M-BUS Protocol

The M-Bus protocol enables OptiFlex Integrators to read data from M-Bus devices, such as water, gas, and energy meters—and bring it into the WebCTRL® building automation system. The WebCTRL system unifies all building systems into one cohesive platform, delivering centralized insights, streamlined management, and comprehensive reporting.

How It Works

The OptiFlex Integrator acts as the M-Bus Master, communicating over a serial port (S1 and/or S2) to the M-Bus Level Converter.

The M-Bus Level Converter converts EIA-485 signals to M-Bus signals and also supplies power to the downstream M-Bus meters.

The OptiFlex Integrator supports up to 80 M-Bus devices (40 devices per serial port) and can manage up to 800 total M-Bus points (400 points per serial port).
