摘要:
A programmable logic controller (PLC) system, and more particularly, a data processing apparatus and method in the PLC system are provided. In the data processing method in a programmable logic controller (PLC) system, first dummy code data is output to an area having a chip selection signal for valid data output. The valid data is output after the first dummy code data is output. And second dummy code data is output when the valid data output is completed.
