Vision Client Launcher Settings

You have the option of customizing the Vision Client Launcher Settings. This can be accomplished with either the GUI or by modifying a file on the local file system. Regardless of method, both utilize the properties specified under the Vision Client Launcher Settings Reference Table.

Launcher Settings

You can find the Settings button in the upper right corner of the Vision Client Launcher.

You can choose to use the default settings or customize your client applications. There are three different Action buttons in Settings in the Vision Client Launcher.

Export Launcher Config - Exports a configuration of the the Vision Client Launcher, as a JSON file (i.e., vision-client-launcher.json). Taking an export is useful in cases where you want multiple launcher instances to use the same settings. The content of the export file is based on the last saved configurations settings of the launcher.
Import Launcher Config - Imports your launcher configurations from a Vision Client Launcher export file.
Import Application Config - Creates a new client application configuration from an export, adding a new application to the launcher. The import file is the same generated by an application export.

When finished updating any of the client launcher settings, click the Save Changes button. Refer to the list of additional launcher settings in the reference table below.

Launcher Configuration Using JSON

In addition to using the GUI, these configurations changes can be made by modifying the vision-client-launcher.json file (created during installation of the launcher). The file is located at:

{user folder}\.ignition\clientlauncher-data\vision-client-launcher.json

The preferred method of configuration is with the GUI, but JSON modification is useful when attempting to load multiple application configurations simultaneously.

A reference to the various properties that can be modified via JSON are listed in the Vision Client Launcher Settings Reference Table. However, the JSON file has the following setting that isn't available from the GUI:

lock.configuration

When set to true, the application list and individual application configurations cannot be modified. Effectively restricting the ability to add applications and edit the launcher's configurations.

Trusted Certificates

As of release 8.0.13 you can add security certificates to the launcher. To use this feature, you must have installed a launcher from a version 8.0.13+ Gateway.

While attempting to launch an application, the launcher will check against the application's host Gateway, and attempt to automatically download any required certificates. In addition, certificates can be manually added using the example below.

Access Vision Client Launcher Settings by clicking Settings on the top right of the Vision Client Launcher window.
In the Trusted Certificates section, click the Add icon.
Navigate to the location of the certificate on your system and choose Open.
Information about the certificate is displayed. To view complete details, click the Expand icon next to Details. If everything looks OK, click Trust Certificate.
Once a certificate is imported, you can view its details by clicking the Information icon.

Delete a Certificate

To delete an imported certificate, access Vision Client Launcher Settings by clicking Settings on the top right of any Vision Client Launcher window.
In the Trusted Certificates section, select the certificate you want to delete.
Click the Delete icon.
You'll get a confirmation window. If the certificate is the correct one you want to delete, click the Delete button.

Export a Certificate

To export an imported certificate, access Vision Client Launcher Settings by clicking Settings on the top right of any Vision Client Launcher window.
In the Trusted Certificates section, select the certificate you want to export.
Click the Export icon.
Navigate to the location you want to save the certificate and click Save.

Launcher Application Settings

For each project application, you can update the default settings by clicking the More icon (three vertical dots) next to the project name, and select Manage to open the Manage Project Settings window. The Export command exports the configuration settings to a .json file. The Delete command deletes the project application from the launcher.

You can choose to use the default settings or customize your project client applications. There are three different Action buttons under Manage Project Settings in the Vision Client Launcher.

Launch Application - Launches the your application in the Vision Client Launcher.
Export Config - Exports your updates to the Vision Client Launcher file (i.e., vision-client-launcher.json). The resulting export file contains the last saved configuration of the application.
Create Desktop Shortcut - Creates a shortcut to your application on your desktop, using the last saved application configuration.

When finished updating any of the launcher settings, click the Save Changes button.

If the number of retries is exceeded, then the launcher will attempt to launch the Fallback Application. If the number of retries is exceeded, then the Launcher will attempt to launch the Fallback Application.	retries
Init Heap	The initial heap size (memory) for the client.	init.heap
Max Heap	The maximum heap size (memory) for the client	max.heap
Client Tag Overrides	Allows client tags to be overridden on the Vision Client. These are set using the table on the application configuration screen by adding rows with the names of the tags and the corresponding values.

The following feature is new in Ignition version 8.0.7 Click here to check out the other new features Added support for Vision Client Tag overrides within folders and passing client tag overrides with spaces by using a '+' icon as an escape character. This happens automatically if you are configuring overrides in the Client Launcher. To learn more about how to configure Client Tag Overrides, refer to Overriding Vision Client Tags.	client.tag.overrides
