pwm

[UBAP]

I am trying to use "DAQ assistant" in "NI-DAQmx" of the functions pallete to generate continuous pulses. [which "I think" can be used as PWM signal - ??]

and I am trying to realize the pulses at counter 1, which is port 2 line 5 [pin 40 of 6221]

However, I get the following message...

Error -201062.
Selected lines do not support buffered operations
Ensure only lines that support operations are being used in the task.

I already used counter 0 for edge counting application. so, I am left with only counter 1. 

1. So, any ideas how to solve this?
2. Is there a buffered line which can be used for outputting the PWM signal?
   

Thanks
