CONTROL DEVICE AND CONTROL METHOD CAPABLE OF EXTERNAL SYNCHRONIZATION

摘要

There is provided a control device capable of executing control processing by synchronizing with a synchronization signal from an upper node device without considering the difference between the clock generating the synchronization signal of the upper node device and the clock generating a control cycle signal of the control device and capable of improving the control accuracy. In the control device including a control interrupt processing section, a synchronization interrupt processing section adjusts means for generating a control cycle signal and generates a control interrupt signal so that the control cycle signal is generated with a delay equal to or greater than an accuracy error between the crystal oscillator for generating the synchronization interrupt signal and the crystal oscillator for generating the control cycle signal. Thus, it is possible to execute the control interrupt processing synchronized with a synchronization signal from outside.
