Introduction

This article contains instructions on how to send M-Bus data to the server using various protocols.

Configuration overview and prerequisites

Before we begin, let's take a look at the configuration that we are attempting to achieve and the prerequisites that make it possible.

Prerequisites:

• TRB143;
• M-Bus device;
• Server;
• An end device (PC, Laptop, Tablet, Smartphone) for configuration;

If you're having trouble finding any page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Basic" button under "Mode," which is located at the top-right corner of the WebUI.
