Facts at a glance:

  • Parallel communication to 32 PLCs with up to 16 TCP connections
  • Direct PLC to PLC communication, also as projected connection
  • For all S7 Engineering Tools inclusive TIA Portal
  • Web-based configuration, protocol support of RFC1006 and DHCP
  • Full access to PROFIBUS diagnostics and services in STEP7®
  • Automatic DP/MPI baud rate detection



Ethernet to MPI/DP/PPI Converter SIMATIC S7® (for DIN rail)
As directly mountable or as firmly attachable DIN rail mountable device, the adapters netLINK- and netTAPMPI replace expensive CP communications processors and allow the programming, visualization and control of S7-200®, S7-300® or S7-400® PLCs over Ethernet.
The provided driver integrates into all well-known SIMATIC S7® engineering tools like STEP7® or TIA portal. The device is setup with the engineering tool itself or, thanks to embedded Web browser, via conventional Web browsers. The adapters are suitable for programming or modifying S7-PLC control programs and for project engineering of HMI devices via the visualization software WinCC. As it is supported by the "ISO on TCP" RFC1006 Ethernet protocol, any third party or series SIMATIC® type of visualization station can be coupled to the PLC. Once integrated into the office or plant network and connected to the Internet, remote maintenance and logging over a router is also possible, since plain TCP/IP protocol access mechanisms are used. When organized in a network, direct communication between two or several PLCs over Ethernet can be realized. Even a coupling of PLCs without your own Ethernet connection is possible using two adapters in conjunction. Featuring full PROFIBUS diagnostics and Master Class 2 DPV1 services, unrestricted DP Slave device configuration and parameterization is supported in STEP7®. Power is supplied via a 24 V DC. If supported by the S7 PLC, the netLINK-MPI adapter may be powered over the MPI/PROFIBUS connector, as well. The extra feed-through DSUB9 connector provides for connecting other devices to the same MPI/DP network.
