Abstract: According to an aspect of the present invention, there is provided a parallel fieldbus network-based motor control system including: one or more slave modules that control one or more motors and correspond to each of the one or more motors; and a master module that generates command data for controlling each of the one or more motors and transmits the generated command data to each of the one or more slave modules, wherein each of the one or more slave modules includes a basic processor and an auxiliary processor, the auxiliary processor acquires the command data from the master module via a basic network, and supports the acquired command data to be stored in a shared memory and transmitted to the basic processor or transmits the acquired command data to the basic processor via a local network, the basic processor controls the motor corresponding to the corresponding slave module in accordance with the command data acquired from the master module via the basic network, read from the shared memory, or transmitted via the local network or supports to control the motor, and supports result data executed in accordance with the command data to be stored in the shared memory and transmitted to the auxiliary processor or transmits the result data to the auxiliary processor via the local network, and when abnormality occurs in the basic network, the maser module provides the command data to the basic processor or the auxiliary processor via an auxiliary network or a wireless network, and the auxiliary processor provides the result data to the master module via the auxiliary network or the wireless network, or acquires command data for continuing to control the motor corresponding to the corresponding slave mode from the master module and supports the acquired command data to be stored in the shared memory and transmitted to the basic processor or transmits the acquired command data to the basic processor via the local network.
