Connecting and adding device

[gltfrs]

I am trying to connect a counter and tachometer to Labview. How can I do these two things so the labview can just read the value of these two devices? The tachometer model is 47100 brand is Durant

Looks like the Durant has RS232.

Search the NI Example Finder for "serial read and write".

Instead of making someone here do your research, can you at least provide how the instruments connect to the pc and the communication protocol (i.e. RS-232, Ethernet, etc).

I have already connected and did the research I am using RS-485 so I can connect both counter and tachometer, but I couldn't find this devices on LabView.

Did what research?

What made you think LabVIEW can work with directly with RS-485?

[gltfrs]

Yes it does work if you use it as a Master-Slave with RS-485

Serial devices are not 'detected' by LabVIEW. Serial ports are detected by MAX and then you can list the available resources in LabVIEW and search through them to determine what instrument is connected where. You will have to write your own instrument driver/code.
