Click to open the MesSy configuration file ltt_messy_config.xml.
The MesSy signal configuration is where your DUT outputs and inputs are mapped to the corresponding MesSy inputs and outputs. You need to adjust this configuration depending on how your DUT's are connected to the LTT.
For training or demonstration purposes you can take the default MesSy configuration and go on with your setup.
The definition of the MesSy analog inputs are important for the signal definitions in LTT GUI's project wizard.
The file format for the MesSy signal configuration is different in MesSy V2 compared to MesSy V1. Depending on what you have selected during installation, the configuration file is for that MesSy version. If you want to switch to other MeSy versions read about changing the MesSy version.
You can find an example MesSy signal configuration file with all possible features and explanatory comments here:
- 50_LTT_SW\LTT TS\lib\IRS.MesSy\SignalConfig.Example.xml
- 50_LTT_SW\LTT TS\lib\IRS.MesSy\V1\SignalConfig.Example.xml
Changing MesSy Version
The new LTT software can be used with both MesSy V2 and MesSy V1. During installation you have to choose for one option but you can switch to the other MesSy version at any time afterwards.
Before you setup the MesSy version in LTT software make sure that LTT GUI is closed.
To switch from one MesSy version to the other you need to perform some configuration changes in different places. The following table describes those changes.
| Location of change | What to change |
|---|---|
| ltt_main_config.xml | Change the parameter <MessyVersion>X</MessyVersion> to: |
- 1 for MesSy V1
- 2 for MesSy V2 |
| ltt_messy_config.xml | The MesSy signal mapping file has a different format for MesSy V2 compared to MesSy V1.
You will find an example signal configuration for MesSy V1 here: 50_LTT_SW\LTT TS\examples\ltt_messy_config_V1.xml
You will find an example signal configuration for MesSy V2 here: 50_LTT_SW\LTT TS\examples\ltt_messy_config_V2.xml
Depending on what you have chosen during installation, one of those signal configuration files is copied to 50_LTT_SW\LTT Config\ltt_messy_config.xml for use in a LTT testplan.
If you want to create a testplan for the other version of MesSy, simply copy the corresponding MesSy signal configuration file from 50_LTT_SW\LTT TS\examples\ to 50_LTT_SW\LTT Config\ltt_messy_config.xml. | | LTT Template.seq | With the LTT installer there comes a LTT template sequence file - one for each MesSy version.
You will find the LTT template sequence file for MesSy V1 here: 50_LTT_SW\LTT TS\lib\IRS.MesSy\V1\LTT Template.seq
You will find the LTT template sequence file for MesSy V2 here: 50_LTT_SW\LTT TS\lib\IRS.MesSy\LTT Template.seq
Depending on what you have chosen during installation, one of those template sequence files is copied to 50_LTT_SW\LTT TS\LTT Template.seq.
If you want to create a testplan for the other version of MesSy, simply copy the corresponding template sequence file to 50_LTT_SW\LTT TS\LTT Template.seq. | | LTT GUI - Project Wizard (F3) | Open the project wizard in LTT GUI and go to Test Station Configuration.
