Isolated Ethernet Gateway

General Description

The Isolated Ethernet Gateway DAT3580GW connects Modbus RTU RS485 serial devices to Modbus TCP Ethernet protocol.
The DAT3580GW Isolated Ethernet Gateway has a built in web server which makes it possible to set up the Modbus TCP IP Address, Subnet mask, and parameters of the Modbus RTU device.
Using the DAT3580GW with a control system enables up to 8 clients to be connected at the same time. Sending a command to the DAT3580GW over the Ethernet is processed and re-transmitted to the Modbus RTU devices which respond and return the information to the client which sent the request. It is possible to configure the Modbus RTU device with the integrated web server on the DAT3850GW.
