IMAQ IO Enable Shutdown

Use IMAQ IO Enable Shutdown to enable the NI-IMAQ I/O device to handle fault conditions and detect user shutdown. If you do not enable shutdown on the NI-IMAQ I/O device, the settings you define in the IMAQ IO Write Shutdown States VI do not take effect. Refer to your hardware documentation for more information about the NI-IMAQ I/O device shutdown configuration settings and effects. Details

Caution  When Shutdown mode is enabled and the shutdown input signal, ISO Inputs.In 11, turns off, the NI-IMAQ I/O device registers an external shutdown condition. Refer to your hardware documentation for information about the device shutdown behavior.

Caution  Because the shutdown states are stored in volatile memory, you must configure the NI-IMAQ I/O device shutdown actions each time your system is booted.

	Resource In is a string input that represents the name of the device to enable shutdown for. You can select the device name from the list of devices on your machine, or you can type the name and IP address of the device you want to target. In the list of device names, the names are the VISA name for the device, which is defined in Measurement & Automation Explorer (MAX). For example, the device name might be similar to RIO#::INSTR, where # represents the number of the RIO device, depending on how many RIO devices are installed in the system.
	Enable Shutdown allows you to configure the NI-IMAQ I/O device to control outputs when a fault condition occurs. When you set Enable Shutdown to TRUE, the NI-IMAQ I/O device uses the settings you specify in the IMAQ IO Write Shutdown States VI.
	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 occurred 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 if an error occurred before this VI or function ran or FALSE 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 nonzero 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.
	Resource Out is a string output that represents the name of the device.
	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 if an error occurred or FALSE to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero 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.

Using This VI

Note  Clear shutdown by powering off and then powering on your system.

Caution  Because the shutdown states are stored in volatile memory, you must configure the NI-IMAQ I/O device shutdown actions each time your system is booted.
