プログラマブルロジックコントローラ
Document Type and Number:
Japanese Patent JP4818492
Kind Code:
B1
Abstract:
A PLC is enabled to determine whether device data has been completely transferred to an FTP server and is improved in the flexibility of setting for a completed-transfer notice code. To this end, the PLC includes a logging section for logging device data and outputting a log file describing the results of logging of the device data to a memory card; and a file transfer section for transferring the log file delivered to the memory card to the FTP server. After having completely transferred all the data that constitutes the log file (Yes in step S15), the file transfer section inserts the completed-transfer notice code specified by a logging setting parameter 40 predefined by the user into the log file transferred to the FTP server and stored in the FTP server (step S17).
