Note
• Operation at the positioner has priority over specifications from the HART communicator.
• Failure of the auxiliary power to the positioner also interrupts communications.

you to communicate with your device through a handheld communicator, PC, or
programming unit. You can do the following with your device:
● Convenient configuration
● Store configurations
● Call up diagnostic data
● Show online measured values
Communication takes place as frequency modulation on the existing signal lines for the
control values of 4 to 20 mA.
The positioner is integrated into the following parameterization tools:
● Handheld Communicator
● PDM (Process Device Manager)
● AMS (Asset Management System)
● Cornerstone (without diagnostic values/functions)
