Benefits of a TAC/Schneider BAS Upgrade

Your legacy BAS system is considered “closed,” in that it’s only able to communicate with TAC/Schneider brand equipment. This is due to the proprietary programming language and protocols that it uses. A closed system severely limits your ability to select and install equipment from other manufacturers that will help meet the goals of your building.

Upgrading your TAC/Schneider BAS empowers you to select the right equipment from any manufacturer without worrying about compatibility issues. An upgrade will also provide you with many important automation features, such as graphic displays, intelligent algorithms, and powerful reporting. 

Other benefits include:

  • Reducing reliance on obsolete devices, parts, and software
  • Web-based connectivity 
  • Improved energy savings and occupant comfort
  • Ability to run reports and analytics that will allow you to make more informed decisions

TAC/Schneider Integration and Upgrade Options

Your legacy TAC system has Vista front-end software connected to a Xenta controller, which uses a proprietary TAC protocol. The result is a closed system. However, there is good news. 

At Conexus, we can install a go-between controller, such as the Tridium JACE. This will allow us to upgrade your front end to the more modern Niagara without the need to replace the much older Xenta controllers.

How to Know When It’s Time to Upgrade

There are a few key indicators that will let you know it’s finally time to upgrade:

Security Issues

One of the many downsides to running a legacy TAC/Schneider BAS system is that the manufacturer no longer supports it. This means that your system does not have the latest security patches, which can prevent online attackers from stealing your data and causing harm. A modern BAS system gets regular security updates that help keep unauthorized users out.

Deprecated Programming Language

The antiquated computer programming language that powers your legacy TAC/Schneider system makes it extremely challenging to find a qualified technician to perform repairs, maintenance, and upgrades. A new BAS system runs on a more modern programming language that is easier to work on and provides flexibility when it comes time to make changes.

Poor Energy Performance

Your legacy ​​TAC/Schneider BAS system cannot fine-tune performance, which can significantly impact energy efficiency. A newer system makes way for easy tweaks and changes to improve energy usage while ensuring occupant comfort.

Lack of System Memory

Your legacy TAC/Schneider system came with the bare minimum memory needed. This often isn’t enough, and when you run out of memory, it causes the equipment controls, reporting, and other systems to slow to a crawl. A modern BAS system has all the memory you need to ensure smooth performance.

Increased Needs

As time goes by, the needs of your building increase. New tenets, upgrades, and renovations are just a few of the many things that can render your current legacy system obsolete and unable to keep up with the demands of your building. An upgrade to a modern and open system serves to future-proof your BAS for many decades to come.
