Check out the example at examples\Data Communication\Protocols\TCP\Simple TCP\ It uses the TCP primitives without EOL.

If the red dot is scary, you can just drop in a "to fixed point" in there. It explains the conversion (rounding mode and overflow mode) a bit better. In this case, the output is exactly the same as the input in the same way that 16 is the same as 16.0.

I don't have a canned solution for velocity profiles. I'm sure there's something nice out there. It might be possible (though, probably there's quite a bit of effort involved) to roll your own controller. You could use a 9401 to output a PWM signal to something like an H-bridge, if you're micro-stepping, you'll have to use another module, maybe a 9221, to measure the current out to the motor, etc.

What sort of interface are you looking for? RS232? What controller are you using? PC? CRIO? Soft motion rather fancy—what sort of features do you need? Just regular acceleration, velocity profiles? Encoders?

Just scale it

If you don't want to use a feedback node, another option is using a local variable (see example below) It sounds like you're trying to process losslessly. If that's the case, you usually need some sort of buffer. In this example, I use the event queue as my buffer.

Initialization behavior is well defined in the settings of the feedback node. https://zone.ni.com/reference/en-XX/help/371361L-01/lvconcepts/block_diagram_feedback/ I'm not sure what you mean by force. Are you trying to make it into a d latch?

To clarify the previous post, the two loops can share a wire as long as that wire is an input to both of them. If the wire is an input from one and an output to the other then the loop that is expecting the input will have to wait for the other loop to output the data. If you intended to use that wire to communicate data between the two loops, maybe convert the wire between them to a channel wire?

I'm not too familiar with the FIFOs so I can't answer those questions but I noticed your error handling is a little weak and doesn't capture errors while you're inside the loop. Usually you want to run your timed loop at your control rate (some target rate you choose). It's a little less common to try and run it losslessly as you might trying to do. If you wanted to run losslessly, you could maybe set the loop time to 0 or maybe create a timing source from your task: http://zone.ni.com/reference/en-XX/help/371361R-01/glang/create_timing_source/

I think you need to replace your rotate array with another for loop with your wait inside. The inner for loop will autoindex your array and output the values one by one. If you post a VI or a snippet, we might be able to better show you what we mean.

The outer one can't turn true while you're inside of the inner one. It's just like a nested if statement in C.

It should still work in RT even if it doesn't show up on the pallets. Try it. Or, check out the underlying code and copy that.

Basics lesson 1 has that VI in the lower right quadrant. You can also search for the VI by name using quick drop Also, on the help page it tells you the owning palette (Timing VIs and Functions) so you can find that VI.

I recommend you change your booleans on the main panel to Latch When Released I modified your bool test subVI so it would pop up and stay active until the user closed the panel

It would really be nice to see some code or even like just the concept to see what you're talking about. Have you seen this VI? http://zone.ni.com/reference/en-XX/help/371361P-01/glang/stall_data_flow/
