If an error already occurred, this VI returns the value of error in in error out. The default input of this cluster is no error. Refer to NI 5112 Electromechanical Relays for recommended programming practices.Įrror in describes error conditions that occur before this VI runs. Note For the NI 5112, repeatedly resetting the device may causeĮlectromechanical relays. Reset device specifies whether to reset the instrument during the initialization procedure. NI-SCOPE automatically performs this query, so setting this parameter is not necessary. Id query verifies that the digitizer you initialize is one that NI-SCOPE supports. If you use logical names, driver session names, or virtual names in your program, you must make sure that the name you use matches the name in the IVI Configuration Store file exactly, without any variations in the case of the characters. However, all IVI names, such as logical names, are case-sensitive. A virtual name identifies a specific device and specifies the initial settings for the session.Ĭaution Traditional NI-DAQ and NI-DAQmx device names are not case-sensitive. A logical name identifies a particular virtual instrument. You can also pass in the name of an IVI logical name or an IVI virtual name configured with the IVI Configuration utility, as shown in Example 5. Name, the NI-DAQmx device is matched first. If you use the DAQ:: n syntax and an NI-DAQmx device name already exists with that same For example, if the application expects DAQ::1, you can rename the NI-DAQmx device to 1 in MAX and pass in DAQ::1 for the resource name, as shown in Example 4. This naming convention allows for the use of an NI-DAQmx device in an application that was originally designed for a Traditional NI-DAQ device. You can rename an NI-DAQmx device by right-clicking on the name in MAX and entering a new name.Īn alternative syntax for NI-DAQmx devices consists of DAQ::NI-DAQmx device name, as shown in Example 3. Typical default names for NI-DAQmx devices in MAX are Dev1 or PXI1Slot1. MyDAQmxDevice (myDAQmxDevice = device name)ĭAQ::myDAQmxDevice (myDAQmxDevice = device name)įor Traditional NI-DAQ devices, the syntax is DAQ:: n, where n is the device number assigned by MAX, as shown in Example 1.įor NI-DAQmx devices, the syntax is just the device name specified in MAX, as shown in Example 2. Resource name specifies the device name assigned by Measurement & Automation Explorer (MAX).
