HMI-S7300(SMART screen connected to S7-300/400)

Siemens SMARTLINE touch screen has a high cost performance, but can only be used to connect S7-200. HMI-S7300 can realize the method of connecting S7-300/400 Ethernet to SMARTLINE touch screen.
HMI-S7300 can be directly plugged into the MPI/PROFIBUS port of Siemens S7-300/400, convert MPI/PROFIBUS protocol to S7TCP protocol, and connect Siemens SMARTLINE touch screen via Ethernet.
HMI-S7300 does not need an external power supply and does not occupy the PLC programming port. While the touch screen communicates with the PLC through Ethernet, the programming cable and other master stations can communicate with the PLC through the extended RS485 port.

HMI-S7300 function

  1. It can realize SMART IE series touch screen Ethernet connection to Siemens S7-300/400 series PLC;
  2. The Ethernet interface can support up to 8 SMART IE touch screen connections;
  3. Support firmware update on the user side through Ethernet, provide firmware with more functions for free, purchase hardware once, and upgrade permanently.
