SSW7 MPI-Programmieradapter, RS232


The SSW7 allows you to connect a PC or laptop with programming software to automation devices via every standard COM interface.

The MPI interface operates at 187.5 kbps or 19.2 kbps.
The SSW7 is supplied with voltage via the MPI bus from the CPU.
With an optional 24 V connection, it can be used anywhere else on the bus line.
With the Speedup tool included in the scope of delivery, the maximum transmission rate of SSW7 can be achieved with any programming software.
Parameterization and diagnostic functions are possible using the SHTools software.
For a firmware update, download the latest SHTools version.

The SSW7 has automatic baud rate detection on the RS232 interface, which makes it possible for it to adapt to the set bit rate (9.6 to 115 kbps).
