Establishing a modem connection via the general telephone network
Set up the network via the modem terminals as follows (please also refer to the figure below):
1. Connect the PC with the general telephone network via the modem terminal.
2. Connect the TS adapter with the general telephone network via the modem terminal.
3. Connect the TS adapter with the control system's X127 interface via the Ethernet interface.
Use an Ethernet cable for this purpose.
There is no need to integrate the TS adapter into the system network/workplace network,
as the control system operates its own DHCP server on the X127 interface.
The TS adapter is automatically assigned an IP address from this X127 interface.
Note
The control system is still accessible via the X130 interface, for example.
