List of Available HART Commands
SVI II AP Monitor Screen
 017 Write Message - This command allows the user to enter a message (up to 32
characters) that is stored in the SVI II AP.
 018 Write Tag & Descriptor - This command allows the user to enter a tag name (up
to 8 characters) and a description (up to 16 characters) that are stored in the
SVI II AP.
 19 Write Final Assembly - This command allows the user to enter an identifying
number (0 to 16 million) which is stored in the SVI II AP.
 038 Reset Configuration Changed Flag - This command sets the HART configuration
changed bit back to 0. The bit is set whenever a value in the device has changed.
 072 Squawk - Send this command using ValVue and a specific device audibly
indicates the reception of the command.
 210 Read Configuration - Reads the configuration data from the device and displays
it in the response box. The data includes all of the data describing the device set on
the Configure screen including Air-To-Open/Air-To-Close, Tight Shutoff status,
Software Position Limit Stops, etc.
 200 Read Option Configuration - Reads basic (hardware) configuration information
about the positioner.
 211 Read Custom Characterization – Reads the custom characterization information
about the positioner.
 212 Read Error Limits - Reads and displays the position range and time-outs
associated with position and pressure errors
 213 Read Calibration Data - Reads and displays the input signal that corresponds to
the open and closed positioning of the valve.
 216 Read PID - Reads and displays the valve positioning tuning parameters
 136 Read Status - Reads and displays the status flags. These flags describe error
conditions that have occurred since the last time they were cleared. See “Status
Code List” on page 150 of this manual for a complete list of possible codes.
 138 Clear Status - Clears the status flags. See also “Status Code List” on page 150.
 142 Read Switches - Reads the status of the contact switches
 139 Read Continuous Diagnostic Data - Reads and displays the continuous
diagnostic data including number of full strokes the valve has made, the number of
cycles (direction changes), the time the valve has spent open, the time the valve has
been closed, and the time the valve has spent throttling near the seat
 191 Read Standard Diagnostic Data - Displays the valve response time open and
response time closed
 154 Read Setpoint - Reads the manual setpoint of the positioner.
 141 Read Raw Data - Returns information from the SVI II AP that is useful to
engineers for diagnostic purposes. The information includes the input current on the
auxiliary input channel, the A/D values from the pressure, signal, and position
