LOGIC SIMULATOR OF PROCESS CONTROL SYSTEM FOR OFFSHORE PLNAT

摘要

PURPOSE: A logic simulator of a process control system for a marine plant is provided to perform a test in all over the system through a simulator through a simulation, thereby preventing an operation accident, caused by a change of a process control logic, in advance. CONSTITUTION: A logic forming unit(10) forms a process control logic to simulate according to resources and supplies a simulation mode to simulate the process control logic. A virtual PCU(Process Control Unit)(20) performs the process control logic and outputs a value. A virtual I/O(Input/Output) device(30) interfaces the virtual PCU with I/O data of a resource unit and virtually configures I/O.
