Programming Modbus Driver LabVIEW

[parker300]

Hello,

I am trying to communicate with an Omega Platinum Series Meter through micro-USB. I have downloaded the device drivers and it uses Modbus as protocol. The pallete, which I attached a screenshot of, has many options and I am not sure what to choose and how to go about programming it. I've attached a start of a VI and the manual for my device. 

Thanks for the help!

Did you get the driver from here? https://www.omega.com/en-us/control-monitoring/meters/universal-input-meters/dppt-series/p/DP32PT

It comes with an example. Open the project Platinum Modbus.lvproj and see Platinum_MB_Example Serial Master.vi to get going.

After downloading the drivers, start with PLatinum_MB_Example Serial Master.vi

cordm, LVninja,

Thanks for the reply. I ran the example file from the driver and am getting a timeout error 6101, regardless of what I set the timeout length to. 

I understand that this is a communication issue with the serial port. What can I do to fix this?

If you get a timeout error I suspect that some configuration is off. Did you do this?

Make sure that what you configure in the program matches the device configuration. Refer to pages 13 & 14 of the Panel user manual.

Thanks! I was able to alleviate the timeout error. The issue now is that when I try to read the value from my device, I get 0. I have the device reading a pressure of about 15 psi.
