channelName
Variable Type ViChar[]
If the attribute is channel-based, this control specifies the name of
the channel whose attribute is to be retrieved. If the attribute is
not channel-based, then you set this control to empty string or
VI_NULL.
Pass the virtual channel name that you assign to the instrument in
the Configuration Utility.
Virtual channel names are aliases for instrument-specific channel
strings. The instrument-specific channel strings can differ from one
instrument to another. Virtual channel names allow you to use and
swap instruments without having to change the channel names in your
source code. You assign a virtual channel name to an
instrument-specific channel through the Configuration Utility. This
control accepts virtual channel names you have assigned to the
specific instrument you are using. It also accepts the
instrument-specific channel names.
Default Value: ""
Notes:
(1) You can specify the channel name as a string variable or as a
literal enclosed in double quotes.
attributeID
Variable Type ViAttr
Pass the ID of an attribute.
From the function panel window, you can use this control as follows.
- Click on the control or press , , or
, to display a dialog box containing a
hierarchical list of the available attributes. Help text is
shown for each attribute. Select an attribute by
double-clicking on it or by selecting it and then pressing
.
A ring control at the top of the dialog box allows you to see
all IVI attributes or only the attributes of the ViString
type. If you choose to see all IVI attributes, the data types
appear to the right of the attribute names in the list box.
Attributes with data types other than ViString are dim. If
you select an attribute data type that is dim, LabWindows/CVI
transfers you to the function panel for the corresponding
function that is consistent with the data type.
- If you want to enter a variable name, press to change
this ring control to a manual input box.
