A method for configuring an industrial control apparatus, the method including: starting a detection mode; selecting a stock control apparatus; opening a stock configuration of the stock control apparatus; selecting and buffer-storing at least one feature of the stock configuration; starting a transfer mode; selecting at least one target control apparatus; and transferring the at least one selected and buffer-stored feature of the stock configuration to the target control apparatus.

A communication system include: a first communication device configured to: add order information to each of the plurality of data sets; and sequentially transmit the plurality of data sets to which the order information is added; and a second communication device configured to: receive the plurality of data sets from the first communication device; arrange the plurality of received data sets in a standby buffer as ordered data sets based on the order information; and sequentially read the ordered data sets.

There is provided a method for saving fault wave data, in which when a fault wave generated in a system is saved, a size of wave data is calculated, and the saving of the wave data is performed according to the size of the wave data, so that it is possible to implement the use of spaces of a buffer and a memory and the simultaneous saving of wave data simultaneously or subsequently generated. Accordingly, it is possible to minimize a delay in the saving of the wave data. Also, it is possible to record all accurate wave data even when consecutive faults occur. Also, it is possible to efficiently use the space of the memory.
