Modbus

The Modbus open standard provides a comprehensive analysis of consumption across various areas of your building. By connecting up to 31 Modbus extension devices within a single Modbus line, you can monitor different types of meters. These include:

Schneider Electric energy meters
Schneider Electric power meters
Schneider Electric Smart Interface Modules (SIM10M module)
Schneider Electric Smartlink
Other Schneider Electric Modbus devices (e.g., SE8000, Modicon PLCs)
Non-Schneider Electric Modbus TCP/RTU devices (offering greater flexibility)

With the information provided by your controller, you can visualize energy or media consumption and implement control strategies within the KNX/IP network to reduce consumption.

Modbus communication details:

Modbus RTU is supported over the RS485 interface.
Modbus TCP is supported over the Ethernet port.
Configure Modbus communication settings using the Modbus tab in the Configurator of your controller.
Easily map Modbus registers using predefined Modbus profiles.

Script-based Modbus control:

Modbus Master can be controlled directly from scripts. Typically, a resident script reads Modbus values at specific intervals and writes them into KNX objects or visualizations.
Add your script in the Script editor, utilizing predefined code blocks from the Helpers.

IMPORTANT: Avoid using Modbus settings via profiles alongside Modbus controlled from scripts. Interference between these settings can lead to communication errors. We recommend prioritizing Modbus device profiles over configuration by scripting.
