Known IssuesniSE_OpenSession and niSE Open Session.vi Memory Leak
The LabVIEW VI "niSE Get Ivi Device Session.vi" leaks a small amount of memory each time it is called. The memory will be freed when LabVIEW exits. Try to avoid calling this function multiple times if it can be avoided.
Instrument Drivers
If you install NI Switch Executive without having previously installed NI-SWITCH, it is possible that the NI-SWITCH VI's might not get installed for LabVIEW. To workaround this problem, install NI-Switch from the CD that came with your hardware before installing NI Switch Executive.
"DLL Not Found" - Microsoft Visual Basic
If you are using the SCXI-1127 in multiplexer mode, there are a few anomalies exposed by NI Switch Executive. First, the SCXI-1127 supports different wire modes (1, 2, or 4 wires) as configured through NI-DAQ. Through NI Switch Executive, however, you may only use it with 2 wire channels. Second, the list of channels retrieved from the instrument driver includes all of the channel names as though it was configured as a 1 wire switch. Because of this, half of the channels may appear valid in NI Switch Executive but actually are not. Consult the SCXI-1127 hardware reference manual and NI-SWITCH user manual for a list of which channels are valid 2 wire channels. In NI Switch Executive you will need to ignore those channels which are not valid. This behavior will be fixed with a future NI-SWITCH release.
Installation failure on Windows 95 and NT
The IVI configuration of an IVI switch is read at the time that the switch is added to the NI Switch Executive Virtual Device. If changes are made to the IVI configuration, such as creating virtual channels or changing default setup to make some channels come up as source or configuration channels, those changes will not automatically be reflected in NI Switch Executive. To get NI Switch Executive to recognize the change you must remove the IVI switch from the virtual device and then re-add it. The preferred manner for modifying source and configuration channel attributes is via the Channels panel in Measurement & Automation Explorer. Doing so will avoid such hassles.
Documentation Errata
The online help for NI Switch Executive is the most complete and up to date source for product information. There were some minor documentation issues found in some of the printed materials after they returned from the printer. That errata is documented below.
On pages 4 and 5 of the Quick Reference Guide, the Note section should read:
Note: The channel on either end of the bracketed list must not be:
Marked as a source channel (one or the other is valid)
A configuration channel
Note: Any channel within a route specification string that is not an endpoint must either be a configuration channel or must be hardwired to an endpoint.
On page 6 of the Quick Reference Guide, some error codes are not listed. See the online help for a complete list.
