Hello Labview experts
I am trying to make an automated test of a module that has a temperature sensor (DS18S20). Every time the temperature on the sensor reaches a threshold I will make the necessary tests and proceed with increasing the temperature of the climate chamber.
The manual doesn't mention anything about VISA which is what i usually use to control instruments. The only interface option on the chamber is ethernet
Can you help me figure out if there is a way to communicate with the climate chamber with labview?

You can still use VISA to communicate over Ethernet TCP/IP. This is how I communicate with most of my instruments. VISA is just an abstraction layer for communication buses (GPIB, serial, Ethernet).
I'm not sure what else you need here. Can you give more details on what you are stuck on?

Sorry for not elaborating what i am specifically looking for
Usually instruments include string commands in their manuals, to send to an instrument assistant in labview, which makes it easy to implement them in codes. The climate chambers don't have that, so i have no idea what and how to send a command that would change the temperature of the climate chamber

Unless you can find a ready made driver you absolutely do need the documentation for the commands for your device. For many instruments this is a seperate manual to the User Manual, often called Programmers Reference manual. Google for that for your device. If that fails request that manual from the manufacturer or the distributor from which you bought the device. A last defense would be to search for examples on the net in other programming languages, which are usually C or C#, but Python or Java are also possibilities, to learn the commands from them. Without that information you could just as well try to talk to a brick, the outcome is the same.
