CHAPTER 10: FTP SERVER PROTOCOL
10.1 FTP Overview
File Transfer Protocol (FTP) is a standard Client/Server Internet protocol, based on RFC959,
which supports efficient and reliable file transfers over a TCP/IP network. In this context, the
Ethernet Module acts as an FTP Server, which responds to file transfer requests from one or
more FTP Clients.
Note: As indicated in Table 1.2 (page
7 ), FTP protocol is supported only by OCS Models, which
have built-in Ethernet and an OCS file system with removable media (such as Compact
Flash / Micro SD). For OCS Models that do not have an OCS file system, the FTP (File
Transfer) checkbox will be grayed out in Cscape’s Ethernet Module Configuration dialog.
The Ethernet Module’s FTP Server supports both anonymous and authenticated file transfers
between an FTP Client and the OCS file system. Authenticated file transfers require that the FTP
Client provide one of two possible User Name and Password pairs, before the OCS file system
can be accessed.
Properly authenticated, an FTP Client can access OCS file system functions, which include file
read, file create, file delete, file rename, file write, directory read, directory create and directory
delete.
10.2 FTP Configuration
If FTP File Transfer will be used in the application, FTP Configuration must be performed, in
addition to the general Ethernet Module Configuration previously described in Chapter 3. To
configure FTP protocol, use Cscape Programming Software to perform the following five steps:
1. Open the Ethernet Module Configuration dialog (Figure 3.5 [page 18]), as described in
Chapter 3.
2. Enable FTP by checking the FTP (File Transfer) checkbox in the Ethernet Module
Configuration dialog (Figure 3.5). Until this is done, the OCS will not respond to any FTP
Client requests.
3. Click on the Config button next to the FTP (File Transfer) checkbox to open the FTP
Configuration dialog (Figure 10.1).
