Look into Modbus data to server via MQTT section for Modbus Slave and Master setup. Navigate to navigate to '''Services -> Data to server.''' Add new data sender and configure settings accordingly:
*'''Enable''': on
*'''Name''': tcp (input any preferred name)
*'''Data source''': MODBUS data
*'''Protocol''': HTTP(S)
*'''JSON format''': {"Data": %a} - adjust this according to your needs
*'''Segment count''': 1
*'''URL/Host/Connection string''': 192.168.10.139:8080 (virtual machine address and port number)

For this configuration we are going to need two nodes: '''TCP''' and '''debug'''. Drag in both nodes and click on TCP node. Adjust settings accordingly:
*'''Type''': Listen on port '''8080'''
*'''Output''': stream of '''String''' payload
