Hi,

The UWC middleware reference contains Modbus RTU and Modbus TCP services for exchanging data from/to sensors' and actuators' coils, holding registers, etc. 

Thank you for the question.   Someone will respond with a complete answer.  if you are interested to investigate further yourself, a user guide is available after downloading the UWC package.  https://software.intel.com/iot/edgesoftwarehub/download/home/ri/universal_wellpad_controller

The Softdel-based stack used in the Intel UWC supports below below Function Codes -

• 01 coil
• 02 discrete input
• 03 holding register
• 04 input register
• 05 write single coil
• 06 write single register
• 10 write multiple register

The stack supports multiple queues for message prioritization.
