HART Protocol and Device
Description (DD) Information
Valve Automation electric motor actuators equipped with CAM16/216 option use HART
protocol to communicate with other HART devices and a compatible host system. The HART
Communications Protocol communicates over 4-20mA instrumentation cable which permits
an easy upgrade path for legacy instrumentation systems to migrate into a digital industrial
automation protocol.
A HART DD is used to describe the characteristics of the field device to the Host. For more
details on the Device Descriptor (DD) please refer to
When manual installation of the DD is required, please refer to the Emerson Website to find the
latest version of the HART CAM16/216 for download. Alternatively, the DD can be downloaded
directly from the HART Foundation website at
Navigate to Technology | Device Descriptions | DD library | Product Catalogue | and locate
the CAM16 or CAM216 DD respectively.
