Modbus RTU to OPC-UA conversion

Looking to use Raspberry Pi as edge device. Want to import Modbus RTU/ASCII data from legacy controllers, format and wrap in OPC-UA in order to transmit to Amazon AWS cloud service.
Would Node-Red be capable of handling such a conversion?

Yes. Node-red does modbus and OPC UA. Just be sensible when requesting data from modbus devices (favour reading many items in a single modbus request over reading many single values). Node-red-contrib-buffer-parser can assist in converting the raw modbus values to proper types before serving via OPC UA.

Thank you...
