Features
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 for users to configure the device parameters and build EDS file for the DeviceNet slave device. Users can easily apply Modbus TCP/RTU/ASCII devices in DeviceNet applications through the GW-7243D. The application architecture is depicted as following figure. Users can connect the Modbus TCP/RTU/ASCII devices to the DeviceNet network via the GW-7243D.
