Modbus® TCP/IP to Siemens® Industrial Ethernet Communication Gateway


ProSoft Technology’s Modbus® TCP/IP to Siemens Industrial Ethernet gateway allows high speed bi-directional data transfers between Schneider Electric® PACs and Siemens S7 and S5 PACs.

Two ports allow each protocol to reside on separate subnets, allowing you to pass data between the two subnets without changing each device’s IP address.

Caractéristiques Avantages

  • Two separate Ethernet ports allow each protocol to reside on separate subnets. This allows you to pass data between the two subnets without changing each device’s IP address to be on the same subnet. 
  • In addition to S7 controllers, the gateway can also be used with Siemens S5 controllers with an appropriate interface. 
  • Gateway includes a SD card slot (SD card optional) for storing configuration files. This can be used for disaster recovery. 
  • Secure module configuration via module switch (v1.04 and greater). 
  • Up to 4000 16-bit registers can be used to exchange large amounts of data
