SCHEDULING DEVICE FOR FIELD BUS SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide the scheduling device of a field bus system for correctly operating a control system in which function blocks in different field equipment are connected. ;SOLUTION: A timing for allowing a function block to execute a processing or the function blocks to mutually execute communication is decided for each function block (1). Processing scheduling data are constituted of the data system of the processing starting time, identification name, and maximum processing time of the function block, and communication scheduling data are constituted of the data of the communication starting time, identification name of the origin of transmission, identification name of the designation of transmission, and time required for communication (2). This device is provided with a generation means 205 which converts the generated scheduling data into data in a data format to be processed by a field equipment (3).;COPYRIGHT: (C)1998,JPO
