Modbus

In this document, we will focus on the Modbus/TCP server.

Ned is permanently running a Modbus TCP Server that enables Ned to communicate with a PLC, or another computer in the same network.

The Modbus/TCP server is running on port 5020 by default. It has been built on top of the pymodbus library. This enables you to make Ned communicates with a PLC, or another computer on the same network.
