Teleservice via telephone - Ethernet gateway
With teleservice via telephone with Ethernet gateway, a connection via
telephone (PPP connection) is directly established from your PC to the
TM-E module. Here the CPU is linked to the TM-E module by Ethernet.
To be able to react to the calling, to authenticate the user and to assign the
IP address, the TM-E module is to be configured as PPP server.
The following picture shows the network topology on an example:
10.0.1.9
10.0.1.10
10.0.0.89
202.0.0.1
PPP connection
202.0.0.240

In the configuration above there are 3 various networks:
•
10.0.0.0 is the network of your PC.
•
202.0.0.0 is the temporary network, which is to be used for the PPP
connection. This network is only active during PPP connection.
•
10.0.1.0 is the network, over which the PLC is to be accessed.
Here the following routing configuration is to be established:
•
Configure the PC so that every IP package, based on the PPP
connection, is transferred to the 10.0.1.0 network of the PLC.
•
Configure the TM-E module so that every IP package, which was
received from address 202.0.0.240, is transferred to the address
10.0.1.0.
•
Configure the PLC so that it may answer every net except the net with
10.0.1.0.
