The BACnet MS/TP Controller (750-829) connects the WAGO I/O System to the BACnet protocol and supports the B‐BC BACnet device profile per DIN EN ISO 16484‐5. It communicates with other BACnet devices via BACnet MS/TP.

The controller provides the three following functionalities:


  • 1. Native server: For each channel, appropriate BACnet objects are generated automatically for the digital and analog I/O modules that are connected to the controller.
  • 2. Application server: Other supported BACnet objects can be created via IEC 61131‐3 programming environment and made available to a BACnet network.
  • 3. Application client: Using the client functionality, objects and their properties can be accessed by other BACnet devices.

The IEC 61131-3 programmable controller is multitasking-capable and features a capacitor-backed RTC.

The ETHERNET service interfaces can be used for IEC downloads, for example. Furthermore, two ETHERNET interfaces and an integrated switch allow the ETHERNET fieldbus to be wired in a line topology. This eliminates additional network devices, such as switches or hubs. Both interfaces support autonegotiation and Auto-MDI(X).

An integrated Webserver provides configuration options to the user, while displaying the controller's status information. The Webserver cannot be used via BACnet MS/TP.


For initial start-up, access to the Web-Based Management (WBM) via standard Web browser is required to set the baud rate and activate the MS/TP fieldbus. Further configuration and commissioning is performed via WAGO BACnet Configurator's Windows software (V1.8 or higher) and requires an additional BACnet router within the network.

The Protocol Implementation Statement (PICS) contains all supported objects, services and properties. The controller supports a maximum of 250 BACnet objects.

A slide switch enables the switching on of a terminating resistor together with the BIAS network on the RS-485 interface.
