Controls

BACnet MSTP and BACnet IP are both widely used communication protocols in commercial HVAC and Building Management Systems (BMS), but they serve different applications and have different performance characteristics.

BACnet MSTP

Operates over RS-485 (twisted pair).

All devices share a single communication trunk in a token-passing loop.

Lower bandwidth, typically 9.6–76.8 kbps.

Very stable when installed correctly but sensitive to cable quality, grounding, and addressing issues.

Regular BMS maintenance keeps HVAC systems efficient, compliant, and energy-smart. Learn how Australian facilities can reduce costs and extend equipment life.

As buildings become smarter, the Building Management System (BMS) is the heart of every modern facility. Yet many sites in Australia still run outdated or poorly maintained systems.

Routine BMS servicing helps identify hidden inefficiencies, sensor drift, and faulty control logic that drive up power bills.

Whether you’re running Niagara N4, Reliable Controls, or Optergy, scheduling quarterly or bi-monthly maintenance ensures chillers, AHUs, and CO₂ systems operate in sync.

Investing in BMS optimisation often returns 10–20% energy savings within months.

In today's rapidly evolving HVAC industry, professionals seek control solutions that offer flexibility, scalability, and cost-effectiveness without compromising performance. Enter open-source controllers, specifically, the powerful combination of WAGO controllers and the CODESYS platform. Here's why HVAC professionals, integrators, and decision-makers should strongly consider making the switch.

💰Cost Savings & Licensing Freedom

One of the most compelling advantages of adopting CODESYS V3.5 is its cost efficiency. Unlike proprietary systems with expensive upfront licensing and recurring fees, CODESYS provides a comprehensive, fully-functional Integrated Development Environment (IDE) completely free of initial charges. This licensing freedom ensures your organization avoids vendor lock-in, drastically reducing operational expenditures and enhancing long-term profitability (Wikipedia, WAGO AU). It is important to note that while end-users and integrators benefit from free use, WAGO itself covers licensing fees to embed and redistribute the CODESYS runtime environment in their controllers.
