I am using a project which was run and working properly using NI PXIe 8133, Now i want to use the same project at NI PXIe 8840.
I drag all VI and subVI into NI PXIe8840 and run the main VI, But it shows an error that "Error - 200220 occurred at DAQmx Create Channel (Al-Voltage-Basic.vi: 1780001)
The device identifier is invalid.
Specified device: PXI2 Slot 5
Recommended Devices: PXI1 Slot 7, PXII1 Slots 14
Task Name: unnamed Task < 175A >
I add the screenshots of main VI and my project
When i run it in SubVI, It works normally and there is no error detected.
