VISA VXI Cmd or Query

Sends the device a miscellaneous command or query and/or retrieves the response to a previous query.

VISA resource name specifies the resource to be opened. This control also specifies the session and class. Refer to VISA Resource Name Control for more information.
mode specifies whether to issue a command and/or retrieve a response. The following modes are available:

Mode Action Description
VI_VXI_CMD16 (0x0200) Send 16-bit Word Serial command.
VI_VXI_CMD16_RESP16 (0x0202) Send 16-bit Word Serial query; get 16-bit response.
VI_VXI_RESP16(0x0002) Get 16-bit response from previous query.
VI_VXI_CMD32 (0x0400) Send 32-bit Word Serial command.
VI_VXI_CMD32_RESP16 (0x0402) Send 32-bit Word Serial query; get 16-bit response.
VI_VXI_CMD32_RESP32 (0x0404) Send 32-bit Word Serial query; get 32-bit response.
VI_VXI_RESP32 (0x0004) Get 32-bit response from previous query.

Note  The mode you specify can cause all or part of the command or response parameters to be ignored. The possible results of specifying a particular mode are the following:
  • If mode specifies sending a 16-bit command, the upper half of command is ignored.
  • If mode specifies retrieving a response only, command is ignored.
  • If mode specifies sending a command only, response is ignored. You can use VI_NULL for the value of response.
  • If mode specifies to retrieve a 16-bit value, the upper half of response is set to 0.
command is the miscellaneous command to send.
error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
code is the error or warning code. The default is 0. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
dup VISA resource name is a copy of the VISA resource name that is passed out of the VISA functions. Refer to VISA Resource Name Control for more information.
response is the response retrieved from the device. If the mode specifies to send a command rather than retrieve a response, you can use VI_NULL for this parameter.
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
code is the error or warning code. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
