Web Server – WS10
NOVUS AUTOMATION 6/33
WS10 CONFIGURATION
Installing and configuring the WS10 require networking expertise. Consult your company’s network administrator.
GENERAL INFORMATION
The WS10 configuration is accomplished through the Ethernet interface making use of ordinary network programs: FTP (File Transfer Protocol – for
transferring files to/from the WS10) and Telnet (to access the configuration console). The FTP is normally provided with the Internet navigators
(Internet Explorer or Netscape); other FTP programs can also be used. The Telnet application is available in the operating system of your
computer, although other Telnet client applications can be used.
In order to configure the WS10, it must be powered and connected to the Ethernet though a hub or switch, or directly to the Ethernet interface of a
computer (in this case a cross cable must be used). The WS10 IP address must be known to get FTP or Telnet access to the WS10.
The WS10 factory settings are:
IP = 192.168.200.200
NetMask = 255.255.255.0
Gateway = 192.168.200.1
DHCP disabled
The computer used to access the WS10 must be on the same sub-network of the WS10. To access the WS10 with the factory settings, the IP
addressing configuration of the computer must be:
IP = 192.168.200.xxx (where xxx can be any value except 200, already assigned to the WS10)
NetMask = 255.255.255.0
TELNET CONFIGURATION
To change IP configurations, it is necessary to establish a Telnet connection with the WS10 to get access to configuration console. Run your
preferred Telnet application and connect your computer to the WS10 IP address, using the Telnet standard port. When the WS10 is found, the
message “Novus WS10 Telnet Session” is presented. The WS10 prompts for Username and password. The factory values are:
Username: telnet
Password: telnet
Once connected, the message “User logged in” is showed indicating the connection success. With the Telnet application running, the WS10 gives
access to commands similar to the ones of the DOS operating system. The commands are executed when the Enter key is pressed
Through the Telnet console, a user can modify important configurations in the WS10. Only capable users should use this
feature. Use only the commands listed on this section.
The following commands are related to the configuration of the WS10 IP address and may be needed in the configuration process.
IPCFG: Shows current IP address.
IP aaa.bbb.ccc.ddd: Defines a new IP address for the WS10.
NETMASK aaa.bbb.ccc.ddd: Defines a new subnet mask for the WS10.
GATEWAY aaa.bbb.ccc.ddd: Defines the gateway address.
DHCP n: n = 0 disables the dynamic addressing through DHCP; n = 1 enables dynamic addressing.
REBOOT: forces the WS10 reboot. A new IP address is effective only after the reboot. Following the reboot, the Telnet connection is lost. To
re-establish the connection, use the new IP address. In the case of the new IP address falls in another subnet, it will be necessary to change
the address of the computer used in the configuration to this same subnet.
WS10 –v: Shows the Web Server software version.
The same console commands may be available on the SERIAL 2 communication port, provided it is RS232 and is not being used as a PPP client
or Server. Factory settings for the communication parameters are: Baud Rate 19200 bps, no parity, 8 bits, 1 stop bit. Use a RS232 cable and PC
serial communication program to communicate over this port. This feature may be factory disabled depending on the WS10 version and hardware
options.
FILE TRANSFER USING FTP
The configuration of the WS10 is defined by text files stored in its memory. These files can be transferred to a computer, modified, and copied back
into the WS10. The new configurations will be effective when the WS10 is rebooted. The WS10 incorporates a FTP Server compatible to the
majority of the FTP clients available, like the ones provided with the navigators Internet Explorer and Netscape. The Windows Explorer can also be
used for this purpose.
To establish a FTP connection with the WS10, write the WS10 IP address in the navigator address bar, as shown below:
If prompted, inform username and password. The FTP factory settings are:
Username: ftp
Password: ftp
The WS10 factory settings allow anonymous FTP connection also.
The WS10 internal files and directories are shown. It is possible to drag the files and directories from the WS10 to any other local directory or
network location, and the other way around.
Configuration files that require modification can be copied to a computer temporary directory, edited, saved and stored back in the WS10. The
modifications performed on the configuration files will become effective in the next boot.
In some navigators, the FTP access may refuse connection even with the correct password. The way around is to inform username and password
along with the IP address. The example below illustrates this procedure for username user and password pass:
ftp://user:[email protected]
