Using labview to monitor specific tcp port

[udi741]

Hello,

Im using cRio-9067 and I have another devices that are connected to my local network (think about them as thermostats that wait for a command to come and tell them to take a sample, and after that they send the answer on the network)

so, my question is, how can I control them?

becasue i cant make a vi for each thermostat (they have a microcontroller inside them that read the commands from the network) , and my guess is that to create a tcp protocol using LabView I have to make a client and server VIs.

Is there any way to make only a server VI that sends the "take a sample" command and on the same time it will listen to the answer?

Thanks alot!

You need to read device documentation.
If you know communication protocol, you can "talk" with your device.
Your vi (server) send command (request) and wait for answer.
You don't need wriet another side (your device) on LabVIEW.

Actually, It is the other way around. Your network thermoststas are the "servers" while your LabVIEW application is the client that opens a tcp connection to the specific port on the remote device, sends a well formed command, and waits for a reply on the same connection.

So, start reading the manual about the details of the communication format. Do you have a link to the manual? Typically, these devices run very simple web services so this should be quite easy.
