Test Station Configuration
A test station represents the physical location where a device under test (DUT) can be connected to the LTT. The LTT may have more than one test station. You need to define at least one test station.
To add test stations, simply click on the ➕ button. To remove them click on the ➖ button. You can however only add/remove stations at the end of the list, not in between. The stations are numbered automatically, starting from 1. You are free to change the number to something else at any time.
The number of stations determine how many parallel executions of the later loaded TestStand sequence file will be started. Each TestStand execution serves one DUT. The test station index is used to distinct between those executions in any form of display and file output. In TestStand you can access the current station index through a TestStand variable.
MesSy V2
If you use a MesSy V2 within your LTT, which is the standard case, the test station index defined in GUI relates to the station index defined in the MesSy configuration file.
As you can see in the picture above, each station index maps to a single MesSy with a given IP address. However there are more advanced station configurations possible, which are not part of this documentation. Refer to the comment section inside of the example MesSy configuration file for more informations.
If you create more stations than you have defined in your MesSy configuration, the GUI will show you a warning.
MesSy V1
If you want to use MesSy V1 you first have to change several other parameters as well. After restarting the GUI the test station configuration dialog will look like this.
Bus represents the last digit of the IP address of the MesSy to which this station is connected. The preceding part of the IP address is defined in MesSy configuration file (for example 192.168.222). A bus number of 3, for example, means, that this station is connected to the MesSy with the IP address 192.168.222.3.
Slot is a number to distinguish between multiple DUTs connected to one MesSy. It defaults to 1 and only needs to be changed if there are more DUTs connected to one MesSy. In fact, the combination of bus/slot must always be unique.
