How To Connect To S7 300 Via Ethernet

ETH-MPI(Smart IE) It is used to convert the MPI/DP port of S7-300 PLC into a network port for connecting to the host computer, touch screen, etc. by network cable.

ETH-MPI(Smart IE) Connect the MPI/DP (master master) of the S7-300 PLC to this Ethernet converter and convert it to Siemens Profinet (TCP/IP) Ethernet protocol, which can be connected to STEP7/TIA Portal, WinCC, Siemens SMART LINE touch screen, etc. via the network cable.

STEP 7 Connection Setup

Please follow the link below to download the required drivers.
XP system driver (STEP7): click to download
Win7 32-bit system driver (STEP7): Click to download
Win7/10 64-bit system driver (STEP7/TIA Portal): Click to download

After downloading, unzip it and run ETH_MPI.exe

Then select [install install], after finishing, you can find the ETH-MPI driver option in set the PG/PC interface of Siemens.

Open SIMATIC–>step7–>set the PG-PC interface

Select ETH_MPI and click on Properties. (Properties) and enter 192.168.1.10 in the IP address of the converter.
