Chapter 6 Deployment CPU 31x with TCP/IP Manual VIPA System 300V
6-16 HB130E - CPU - Rev. 11/50
Date, Version The entry of date and version serves your own documentation. It always
shows the last parameterization alteration.
Station name You may assign a name for the station (max. 19 characters). Station
names serve the overview and eases the parameterization of
connections. Please take care with the symbolic addresses that the
symbolic name of a station res. its address and the station name of the
parameterization here are identical.
This allows a stringent name assignment.
Page frame
basic address
CP is fixed to a page frame basic address of 0.
Page frame number CP is fixed to a page frame number of 1.
Station address CP is fixed to Ethernet address (station address) 000000000000.
IP address The IP address is a 32Bit address that must be unique within the network.
The address is a combination of 4 numbers separated by a dot.
To build-up private IP networks within the internet, RFC 1597/1918
reserves the following address ranges:
Class A: 10.0.0.0 ... 10.255.255.255
Class B: 172.16.0.0 ... 172.31.255.255
Class C: 192.168.0.0 ... 192.168.255.255
At first start-up the following address and subnet mask is preset in the CP
part:
IP address: 172.16.192.11
Subnet mask: 255.255.255.0
Subnet mask The IP subnet mask is a 32Bit filter mask for IP addresses. Deploying
subnet masks, subnets are build-up by definition of IP number circles.
Subnets only communicate with each other via router.
The address entered here has the same structure and value range like
the IP address. For the project engineering of a CP with the PC, you have
to make sure that PC and CP have the same subnet mask.
Router A router is able to connect different network topologies with each other
like e.g. Ethernet with token ring. It also serves the connection of subnets.
Router have one IP address per network that connect the networks
logical. A connection of 2 networks via router has 2 addresses.
If you don’t want to use router IP addresses you enter 0.0.0.0 at router.
