Technical Manual for Master Terminals of the Series IF 152x
Page 28
Configuration of Network Interfaces
The master terminal requires the following data for building up TCP/ IP connections:
• Internet address (default factory setting 172.18.70.52).
• Port number (default factory setting 2001)
• Subnet mask
• Routing to host system
The data is partly given by the network administrator and must be saved in the Flash-PROM of the
MPU by means of a configuration menu during initial operation.
Internet address (default setting: 172.18.70.52)
The default Internet address is automatically restored after a cold reboot if the cold reboot switch of
the terminal is replaced in the original position within 8 seconds.
Port number* (default setting: 2001)
Port numbers are used to distinguish between data blocks, which belong to different connections and
address different processes. The combination of the Internet address and the port number is called
"socket". The socket is used for the unique identification of the connection.
Subnet mask
The subnet mask is used to determine which part of the IP address is to be the network address and
which part is to be the host address.
Routing
A routing entry is required if the master terminal and the host system are operated in different
networks or via subnets. The IP address of the gateway via which the master terminal is to send data
as well as the number of gateways to the target host are always required.
$ Points to Note:
• Except for the port number*, all the data is given by the network provider. Please ask for this data
prior to installation. The configuration can then – in advance - be carried out at your branch office.
• Do not forget to save the changed values.
• Reset the master terminal after changes have been made by pressing the reset button or via the
menu $ oc -s
. The new parameters are active after the reset has been carried out.
* The port number is normally given by the IF central system. This number can be found in the respective IF system manual.
** Ethernet node numbers are uniquely defined all over the world. The number $0020acXXXXXX is assigned to Interflex. The
last 6 digits (XXXXXX) are used for the consecutive numbering of the IF Ethernet boards.
