Display Indicators
In normal operation, the display shows:
• the current values of the HART variables PV, SV, TV, QV in the selected unit
• the present current output values for the three current outputs in mA
• the current device status
This display shows information about the device status of the field device (1 byte) and
about the response code (1 byte) of the field device. These two bytes are displayed in the
first line of the display in hexadecimal form with the code RC on the left side.
• the current setting of the type of communication
• LOOP Locate
The isolated barrier reestablishes the HART circuit. The isolated barrier performs the field
device query using the HART command 3.
