How does a Com-Server get its IP address?

For the Highspeed generation of Com-Servers, the following four alternatives are available for the first assignment of the IP address. Detailed outlines of all procedures are specified in the relevant section of the Com-Server Highspeed manual.

• Management and inventorying tool WuTility
  Using the Scan function of WuTility, Com-Servers and Web-IOs located in the local sub-network are automatically searched for and shown in a list. Devices whose current IP address is 0.0.0.0 (= factory default setting) can then be assigned a valid address using the button Assign IP address.
• Static ARP cache entry
  Via a static entry in the ARP cache of a TCP/IP computer located in the same sub-network followed by a ping. As also in the case of employment of WuTility, this method can only be used if the Com-Server does not yet have an IP address at this point in time.
  Input example in Windows: arp -s [IP address] [MAC address]
• Assignment via the serial interface
  If the Com-Server receives a continous data stream during boot-up (data format 9600, n, 8) with content “x” (=ASCII 120), a prompt is generated making it possible to enter a new IP address. This method overwrites and functions regardless of whether an IP address has already been assigned or not.
• Assignment via BOOTP / DHCP
  In centrally administered networks, the IP address can also be assigned using a DHCP or BOOTP server. This method also offers the advantage that these protocols can also be used for setting the subnet mask and the gateway address. In such centrally administered environments, before connecting the Com-Server please contact your system administrator and ask him to reserve a fixed IP address in the DHCP system for the Com-Server.
