VISA Lock and Unlock with GPIB
I'm currently working with VISA Locks and Unlocks to control calls to two devices on a GPIB.  It's the first time we've implemented the Locks and Unlocks in a program and we still get conflicts which come up with general statements such as "lock can not be found", or "device already locked". Our code consist... 6 May 2008 23:25

do I need rslinks and a kepware opc server
To get 12 words from an Allen Bradley 1500, over an ethernet link, from an existing Labview 6.1 application, will I need an RSLinks sever and an OPC server such as Kepware?  Or one or the other ... 7 May 2008 10:08

pulse oximeter
As a project. I am developing my own pulse oximeter and i am going to be using a DAQ 6211. There are four things i need to do with lab view which i have no idea how to do. I am very new to Lab view.   Ok the circuit i am building has a receiver and a transmitter. The transmitter has two LEDs that need to take c... 7 May 2008 06:40

NI PCI-1588 Windows XP Accurate Timing Device
Hi, I do not think that this device would solve your problem. This device allows you to synchronise over the Ethernet but you will still be acquiring timestamps from the Windows software clock( 1kHz). Some of the NI PXI controllers allow you to acquire timestamps at microseconds resolution when they run LabVIEW... 7 May 2008 03:31

How to change a specific bit to 0 or 1?
Altenbach, you are, in general, correct about the performance issues. I just made a small benchmark with my solution and dave's. dave's is about 6 times faster than mine.But now there is one thing i am wondering:My solution depends on the actual "length" of the number; the higher the value, the longer the vi takes for ... 7 May 2008 01:09

Equivalent of "C static local" variable?
How can i use "static locals" in the sense of unconnected control panels and avoid using property knots (value)? Using one of these always leads to mass using of it because of chain of destiny. Is it common to return a variable from a sub vi to the main program, which it can read and pass to the sub vi in the next ... 6 May 2008 23:25

More 8451 lockups
I am seeing the same problem.  I am trying to use the 8451 to log SMBus communication with a smart battery over a period of several months, but it will not even run for one hour without some sort of communications problem that the 8451 cannot recover from.    I am running the bus at 32kHz, I have trie... 6 May 2008 23:25

Save for previous version 8.5 to 8.2 generates code thatcrashes Labview (uses classes)
Hello again, I was able to save to a previous version 8.2 by moving the directory from:J:\35916 SMC\Test\System Test\Test Equipment Software\Software Code\Rev D\35916611CD SMC Test Equipment Software 1.12\Source\SMC Labview Testto:c:\SMC Labview Testand then working with it. LabVIEW keeps the entire directory structure... 6 May 2008 23:25
