The positioner is also available with built--in HART-functions. The
HART protocol allows you to communicate with your instrument with a
handheld communicatorR, PC or programming unit. This enables you
to configure your instrument comfortably, save configurations, call dia-
gnostic data, display online measured values and much more. Commu-
nication takes place as frequency modulation over the existing signal
lines for the command variable from 4 to 20 mA.
