Good Day!
Ihave Trouble using modbus.. I wanna configure a shared variable for a specific channel in my daq..
Im using NI 9426 in the slot 1 of NI CRIO 9075..
I cant understand how to pick an data item in Creating Bound Variables
Could somebody give me an example of data item, i wanna make an shared variable for DI0 of NI 9426..
Im using I/O server in ethernet..
Thank You!

Are you using the LabView DSC module? OPC server ? Modbus library? There are so many ways labview can communicate to a Modbus master or Modbus slave? We need more information. For a cRIO I would use the Modbus library to communicate to a Modbus master.

Hi!
I'm using modbus library (i think).
I'm configuring modbus in the project explorer so that i can easily drag the shared variable to the VI..

Yeah the link u gave is correct..
But I cant understand the syntax of the data item...
I just want to create a bound variable that is connected to the DI0 of the NI 9426...
and create a VI where i can just drag the created variable then connect it to boolean led
so when the NI 9426 DI0 recieve a HIGH it will trigger the boolean led..
