A control device includes: an input portion for inputting a process signal transmitted from a plant; a numerical processing part for outputting a Boolean value evaluating normal/abnormal of the process signal by a numerical processing based on a program; and a logical processing part for a logical processing of the Boolean value based on a logic circuit and then outputting a control signal related a safety protection operation of the plant.
摘要:
In a digital control device, when a normal mode for carrying out a normal process is selected by a mode switch, a computation unit transfers base process code and APL process code which controls the normal process from a code storage device to a main memory, loads the base process code and the APL process code which are transferred to the main memory, and carries out the normal process. When a test mode for carrying out a test process is selected by the mode switch, the computation unit transfers the base process code and test process code which controls the test process from the code storage device to the main memory, loads the base process code and the test process code which are transferred to the main memory, and carries out the test process.

A verification method is provided for verifying a safety apparatus including a programmable logic device having a plurality of functional elements. The verification method includes the steps of exhaustively verifying the plurality of functional elements on actual hardware, generating a functional element that is the same as one of the functional elements verified on the actual apparatus using a predetermined hardware description language, independently logic-synthesizing each generated functional element into a plurality of first net lists, generating a connection function between the functional elements using the predetermined hardware description language, logic-synthesizing the generated connection function into a second net list corresponding to the connection function, synthesizing the first net lists with the second net list to generate a third net list, writing a logic circuit into the programmable logic device on the basis of the third net list, and verifying the actual programmable logic device.
