Timed Loop crashes when used inside Diagram Disable Structure or the error nodes are wired

[Kipp]

Hello,

I seem to have a couple problems using Timed Loops:

First, I put a Timed Loop that blinks an LED into the enabled case of a Diagram Disable Structure and the Timed Loop executed once, then the processor halted.

When I removed the Diagram Disable Structure, the application ran fine.

Second, I tried using the Error output and input nodes of the timed loop to propagate error from iteration to iteration instead of using a shift register. The timed loop does not execute at all in this case.

I've attached three files:

main.vi (runs as expected)

mainBadErroWiring.vi (doesn't run)

mainBadDiagramDisable (runs once) 

Has anyone else run into these problems, or is this unique to me?

Any ideas?

Thank you.

HI Kipp,

I will try and replicate this. I will keep you posted.

Hi Kipp,

DO you use the LEDs blinking/not blinking as a sign of what works and what doesnt? I talked to the R&D team for this and they say that there might be some features of the timed loop that are not supported. For now I would advise you to go with whatever works. I am sending the code to R&D to evaluate. I am sure shift registers are supported and that implementation should work for sure. 
 
Thanks,

Hi Jaidev,

I am using an LED to indicate functionality.  The LED is connected to port F4, and I use the BF Flag Toggle.vi to blink the LED. The BF Flag Toggle.vi just calles the C function "void  adi_flag_Toggle(uint32_t FlagID);". I was testing on custom hardware, but the code I posted to the forum was modified to duplicate the error on the BF537 ezKit using the standard blink vi.

I understand the R&D team is working on this, so I'll wait for hear back from them.

Thank you,

Kipp
