Reading registers from Adam 5017 using Modbus Communication in LabVIEW

[Varghese89]

Hello LV experts,

I am trying to read voltage values from Adam 5017 8 Channel AI using Modbus Communication in LabVIEW for a project. I am new to LabVIEW and I am getting error 538179 at read holding register. Can someone please help me out :').

Please let me know if you need any further information. This is my first LabVIEW code. I am a student and I am interested in learning LV. I tried researching online but the error still remains :').

Usually I would first test using a GUI Modbus Master like QModMaster.

Are you sure you should be reading from a holding register but not an input register?

I also tried replacing Read Holding registers with Read Input registers which gives the same error 538179 at the Read Input Registers. I am trying to read the first four channels from a Adam 5017 8ch AI which is connected to a furnace. I can see the channel outputs from Advantech I/O Module Utility.

The issue was with the configuration. QModMaster really helped. Thank you so much for the information :')
