FTP Client
The CX can connect to an FTP server on the network as a client and automatically
transfer data files that are stored in the internal memory of the CX. You can specify two
destination FTP servers, primary and secondary. By setting the secondary FTP server,
the data file can automatically be transferred to the secondary FTP server even if the
primary FTP server is down.
Below are the data files that can be transferred.
• Display data file
• Event data file
• Report data file
The result of the data transfer to the FTP server is recorded in the FTP log. You can
confirm the FTP log on the CX display or from your PC connected to the CX.
