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.
