Siemens S7 MPI

Product Overview

The Siemens S7 MPI driver works in conjunction with KEPServerEX to exchange 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 KEPServerEX to communicate 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. KEPServerEX automatically optimizes data acquisition based on client demand and ensures data integrity through extensive error handling.

A driver is a software component that enables KEPServerEX to meet the communication requirements of a specific device, system, or other data source. The driver handles all proprietary communications between the data source and KEPServerEX; KEPServerEX handles all OPC or proprietary client communications between the driver and the client application(s).

Drivers may be licensed individually or in suites. Additional drivers can be licensed on demand as connectivity needs evolve. All OPC client interfaces can connect to KEPServerEX without additional charge.
