I can't load onboard program

[Dmitry_NI]

I want to create digital pulses without any axis control by using on-board programming of PXI-7350 motion controller. I need it because i can't do it by using DAQ, or by using digital output of PXI-7350 without on-board programming. the main reason that i need PWM for 6 different motors, my controller has only 2. I need 0.9-2.1 ms of pulse duration to control servo motor, but limitation of non on-board program it 2.2 ms. i'm not sure that if i will use on-board program it will be faster, but i have problem that i can't load this program in board. I used standard example "digital pulses (1HZ) in a DO_WHILE LOOP.vi", and deleted all vi's about axis operation. of course this is not PWM, i just wanted to check that I have any signal on my digital output by using on-board program. I need just turn on and turn off after 1 ms one digital output in while loop, by using on-board programming.
At this moment when i run code nothing is happen,  there are no any signal on digital output and no error. Here is 2 case of code, but both are unsuccessful. May be somebody know what can i improve? If anybody can help me... thank you a lot!!
