The GW-7243D offers the DeviceNet slave and Modbus master functions, and enables the DeviceNet master to access the Modbus slave devices. In the DeviceNet network, the module acts as a Group 2 Only Server device, and waits to build the connection with the DeviceNet master. In the Modbus network, the GW-7243D is a master device, and cyclically sends the commands to access the Modbus slave devices. Both the Modbus TCP client and Modbus RTU/ASCII master interfaces of the GW-7243D can work simultaneously. This feature means that users are able to integrate different kinds of Modbus slave devices together into the DeviceNet network no matter these devices provide Ethernet, RS-232 or RS-485 communication interfaces. In order to simplify the use of the GW-7243D, the GW-7243D Utility tool for configuration and EDS file production is given. This is helpful to build the applications easily and quickly.
The GW-7243D Utility helps users to configure the devices, and has following features:
The simple steps about how to use GW-7243D are described as follows:
| Code | Name | Description |
| 01 (0x01) | Read Coil Status | Read the ON/OFF status of discrete outputs in the slave |
| 02 (0x02) | Read Input Status | Read the ON/OFF status of discrete inputs in the slave |
| 03 (0x03) | Read Holding Registers | Read the binary contents of holding registers in the slaves |
| 04 (0x04) | Read Input Registers | Read the binary contents of input registers in the slaves |
| 05 (0x05) | Write Singal Coil | Force a single coil to either ON or OFF |
| 06 (0x06) | Write Single Register | Preset a value into a single holding register |
| 15 (0x0F) | Force Multi Coils | Forces each coil in a sequence of coils to either ON or OFF |
| 16 (0x10) | Preset Multi Registers | Preset value into a sequence of holding registers |
