SSW7-TS, MPI-Adapter mit Teleservice-Funktion

MPI Adapter with teleservice function

The SSW7-TS can be used for remote maintenance of your system over a modem connection. To this purpose, a commercially available external modem (analog, ISDN, GSM) is connected to the RS232 interface of the SSW7-TS. 
For local use, just connect the RS232 interface of the SSW7-TS to your PC. It automatically recognizes the baud rate used by the PC (9.6 to 115.2 kBaud). 
On the system side, you can connect the SSW7-TS to an MPI network with 187.5 or 19.2 kbps.
On the PC, the programming software and teleservice software are required (such as teleservice for Simatic* STEP* 7) to parameterize the SSW7-TS when needed or to manage the modem connections. Without modem and teleservice software, the SSW7-TS can be used locally as a SSW7. 
The SSW7->TS is supplied with voltage by the MPI bus of the CPU and can be deployed at any location in the system using an optional 24 V connection.
It is also possible to load the SSW7-TS with new firmware using a modem connection, which makes it possible to realize a functional expansion of an adapter already installed in the system. 
Parameterization and diagnostic functions are possible using the SHTools software. 
For a firmware update, the latest SHTools version is available for free download on our website
