Watlow F4 communication error need help

[Joe_S]

Hello,

The error message you are receiving seems to be a custom error generated by the VI itself.  After looking through the vi libraries myself, I am having trouble finding the source of that error code.  Have you modified the instrument drivers at all?  Also, do you have the LabView Modbus Library installed on your computer?

Regards,

Joe S.

Hello,

  I haven't modify driver at all,  and I haven't install modbus library but I will try to install it.

What I try to do ,I use configure profile.vi  and select start profile2 to operate chamber but it doesn't work.

BTW is there any sample program to call profile to run?

Hello,

Any examples that might be available using the Watlow instrument drivers can be found in the NI Developer Zone, but there may not be an example that is specific to what you are looking for.  The more important issue is to figure out why you are seeing this error and where it is coming from.  I would recommend that you double-check that you are using the correct drivers for your specific device, then to single-step the execution of your program to see exactly where the error is generated and the offending VI.  Finding the code that generates this error will allow us to get a better idea of what is going wrong.  Let me know!

Regards,

It seems that you are calling the profile twice and the first time its configured incorrectly and so the second one is bypassed.

delete the "string" "PINK" box and set the profile number to 1 and then delete the second profile call and i believe that should work.... try it.

Hi,

I ran into the same issue. I could change the baudrate to  19200 at device driver from windows. But failed initialization with the same driver downloaded. Any suggestions?

Thanks,
