Modbus Custom Device Feedback

[rkbull]

It appears that write single holding register for a master is not implemented.

Thanks.

Hi rkbull,

YES, that's true. I checked in the code. I'm going to fix that and upload a new version soon. What is the matter of emergency?

Hi Vincent_R,

My goal is to implement a real time Modbus master through veristand (using 2014). I followed the instructions above and also received a 'get main page' error. Also, when I open the project from source, it cannot find certain libraries on my computer (see below). All veristand software is up to date. Please advise.

Thanks,

Mike.

Hi Vincent,

This is the first error I see after copying the Modbus folder into the Veristand 2014 Custom Devices dir, right clicking on Custom Devices -> Modbus. I also noticed the 2014.1.0 version was taken off the site, any reason?

Thanks, Mike.

Hi,

For a reason I ignore, I cannot upload the source and built version 2014.1.0. I opened a request to web-team.

Send me a private message with your email inside and I'll send it directly by email.

Regards

Vincent,

     I am running Veristand 2014 on a PXIe-8100 and using the Modbus Custom device.  It seems to be working well for me, but I do get error when shutting down and deploying.  Below is a picture of what I am seeing.  Any idea what could be causing these?

Thanks,

Marty

Hi Marty,

Are-you referring to -2206 error and then -307730?

Regards

Vincent

Those two, as well as the one during deployment:

"Starting asynchronous custom device loops...

[Error: Labview: The LabVIEW Run-Time Engine cannot load the polymorphic VI. This error occurs int he stand-alone applications when the VI is polymorphis.]"

Or is this expected?

Thanks,

Marty

Hi Marty,

These are the known issues #2 and #3.

I plan to fix them in next version.

Can you, please, send me a private message which details your usage context, I'm collecting feedback?

Regards

Vincent

Thanks, I'll check known issues first in the future.  I am using TCP Modbus, but the description of known issue #2 sounds like it only applies to serial.
