I am trying to create a VI that links to a Modbus I/O variable that I access through NI DSM: The VI need to be able to select (hopefully by a drop-down) a test unit we have that is currently reading temperature. It then need to be able to access (trace) the historical data it has been logging and produce it to a waveform/graph. I also need the ability to specify what date/time range I want to see on the waveform/graph. I am trying to set this up for the lab technicians so they can select a test unit on the VI and view on a graph, the temperature data from the past day/week/ etc range that they need to see. If there is an issues, they need a way to save that range of data to an .xls so they can plot/print the data to present to superiors. Attached is the NI DSM and the VI that I have started to attempt to build. I'm very new to this and do not have access at work to the tutorials or YouTube as refereance sources. Am I headed in the right direction?
