Siemens S7 MPI OPC Server

Kepware's 32 bit Siemens S7 MPI device driver works in conjunction with the OPC Server KEPServerEX, to provide data exchange between OPC Clients and Siemens S7-300 and S7-400 PLCs using 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 your Siemens S7-300 and S7-400 PLCs at either 19.2 KBaud or 38.4 KBaud. The S7 MPI driver talks directly to the MPI adapter cable no additional software packages or libraries are required. KEPServerEX automatically optimizes your data acquisition based on client demand. Data integrity is ensured with our extensive error handling.
