I have many PLCs (Programmable Logic Controller) throughout the world that are used in an industrial plant to gather historical data (temps, pressure, quantity, ON/OFF state of equipment etc). This data is then sent as a .csv text file via FTP to a server when the local user pushes a button on the control panel. I created a user account for the PLC to send files to. I can use the FTP client within WinXP to access the new user account. My problem is I can’t get my PLC to send its file to the DreamHost servers. I can set up a simple FTP server on a local PC and the PLC will send its file just fine.
Is there some simple thing I missed that is preventing the FTP server from receiving the file?
