ETH-300-2P
ETH-300-2P for Ethernet data acquisition of Siemens S7-300 PLC, supports most SCADA software in industrial control field, and supports Siemens S7TCP Ethernet protocol and ModbusTCP protocol.
The DB9 pin female port of ETH-300-2P expansion is a bridged type, which can be connected to Siemens, Kunlun Tongshi, Weilentong, Delta, Bucco, USB-PPI programming lines, etc., without occupying the PLC programming port, and has wide practicability.
In addition, ETH-300-2P can communicate with 200PLC without obstacles after changing the module communication mode to PPI mode on the web page.
Note: ETH-300-2P requires that the baud rate of the touch screen be lower than that of the PLC to connect the touch screen, and if it is connected to the Siemens touch screen, the number of client connections cannot be too large. In case of abnormal communication, it is necessary to reduce the number of client connections.
