摘要： An EtherCAT control device and a factory automation system having the same are provided. The EtherCAT control device includes a master including a dummy EtherCAT slave controller (ESC) and a first slave configured to communicate data with the master according to an EtherCAT protocol, such that the master synchronizes a timing with the first slave according to a precision time protocol (PTP) method using the dummy ESC.

摘要： A method for determining a position of a fault of equipment includes receiving a plurality of sound source signals from a plurality of sound source inputting apparatuses, determining an abnormal operation of the equipment by analyzing at least one sound source signal among the sound source signals, and extracting abnormal sound source signals from the sound source signals. The abnormal sound source signals are indicative of abnormal operation of the equipment. The method further includes determining a position of the abnormal operation based on a time difference between the abnormal sound source signals.
