US 11,886,170 B2 · Control system, setting device and setting program

Abstract

A control system includes a control device, one or more information processing devices, and an arithmetic unit. The control device executes a control program controlling a control target while managing process data of the control program, and includes a communication processor that periodically transmits one or more data sets, each data set including a value of one or more process data. The information processing devices executes one or more applications using the process data included in the data sets. The arithmetic unit determines a transmission setting of the data set, and includes an acquirer that acquires the process data for each application, and a determiner that determines a number of data sets transmitted by the communication processor and the process data to be included in each data set according to an evaluation criterion regarding a communication load based on the process data for each application.
