6.4 Remote maintenance via modem

Siemens offers a TS ada pter which can be used for remote maintenance. This adapter is connected

between the MPI connection of the PLC a nd 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.
