Description
Specifies if the channel is available for external connections or if the channel is internally used for path creation. If this attribute is set to VI_FALSE, then the channel is considered a standard channel and can be explicitly connected to another channel. If the value is set to VI_TRUE, then the channel is no longer accessible to you and has been turned over to the driver for its use. The purpose of this attribute is to tell the driver what channels are available for path creation. For example, if you specify a column-to-column connection in a matrix, it typically must use at least one row channel to make the connection. Specifying a channel as a configuration channel allows the instrument driver to use it to create the path.
After a channel has been configured as a configuration channel, then no operation can accept this channel name except for IviSwtch_GetAttribute and IviSwtch_SetAttribute for this attribute only.
