How does the Web-IO obtain the valid subnet mask and gateway address?

In order to be able to communicate beyond the local network, in addition to the IP address, the Web-IO also requires the subnet mask and gateway address applicable for the relevant sub-network. The two values must be requested from the network administrator responsible.

• Setting via Web-based management
  After the administrator logs onto the webpage of the Web-IO, all TCP/IP parameters in the area Config >> Device >> Basic settings >> Network can be entered and saved effortlessly in the corresponding fields .
• Setting via the Telnet configuration menu
  If the Web-IO already has an IP address, then the subnet mask and gateway can be assigned and saved via the Telnet configuration (telnet [IP address] 1111] from a computer located in the same sub-network.
• Assignment via the serial interface
  For Web-IOs commencing from firmware version 1.39/205, the subnet mask and gateway address can also be configured via the serial interface. During the serial IP assignment, the values can be specified separated by commas, with no separating spaces.
  Input example: 172.17.222.10,255.255.255.0, 172.17.222.1
• Assignment via BOOTP / DHCP
  In centrally administered networks, the subnet mask and the gateway can also be assigned together with the IP address via the BOOTP or DHCP server.
