HMI-S71200(SMART screen connected to S71200/1500)

Siemens SMARTLINE touch screen has a high cost performance, but can only be used to connect S7-200. HMI-S71200 is a protocol conversion gateway for Siemens PLC with Ethernet interface (S7-1200, S7-1500, S7300PN, etc.) and Siemens SMART IE touch screen Ethernet communication.
HMI-S71200 has two physical interfaces, LAN1 and LAN2 respectively have independent local area network capability. The LAN1 port is a dual RJ45 port with switch function, which is mainly used to connect PLC; the LAN2 port is a single port RJ45 port, which is mainly used for the connection of SMART IE touch screen.

HMI-S71200 function

  1. Installed on a 35mm guide rail, LAN1 is a dual-port RJ45 with switch function, and this port is connected to PLC; LAN2 is a single-port RJ45, which can be connected to a SMART IE touch screen; HMI-S71200 needs an external 24VDC power supply;
  2. Integrate the WEB server, through the webpage, you can set the device parameters and run diagnosis; you can also configure it through the BCDevice tool; you can configure it from the LAN1 or LAN2 port at will;
  3. Realize the NAT function, map the IP address and port number of the PLC connected to the LAN1 port to any IP and port number of the LAN2 port;
  4. The SMART IE series touch screen can be connected to S7-1200, S7-1500, S7300PN and other PLCs;
  5. Support up to 32 LAN2/LAN1 server/client concurrent models, LAN2 port can support up to 8 SMART IE touch screen connections;
  6. Support firmware update on the user side through Ethernet, provide firmware with more functions for free, buy hardware once, and upgrade permanently.
