How to configure several counters and out terminals in one task?

[mingren1238]

I use NI USB-6341 board and it has four counters. I want to configure several pwm generations with different duty and frequency in one task.The vi which I made below can not generate any pwm signals.I hope someone can teach me how to configure! Thanks in advance!

I won't swear to this nowadays, but time was when you could not include more than one counter (configured differently) in one task.  NI-DAQ wouldn't allow it.

If you try, you get an error - what error code do you get?

The error code is 89137,the error happens in DAQmx Start Task.vi:722001. Specified route cann't meet the requirement.

thanks!

But I want to synchronize two counters and need to change the PWM duty in every loop. How can I ensure the two counters generating PWM signals synchronously. I have read the examples on this forum using AI input and digital trigger,but situations are different.Waiting for your reply! Greatly apprecited!
