GW-7472 EtherNet/IP to Modbus RTU/TCP Gateway

Description

The GW-7472 (EtherNet/IP adapter to Modbus RTU Master and Modbus TCP Client Gateway) is used to exchange data between a Modbus RTU or Modbus TCP Network and an EtherNet/IP Network. It reads the register data from the Modbus RTU slaves as well as Modbus TCP servers and publishes this data to the input register data of the EtherNet/IP scanner. The output data transmitted by the EtherNet/IP scanner is sent to the registers of the Modbus RTU slaves/Modbus TCP servers via the GW-7472.

The GW-7472 is supplied in a very small form-factor enclosure for ease of installation, such as being directly attached to a serial device or embedded into a machine. The GW-7472 features a powerful 32-bit MCU to efficiently handle network traffic and is is IEEE 802.3af-compliant (classification, Class 1) Power over Ethernet (PoE) with a standard category 5 Ethernet cable. Through using the NS-205PSE PoE switch (or similar), the GW-7472 can be powered via the Ethernet cable. Alternatively if there is no PoE switch on site, the GW-7472 can be powered from DC adapters. These two power interfaces can both be used and are redundant, so if one fails, the other will take over supply to the GW-7472.
