BACnet MS/TP Modules - Built for South African Automation
BACnet MS/TP (Master-Slave/Token-Passing) is a widely adopted open communication standard in building automation and industrial controls, facilitating robust networking between controllers, sensors, and actuators. Whether you're retrofitting legacy plant, deploying HVAC and lighting automation, or scaling your building management system, choosing the right BACnet MS/TP module ensures reliability and interoperability for your South African project.
Communica offers a curated range of BACnet MS/TP interface modules, protocol converters, and peripherals, ready to drop into your BACnet-ready installations across commercial, industrial, and institutional environments.
What is BACnet MS/TP?
BACnet (Building Automation and Control Networks) is an international standard (ISO 16484-5) protocol for building automation. MS/TP is one of its most practical physical layers, using RS-485 serial wiring for token-passing communication among controllers and I/O modules on a daisy-chained network. Typical applications include:
- HVAC controllers (chillers, AHUs, VAV boxes)
- Lighting and occupancy systems
- Energy management and submeters
- Door access and alarms integration

How to Select the Right BACnet MS/TP Module
- Network Size: Check device/node limits and baud rate for your segment (practical: 32-64 per line, up to 1200m with repeaters).
- Physical Interface: Confirm 2-wire RS-485 terminals, galvanic isolation, and mounting format for the panel or enclosure type.
- Interoperability: Is BACnet/IP or Modbus/TCP bridging required? Some modules include dual-stack firmware.
- Electrical Power: Ensure the module operates on existing control panel voltages (commonly 12V or 24V DC).
- Environmental: Higher-grade models withstand temperature extremes and electrical noise - important for SA factories and outdoor applications.
Example Integration - BACnet Module in a BMS
Suppose a facility in Johannesburg is upgrading its chiller system for remote environmental control. The engineering team selects a BACnet MS/TP module with 24V DC input, DIN-rail mount, and supports up to 115.2 kbps. Commissioning involves:
- Connecting RS-485 A/B signal and shielded cabling (Belden 9841 recommended)
- Configuring device MAC addresses below 127 to avoid token loss
- Setting baud rate to match all nodes, using auto-baud where supported
- Verifying communication with the building management system (BMS) via diagnostic LEDs or software tools
Buying Considerations & Local Support
