Abstract
The present disclosure relates to a synchronization control device and method of slave devices connected to a network capable of synchronizing operations of the slave devices, wherein a communication module generates a first synchronization signal and a second synchronization signal according to a distributed clock function, generating, by a processor, a control data for driving an actuator according to the first synchronization signal, outputting to a driver the control data if a synchronization interrupt is generated by the first synchronization signal, and inputting and processing, by the processor, a reception data of the communication module to generate the control data, and generating a timer interrupt on a period set up by a timer according to control of the processor, and generating, by the processor, the control data to output the generated control data to the driver if the first synchronization signal is not generated but the timer interrupt is generated.
