The GW-7243D is one of DeviceNet products in ICP DAS and it stands as a DeviceNet slave to Modbus TCP/RTU/ASCII master gateway device. It allows a master located on a DeviceNet network to enter a dialogue with slave devices on the Modbus TCP/RTU/ASCII network. In DeviceNet network, it functions as a “Group 2 Only Server” device. In Modbus network, GW-7243D represents a master device and sends request message to access the Modbus TCP/RTU/ASCII slave device by DeviceNet  object definition. In order to simplify the protocol converting mechanism, we also provide the GW-7243D Utility tool to configure the device and build EDS file for the DeviceNet slave device.
