ETH Adapter CN:Siemens S7-300/400PLC Ethernet adapter


Siemens S7-300/400PLC Ethernet adapter,is used for the communication between S7-300/400PLC and Ethernet,Internet or 3G wireless network by the MPI or DP interface.No need to revise the communication protocol and software, support Dynamic DNS, user can remote control the PLC by the internet. The RJ45 port,RS485 interface and power supply port are all isolated in order to suit harsh environment in the industrial scene.

ETH Adapter CN is the industrial product which use the Ethernet and Internet or 3G wirelss network to achieve Siemens S7-300/400PLC networking communication. It integrates many complex network protocols, support TCP Server,TCP Client,UDP Unicast,UDP Multicast etc many modes.It has 10M/100M adaptive Ethernet interface and MPI and PROFIBUS interface which meets Siemens technical specifications.You only need to go on simple setting and then let the S7-300/400PLC go on network communication.

The RJ45 port,RS485 interface and power supply port are all isolated in order to suit harsh environment in the industrial situations. Especially the isolated power supply port and each signal pin has anti-static protection and surge protection which can solve the PLC communication port easily damaged problem.
