Prerequisites for using the OMI web client

To be able to use the OMI web client to display OMI ViewApps, AVEVA System Platform must be registered with AVEVA Identity Manager. Perform this action in the Configurator either during or after installation.

Before you can make OMI ViewApps available to users, you must define and deploy at least one instance of a WebViewEngine. Assigning ViewApp instances to a WebViewEngine makes them available from the OMI web client. See Prepare to deploy a ViewApp: assign a ViewApp to an engine for more information.

Required web browsers

The OMI web client is supported with the latest versions of the Google Chrome and Microsoft Edge web browsers.

Preparation needed on remote devices

Any remote device where you will be using the OMI web client to run ViewApps must have a security certificate installed. This security certificate ensures private communication between the remote device and the WebViewEngine, enhancing the security of your data.

A remote device is any device that is not part of the same System Platform installation as the platform that hosts the WebViewEngine. This includes:

• Computers that have System Platform installed but point to a different System Management Server than the one that the platform hosting the WebViewEngine uses. This should occur only if you have two completely separate System Platform installations and want to access the OMI web client on one of those installations from a device hosting the other installation.

• Any device--such as a computer, workstation, tablet, or phone--that does not have System Platform installed.

Depending on procedures and policies at your organization, this security certificate may be installed by the IT department on all eligible remote devices, or users may need to install the certificate themselves before using the OMI web client for the first time. For instructions on installing the certificate on a Windows device, see Install a security certificate on Windows.

Note: For more information on security certificates, be sure to check the user documentation applicable to your operating system.
