  1. Hi, is it somehow possible to define/change the logging interval by means an active screen component etc. so that the user does not have to open the logging set properties panel? Gert
  2. Hi, is there a setting for full screen mode on startup, or is there a command line that can be used in a startup sequence for full screen mode? Gert
  3. I think I found the cause of my problem: During installation of the Labjack set up software using U12SetupV119.exe from Labjack the LabView RTE failed to install. I ignored this, thinking it was not needed. Now I have retried and managed to get the LV RTE installed. (Had to manually set the path for C:\Program Files\LabJackU12Legacy\LabVIEW_RTE_Install and open the lvrt.msi file. Now all three Labjacks are responding and the error messages are gone. I will continue to develop the application. (I already had the devices numbered #1, #2, #3.) This leads to a further question: The Labjack driver version is 1.19. Should I upgrade to 1.20 as you suggested to another forum member? I followed the instruction in that post, but on my system the ljackuw.dll file is not present anywhere. I am running XP Pro. If needed where should I put the dll file thanks again for your support, Gert
  4. Hi, I have run Daqfactory successfully with 1 Labjack, now I am building an application with 3 Labjacks. (target is 4, but I'm waiting for the 4th to be deliverd) I can't get Daqfactory to work with 3 Labjacks. In the Quick->Device configuration all Labjacks are visible and have received a device #. Also I can see input signals here (simulated input with potmeter). However in the Daqfactory alert panel I get a stream of "Can not claim Labjack" messages. Mostly 2 out of 3 are working (blinking LED), 1 not working with either LED continuous On or Off. I am not sure I understand the instructions for timing and offset in the help section. Anybody have some suggestions? For info: each Labjack will have two diff. analogue inputs (AI0-1, AI2-3), 3 single ended ana (AI4, AI5, AI6), 1 ana out (AO0), 2 DIO out (D1, D2), 1 DIO in (D8). Gert
  5. Hi, thanks for the fast response. This is clear to me now. Thanks, Gert.
  6. Hi, I have made an application that is working. The only thing that bugs me are some initial alerts during first start-up. I have managed to get rid of most alerts by assigning values to variables and channels. Because of limitiations in DaqFactory Express I had to split up into several sequences. Does somebody spot an error or I am misinterpreting the expression language? Gert. The alert message that I get are: C1040 Channel does not have any valid values: detect_pos_12_failure Line 4: detect_pos_12_failure Line 4 C1040 Channel does not have any valid values: detect_pos_34_failure Line 4: detect_pos_12_failure Line 4 Sequence: StartUp this is an auto-start sequence var.alarm1 = 0 // Populate DigOuts so X's do not display. var.alarm2 = 0 var.alarm3 = 0 var.alarm4 = 0 var.master_alarm = 1 Position_1_load.AddValue (9999) Position_2_load.AddValue (9999) Position_3_load.AddValue (9999) Position_4_load.AddValue (9999) beginseq(StartUp2) StartUP2 Sequence: StartUp2 alarm_stop_motor = 5 var.SGraphMin = 0 var.SGraphMax = 5000 var.SGraphWidth = 24 beginseq(detect_pos_12_failure) beginseq(detect_pos_34_failure) beginseq(master_alarm) Sequence: detect_pos_12_failure if (Position_1_load [0]< 1000) var.alarm1 = 1 endif if (Position_2_load [0]< 1000) var.alarm2 = 1 endif Sequence: detect_pos_34_failure if (Position_3_load [0]< 1000) var.alarm1 = 1 endif if (Position_4_load [0]< 1000) var.alarm2 = 1 endif
  7. Hi, I am using sequences in DaqFactory Express. I use a auto-start sequence named "StartUp" in which I assign initial values to a number of parameters. Then this sequence start some other sequences. This is working. My understanding is that all sequences are executed continuously. But if this is true, why isn't the StartUp sequence continuously assigning the intial values over and over again? Can somebody explane this behaviour? Gert.
