Modbus Viewer: Retrieve Data from Devices through Modbus TCP/IP Protocol
Modbus Viewer is a free Android application developed by Dmitrii Mitriaev, categorized under Utilities & Tools. It comes with two apps: Serial App and Modbus TCP/IP App. The Serial App supports the PL2303 chip and allows only writing, while reading is unavailable. The Modbus TCP/IP App allows retrieving data from devices through the Modbus TCP/IP protocol. The app comes with a scanner that facilitates finding relevant addresses.
The Modbus Viewer supports several functions, including 01 Coil status (0x), 02 Input status (1x), 03 Holding registers (4x), 04 Input registers (3x), 05 Write single coil, 06 Write single register (type), 15 Write multiple coils, 16 Write multiple registers (type), and My request. If you encounter any bugs, please contact the developer.
Overall, Modbus Viewer is a useful tool for retrieving data from devices through the Modbus TCP/IP protocol. However, it would be better if the Serial App could support reading as well.
