摘要:
The reliability of output data is enhanced, and the frequency of stopping arithmetic devices is reduced. A redundant system includes an input device; a plurality of arithmetic devices that receive input data from the input device; and an output device that receives output data output from the arithmetic devices, the redundant system causing the arithmetic devices to perform the same processing. Each of the arithmetic devices includes: a first communication unit that acquires the input data from the input device; and a second communication unit that sends the input data acquired by the first communication unit to other arithmetic device and receives the input data acquired by the other arithmetic device from the other arithmetic device.
摘要:
A Plant safety design assistance device (100) is configured by a communication device (140), a diagnostics and monitoring device (110), a fault inspection management device (120), and a design and manufacturing device (130) being interconnected via network (150). The diagnostics and monitoring device (110) receives plant status information (dc) from a plant control system (1) and carries out monitoring and diagnostics an the plant. The fault inspection management device (120) maintains fault inspection information (D2) of an apparatus which is used in the plant. The design and manufacturing device (130) maintains design and manufacturing information of the apparatus which is used in the plant. The design and manufacturing devise (130) receives the fault inspection information (D2) from the fault inspection management device (120), and carries out a plant safety design which takes the fault inspection information into account. The plant safety design is thus assisted, with the plant monitoring and maintenance activities being linked therewith.
