Missing Pause Button

[Andrey_Dmitriev]

Hello, colleagues,

Can you explain please - why the Pause Button is missing in the given VI?

Checked all settings - all seems to be good. VI (LV 2013) is attached.

Andrey.

You need to allow debugging from VI Properties:Execution.

I know. Debug is allowed in the given VI:

Any other idea?

Just to be honest - this VI wasn't created from scratch - it based on "MB CRC-16.vi" from Modbus library.

For me it looks like small bug, or some "hidden" properties, which was used by NI.

Hm, never seen this before at an empty VI. Where does it come from? FPGA target? A private VI from a lvlib/lvclass?

Which version of LV (incl. f-patch)?

This is originally "MB CRC-16.vi" from Modbus library. (https://download.ni.com/pub/devzone/epd/nimodbus121.zip)

I just removed block diagram and change all settings to "New VI defaults", but this takes no effect.

Hm, i dont know if this is some weird bug in LV 20xx (at least 2013) or if this is something older LV versions put into the specific VIs:

I checked the LLB and all VIs which are disabled for debugging show the same behavior.

A simple workaround is of course to use "New VI" instead of "cleaning up the block diagram"....

Hi, Andrey!

I've got some time to investigate this issue (finally!) and found, that some additional internal flags were set for that VI, that's why you couldn't enable the Pause button. You may browse this thread to know the details.
