To elaborate, when I call the channel number, DAQFactory throws the error message "Invalid channel number." I've tried many different channel numbers and continue to get the same error.

Hi, I'm trying to set channels in DAQFactory for my U6. I haven't been able to access the channels; I've tried every channel number in DAQFactory to no avail. Can you please share the pinouts for the U6? I see the pinouts for the U3 in the application guide section 3.3 (see link below), but I don't see them for the U6. Thanks! https://www.azeotech.com/dl/labjackguide.pdf

Got it, thank you. I would like the raw data and peak values to live on the same data sheet. And I would like to create the file using a button. I'm having a hard time with this (I'm new to the software). I've created a button and want to write a quick sequence action to open a dialog, write the file name, and create the file. Then when I start the experiment, all the data starts logging to that file. My script at the moment is FileName = file.FileOpenDialog([],"C:\Users\austi\Dropbox\Product Testing\Cycle Testing Machine\Cycle Test Data\DAQFactor data\",".csv",[]) The dialog opens and I write the file name, however the file is not created. Can you help me with this?

This is probably an event-based logging problem. I'll expand a bit further.. I'm toggling two solenoids to control a pneumatic cylinder. I want to log the force the cylinder is exerting at max extension (max force at this position). The cylinder is controlled with a sequence, which I'll post here: while (N_cycles_executed < N_cycles) //Extension Output_contract=5 //turn off contraction solenoid Output_extend=0 // turn on extension solenoid delay(period_half) // extend for time period //Contraction Output_contract=0 //turn on contraction solenoid Output_extend=5 //turn off extension solenoid delay(period_half) //contract for time period N_cycles_executed++ //Index number of cycles by 1 endwhile

Hi, I'm logging data from a load cell. The cell is loaded periodically (every second in this case). I am only interested in the maximum load the cell reads every time period; I'd like to avoid logging many data points and having to filter the data later. This way, the file size is much smaller as well. How can I go about doing this? I imagine I need to write a script in the load cell's channel.. By the way, the time period is a global variable defined in a script, Auto_Start. Thanks!

This worked perfectly, thanks!

Hi, I am running a logging and control script on a LabJack U3-LV. Here is the issue I'm trying to solve. I am running a scripted sequence to toggle between two solenoids. I set the number of cycles and time period on a page, then run the sequence. I want the ability to pause the sequence, instead of having to stop and then restart the sequence. Here is a video showing the problem. I set the number of cycles to 10, then press "RUN" to start the sequence. I stop it after 4 cycles. When I restart, it starts the sequence again at 0 cycles. I would like to script it so it continues at 5 cycles, and then add another button to stop the program. Is this reasonable? Here's my code: global N_cycles //declare variable global period_half //declare variable global N_cycles_executed=0 //empty variable to use in loop while (N_cycles_executed < N_cycles) //Extension Output_contract=5 //turn off contraction solenoid Output_extend=0 // turn on extension solenoid delay(period_half) // extend for time period //Contraction Output_contract=0 //turn on contraction solenoid Output_extend=5 //turn off extension solenoid delay(period_half) //contract for time period N_cycles_executed++ //Index number of cycles by 1 endwhile
