Overviews of related technology, protocols such as BACnet and Modbus , and whitepapers on auditing and controls methodologies will be documented here.
Modbus
Modbus is a commonly-used industrial communications protocol. It was originally designed for Modicon (Schneider Electric) PLCs, but is now a de facto standard protocol used by many product manufacturers.
BACnet
BACnet is a communications protocol for building automation and control. Compared to the simplicity of the Modbus protocol, BACnet is much more complex and attempts to provide high-level functionality like auto-discovery of devices.
