Modbus RTU (Remote Terminal Unit) is an open, serial (RS-232 or RS-485) protocol derived from the Master/Slave architecture. It is a widely accepted protocol due to its ease of use and reliability. Modbus RTU is widely used within Building Management Systems (BMS) and Industrial Automation Systems (IAS).
SoftDEL offers a ready Modbus RTU Master and Slave Stack on royalty free basis. The stack enables faster firmware development of Modbus-enabled field devices. The stack is useful for OEMs who wish to add Modbus RTU support for their field devices.
We also offer services such as porting of Modbus stack to device platform, integration with device application and complete product testing.
