niHSDIO Tristate Channels
Forces a channel into a high-impedance state. The effect is immediate; it does not require the session be committed. The channel remains tristated regardless of what other software commands are called. Call this VI again and wire FALSE to the tristate terminal to allow other software commands to control the channel normally.
Channels stay tristated while the session remains open. Closing the session does not affect the high-impedance state of the channel, but future sessions can now control it.

instrument handle identifies your instrument session. instrument handle was obtained from the niHSDIO Init Acquisition Session VI or the niHSDIO Init Generation Session VI. | ||||||
 |
channel list identifies which channels will be tristated. Channels not specified in this list are unaffected.
Syntax examples: "2-15" or "0-3, 5, 8-15", or "0, 3, 10." |
||||||
 |
tristate specifies whether the channels specified in channel list remain tristated. If tristate is TRUE, the channels specified in channel list remain tristated, ignoring future software commands. If tristate is FALSE, the channels specified in channel list can have the tristate condition removed by future software commands. | ||||||
 |
error in describes error conditions that occur before this VI or function runs.
| ||||||
 |
instrument handle out passes a reference to your instrument session to the next VI. instrument handle was obtained from the niHSDIO Init Acquisition Session VI or the niHSDIO Init Generation Session VI. | ||||||
 |
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.
