The SSW7-TS with integrated modem is a low-cost alternative for teleservicing a programmable controller via the MPI bus. 
Depending on the version, an analog, ISDN, or GSM modem is integrated in the housing of the SSW7-TS. The analog modem
can be configured for worldwide use. The ISDN variant supports the DSS1 protocol that is used in many countries. All connecting cables required for operation are included. The SSW7-TS with a GSM modem (quadband) is the right choice for mobile use or if a
telephone connection is not available.
Via the serial interface, the SSW7-TS with modem can also be used as a PC adapter for local use. The modem can be used for teleservicing a VISU/SCADA application even without a TS adapter
function. Settings are made using microswitches on the adapter housing. The SSW7-TS with modem receives its power supply from the CPU via the MPI cable. If no 24 V supply is available at the connection point, it is possible to feed in an external 24 V power
supply.
The SSW7-TS with modem can also be updated with new firmware via a modem link. That enables functional expansion of an adapter already installed in the system.
