I am currently working on a project using Modbus. I am trying to write a value into a DRO and I am having an issue that I cannot figure out. The value that I am trying to write into the
DRO flashes momentarily and then the DRO returns back to its previous value. The same behavior happens when I enter a value from the keyboard into the same DRO but do not hit the enter key.

Do I need a carriage return when dealing with Modbus and DRO values ? If so does anybody have a solution that they could share?

Thanks
