitor area and an alarm is raised. Thus, data for each picture element are not entirely stored but the data are compressed through accumulation in the X and Y directions by one line each thereby reducing required storage data quantity.
