6.4 Remote maintenance via modem
Siemens offers a TS adapter which can be used for remote maintenance. This adapter is connected
between the MPI connection of the PLC and a commercial modem. The programming device which is
also equipped with a modem can now communicate with the PLC via a standard telephone connection.
Instead of using the programming device to carry out the remote maintenance, you can also use the
bus server installed at a PC equipped with a modem.

In addition to the TS adapter for the PLC, the following software components are required for the PC
to carry out remote maintenance via a modem:
• Siemens TeleService software
• Siemens STEP7
Tip!
• The connection with the remote maintenance system always has to be established manually.
• The bus server may only be started after the connection has been established, otherwise
communication is not possible.
