What are they?

Legacy drivers are software that enable NiagaraAX to communicate with a wide range of meters, sensors and controllers from different manufacturers - even with individual and incompatible protocols that AX does not support

AX is based on the ability to "talk" a lot of different languages (e.g. Modbus, BACNet, LONWorks, etc)

By adding one or more drivers the "multi-lingual" capability of Niagara
AX can be further extended - and can include installed legacy equipment that would otherwise have to be replaced

How is this done?

Legacy Drivers open up two different options

- either leave the entire existing system in place and use a legacy driver to capture data to AX (e.g. to a web supervisor)

- or "decapitate" the existing system and install AX controllers (typically JACEs) and legacy drivers

This brings the advantages of AX: programming with Workbench, history, alarms, dashboards, etc

Legacy Drivers also allow the integration of new sensors and networks using "open" protocols into the legacy system

Why are they useful?

The cost of control elements (e.g. a JACE) is low compared to the cost of installation and re-wiring to replace meters, sensors and actuators

Legacy Drivers make it possible to add Niagara
AX control, monitoring, alarms, history, workbench and dashboards to an existing building at minimum cost by using existing installed elements

With capital expenditure budgets being cut in many areas, it is not just economic sense, but a real necessity, to extend the life of an existing BMS as far as possible. AX plus Legacy Drivers make this possible
