Concepts apply to Honeywell, Siemens, Johnson Controls, Schneider, Trane and Distech; the hands-on modules use open BACnet with Python.

Is BMS the same as PLC programming?

It shares the logic but uses BACnet, KNX and DDC controllers and a different vocabulary of HVAC, lighting and access control. The courses start from that vocabulary.
