List in write buffer?

[qweewq11]

Yeah manually is silly thats why i try to do someting about it 🙂 Thanks for the help i have now changed the manuall box to a "VISA resource name" box that goes in to the "VISA Open" box. The problem i have now is that it only shows like 5 instruments instead of around 80 instrumets as it should. Is it something that i missed?

Do you actually have all of those 80 instruments connected? How many appear in MAX?

[qweewq11]

I don't  really know what MAX is but maybe not all 80 are connected but at least it should be 10-15. I want it to show all TCPIP but it only showed 2 of them and they now disappeared so now it doesent show me anything. I don't know what is wrong since it only one output that goes in to the VISA Open input.

MAX is Measurement and Automation Explorer.

All tcp/ip is a tall order. Are they all vxi-11/lxi? Are they on the same subnet.

[qweewq11]

Im all new to this so i dont know what  vxi-11/lxi is. There are more than one subnet but there are over 10 on the subnet im working with.

Whether or not the instruments comply with the standard Ethernet protocols for instruments would be provided in the manuals. What sort of instruments are these? Make and model. Some may not be auto-discovered and you would have to manually add them in MAX.

[qweewq11]

I dont know what instrumets it is but obviously it doesent work so i guess i have to search manually. Is there a way to trough a subnet from ip .0 to lets say .100 and se which ones are connected or not and make a drop-down list of the ones connected so it looks pretty much like the VISA resource name function?

[Dennis_Knutson]

You have multiple instruments on your network and don't know what they are? What's the point since you need to know that in order to program them?

I suppose you could ping each ip. If there are other devices such as computers on the subnet, I don't know how you would differentiate between them.

[qweewq11]

That is just what my program does, you write an ip an the program tells you what instrumet it is. What you say is exaktly what i want to do. I want to ping all my 100 ip's an see if they answer and if they do i want to put them in the list to choose ip's from. How do i ping an ip and sort out all the ip's that dont answer?

[Dennis_Knutson]

There have been numerous posts on how to do a ping. Have you done a search?

Since you don't know what you have connected, how can you send a command that returns an identification? Are you sending *IDN?. That implies vxi-11/lxi.

I think there is a lot of information that is missing from your replies and the nature of your setup.
