Siemens S7 MPI

Product Overview

The Siemens S7 MPI driver exchanges data between OPC clients and Siemens S7-300 and S7-400 PLCs using the MPI protocol. The MPI interface requires the use of the Siemens S7 MPI serial port adapter available from your Siemens dealer. The serial port MPI adapter allows communications with Siemens S7-300 and S7-400 PLCs at either 19.2 KBaud or 38.4 KBaud. The driver talks directly to the MPI adapter cable without additional software packages or libraries. Kepware automatically optimizes data acquisition based on client demand and ensures data integrity through extensive error handling.
