GW-7473 Modbus TCP/RTU Slave to EtherNet/IP Scanner Gateway Diagram

The GW-7473 Modbus TCP/RTU Slave to EtherNet/IP Scanner Gateway is helpful for data-exchanging between Modbus Master and EtherNet/IP adapter. It reads the register data from the EtherNet/IP adapter and publishes these data to the input register data of the Modbus TCP client as well as Modbus RTU Master. The output data transmitted by the Modbus TCP/RTU Master and is updated to the register data of the EtherNet/IP adapter. In order to save the installation space, the GW-7473 is also offered in an amazing tiny form-factor that makes it easy to install in anywhere, even directly attached to a serial device or embedded into a machine. The GW-7473 features a powerful 32-bit MCU to handle efficient network traffic and it provides the IEEE 802.3af-compliant (classification, Class 1) Power over Ethernet (PoE) with a standard category 5 Ethernet cable. Through the NS-205PSE, Poe switch, the GW-7473 can be powered via the Ethernet cable. When there is no PoE switch on site, the GW-7473 provide another way to be powered from DC adapters. These two power interfaces are redundant. If one fails, another will take it over to supply the proper power to the GW-7473.
