  • Page 170: Ftp Server

    14. FtP SErVEr the controllers with Ethernet interface have built-in FtP file exchange protocol. the controller works as a server, allowing the clients to access the file system on the Sd card inserted in the controller. Access to the files is possible using a computer, a tablet with installed FtP client or other device ac- ting as a FtP client.
  • Page 171 the program FileZilla could be an example of the FtP client (Fig. 29). You can view and download the archive files by entering the IP address of the controller in the address field. Fig. 29. View of the FTP session in the program FileZilla...

    WEB SErVEr Access to the Web server is achieved by entering the meter IP address in the web browser, e.g .: http://192.168.1.030 (where 192.168.1.030 is the set address of the meter). the stan- dard port for web server is port „80”. Server port may be chan- ged by the user.
