INTEGRATED SYSTEM, SYSTEM INTEGRATION METHOD, AND PROGRAM FOR SYSTEM INTEGRATION

摘要

PROBLEM TO BE SOLVED: To provide an integrated system, a system integration method, and a program for executing the system integration method that can integrate two systems, while maintaining similar convenience as when individual system is used.;SOLUTION: A safety controller has a function block and a mapping block. The function block executes intrinsic functions to the safety controller. The mapping block converts data used in a control system among data handled by the function block into a data format that is handleable directly by the control system, and assigns a common tag to the data. The mapping block executes computation according to the data handled by the function block, and outputs a signal to specify whether to transmit a process alarm according to the computation result. The common tag is also assigned to the signal. As a result, the control system can recognize that the data groups are mutually related.;COPYRIGHT: (C)2006,JPO&NCIPI
