Command Result Display
Command Result Display
This box displays the SVI's response to HART commands. The following commands may be
sent to the SVI:
 000 Read Identifier - Returns the unique identifier from the device including the
device ID, device type, and the manufacturers ID.
 001 Read Primary Variable - Returns the position in percent open.
 002 Read Current - Returns the input signal in mA.
 003 Read All Variables - Returns the input signal and the position in percent open.
 011 Read ID from Tag - Prompts you for a tag name. The tag name is sent in a HART
command and if received by a device with a matching tag name, the ID of the device
is returned. The format of the ID is the same as command 001 Read Identifier.
 012 Read Message - Reads the message that was stored in the device when it was
configured.
 013 Read Tag & Descriptor - Reads the tag name, date, and the descriptor that was
stored in the device when it was configured.
 016 Read Assembly Number - Reads the final assembly number that was stored in
the device when it was configured.
 017 Write Message - This command allows you to enter a message (up to 32
characters) for storage in the SVI2.
 018 Write Tag & Descriptor - This command allows you to enter a tag name (up to 8
characters) and a descriptor (up to 16 characters) that are stored in the SVI2.
 019 Write Final Assembly - This command allows you to enter an identifying number
(0 to 16 million) which is stored in the SVI2.
 038 Reset Configuration Changed Flag - This command sets the HART configuration
changed bit back to 0. The bit is set whenever a value saved in the device is changed.
 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 tab including Air-To-Open/Air-To-Close, Tight Shutoff status, Software
Position Limit Stops, etc.
 200 Read Option Config - Reads basic (hardware) configuration 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 position of the valve.
 216 Read PID - Reads and displays the valve 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 653 for a complete list of possible codes.
 138 Clear Status - Clears the status flags. See“Status Code List” on page 653.
 137 Read Switches - Reads the status of the contact switches.
