Bluescreen after pressing Stop-Button

[Tastenmann]

Hi,
I've got a problem again.

My system:
DIAdem 9.1 (evaluation), MS Windows XP

My program:
I read ascii data from an measuring-instrument (force, torgue) via RS-232. I use script-DAC-Driver to do this.
While measurement I display data with DIAdem-VIEW, and after that I export as an excel-file.

My problem:
That all works fine so far, but If I start measurement in DIAdem, the script-DAC-driver waits for bytes at serial port. If my instrument does not send data (for example if I decide not to start work), I can't stop DIAdem. If I press the Stop-button, I got a bluescreen and Windows reboots.
Is there any way to do this better (without bluescreen)?

Hi Nico,

That sounds not good. Please send me the DAC script and the DAC scheme so that I can do some tests. My email is
walter.ric@ni.com.

Best regards

I could reproduce your problem and solve it. (see attached file with modifications in Procedure SFD_init)
The reason was some errors in your code, but a blue screen or a spontaneously reset is a wrong reacton of diadem

1. You have't opend the interface corectly. Use the Open -command!
Remark: The Open-command and the IsOpen-function don't work properly in case of an error. The Open -command cause a runtime error and iterrupt the DAC-plan so the IsOpen -function can not work. This error is known at least since Diadem 8.0 but it is still unsoved.

2. You have not written a handler for the case of an timeout. I've done it for you.

3. Use the Read -function only with the second parameter "mode".
Remark: The description of "mode" in DIAdem help is
wrong. The right description is:
Bit 0 stop read/write at delimeter
Bit 1 send data including the delimeter
Bit 2 received data do not contain the delimeter

4. Diadem 8.x Script-Blocks did not work in asynchron mode with Windows XP. I don't know if it's solved in DIAdem 9.1

5. Your "Taktblock" was to fast. You should't takt the scriptblock faster then it can work. A RS232 is slow!
