Device and method for routing serial traffic of a building management system

A method of a building controller for routing serial traffic to a remote device of a building management system, the method comprising:

• reading non-IP serial traffic from a non-IP network of building devices managed by the building controller;
• framing, by an MSTP datalink layer of the building controller, the non-IP serial traffic into serial traffic packets;
• forwarding the non-IP serial traffic to a building network stack operating on the building controller, wherein the building controller performs building controller operations based on data stored at the building network stack, and wherein the building network stack provides the non-IP serial traffic to one or more controller components of the building controller for performing the building controller operations;
• forwarding the non-IP serial traffic, or a duplicate thereof, from the building network stack to a frame router operating on the building controller in response to detecting that remote traffic monitoring has been enabled;
• identifying, by the frame router, a destination interface of the building controller to route the non-IP serial traffic;
• generating, by the frame router, a data packet that includes the non-IP serial traffic and an IP header;
• and
• providing the data packet by a TCP server running in the building controller to an IP network of building management devices connected to the building controller, wherein the TCP server identifies a TCP port of the building controller corresponding to a destination on the IP network based on a configuration of the serial traffic analyzer operating at the remote device, the building management devices including the remote device of the building management system connected to the IP network, the remote device having a serial traffic analyzer operating at the remote device.
