  • 04 input register
  • 05 write single coil
  • 06 write single register
  • 10 write multiple register

The stack supports multiple queues for message prioritization.

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
