Schneider Electric TAC Xenta 913 Programmable Controller

The Schneider Electric TAC Xenta 913 is a programmable gateway controller that works with many different protocols. It is meant to bring together different building automation and industrial systems into one IP-enabled control platform. It works well for HVAC, energy metering, lighting, and plant equipment when Modbus, BACnet, M-Bus, LonWorks, I/NET, and other protocols need to work together without any problems.

The TAC Xenta 913 is a small, 24 V controller that has robust gateway and server functions and can communicate with a variety of devices. It is the main point of integration between field devices, existing control networks, and higher-level BMS platforms like TAC Vista.

TAC Xenta 913 Technical Specifications

Functions of the gateway and server

The TAC Xenta 913 does more than only convert protocols; it also serves as a powerful gateway and Xenta Server in a TAC network. It makes all associated points clear to TAC Vista and other tools for supervision.

Core Functions:

• Moves real-time values between LonWorks/I/NET and devices that use Modbus, BACnet, M-Bus, or C-Bus.
• Allows value exchange in both directions, so outside systems can both watch and control BMS points.
• It works as a TAC Xenta server to send LonWorks, I/NET, and third-party data to higher-level software over TCP/IP.

TAC Xenta 913 Key Features:

1) Multi-Protocol Gateway Support: This product works with Modbus (RTU/ASCII/TCP), BACnet (MS/TP/IP), LonWorks, M-Bus, I/NET, and Clipsal C-Bus protocols to make communication between HVAC, lighting, and energy systems easier.

2) Communication Ports That Can Be Changed: Control panels and field networks can connect to this device by RS232/RS485 serial interfaces, Ethernet 10Base-T, and LonWorks TP/FT-10.

3) Bidirectional Data Exchange: Lets you monitor and operate field devices, third-party systems, and upper-level BMS platforms like TAC Vista in real time.

4) Low-profile IP20 enclosure (0.2 kg) with a compact DIN-rail design makes it easy to mount in automation cabinets. It also uses very little power (max 5 W at 24 VAC/DC).

5) Intuitive Configuration: Set up using TAC XBuilder software to map points, set logic, and give structured names to things on different networks.

6) Strong Real-Time Clock: It is accurate to within ±12 minutes per year and has a 72-hour backup, so scheduling and time-stamped logging will still work during power outages.

7) Scalable Modbus Handling: Can handle up to 31 master devices or 100 TCP clients, and it has important functions (01-06, 10) that work with a wide range of devices.

8) Future-Proof IP Integration: Works as a TAC Xenta Server over Ethernet, giving IP-based supervisory tools access to all points for remote access and scalability.

Communication options:

• RS‑232 and RS‑485 serial channels for Modbus, M‑Bus, C‑Bus and other ASCII/RTU devices.

• Ethernet (TCP/IP) interface for BACnet/IP, Modbus TCP, and connection to TAC Vista and other IP systems.

• LonWorks/I/NET side for seamless integration into existing TAC networks and controllers.

Configuration and programming

The TAC XBuilder engineering tool is used to set up the TAC Xenta 913. It connects data points between networks and sets up gateway logic. This provides system integrators a lot of freedom and power.

Applications:

The TAC Xenta 913 is a popular choice for a cost-effective integration node in modern building management systems. It lets facilities teams link old and new equipment without having to replace all of the control networks.

1. Using Modbus or BACnet to connect chillers, boilers, AHUs, VAV controllers, and BMS-ready drives to TAC Vista.
2. Getting energy and utility information from M-Bus meters for central logging, dashboards, and billing.
3. Connecting lighting and security systems (such Clipsal C-Bus and I/NET) to the primary building management platform.
