Abstract
A motion controller is provided which improves system responsiveness without having to raise the arithmetic capacity of a master controller or to boost the communication speed of a network. The master controlleruses a program analysis unitto separate, from a control program designating a tolerable delay time for operating control target apparatuses, a slave use program to be executed by a slave controller in a manner not to exceed the tolerable delay time, and to create slave-to-slave communication setting information needed by the slave controller to execute the slave use program. Through slave-to-slave communication, the slave controlleracquires input/output information from another slave controller. The slave controlleralso uses a slave use program execution unitto execute its own slave use program.
